A Tik Tok account producing a series of “Seattle serial killer on the loose” videos has lucked into a viral hit with a clip about two bodies found in 2016 and 2021 in Capitol Hill’s Interlaken Park The information in the 16-second video is out of date and ignores key findings and facts reported years ago by CHS The video centers on two unsolved deaths in the park and claims to tie the cases together The King County Medical Examiner says McKendrick was killed about a week before her body was found on the afternoon of Sunday May 30th in a small stream below the park by a homeowner who called 911 about the sad discovery It is not clear where McKendrick was killed Police say the on-scene investigation yielded “no obvious information about the circumstance that led to the death” due to the condition of the body and the location in the area of the small The site is near E Interlaken Blvd that winds through the park — a popular route for walkers and bicyclists that is closed to motor vehicles The video spreading on Seattle social media this week claims a second woman’s body was found in mysterious circumstances in the park but leaves most of the details vague while including a photograph from CHS coverage of the story from eight years ago In 2016 CHS reported on the discovery of human remains in Interlaken by a father visiting the site in the leafy park’s greenbelt where the body of his homeless son had been found five days earlier The son, Jon LeBaron, 29, had struggled with drug addiction and homelessness for nearly eight years before he went missing Police told LeBaron his son had likely been dead for two months when he was found on August 30th by two people who said they were hiking through the woods when they noticed the 29-year-old’s shoe The body referred to in the video was found by LeBaron’s father as he searched for the site where Jon was found The father found what appeared to be a human skull and an old camp site overgrown with ivy according to the police report on the investigation and scrambled back up to the streets above Interlaken to call police Arriving officers found skeletal remains and cordoned off the area for a death investigation the skull and any skeletal remains were not “positioned” to mock police and the body was not female The medical examiner later determined that the remains found that late summer in Interlaken were those of an adult white male between the ages of 25 to 50 He was found near a living site along with “multiple pairs of shoes” that ranged in size from 9.5 to 13 The investigation also identified a defect in the bone above the man’s left temple “possibly an old surgical shunt.” Case #16-1753 remains part of the King County Medical Examiner’s roster of unidentified remains Many of those involve people living unhoused The case of Necia “Q” McKendrick-Mendez, meanwhile, is also going cold along with a handful of killings like hers in recent years with shared factors: Homeless. Gay.

campfire that was not extinguished properly and was left unattended officials say 256 personnel were battling the flames Saturday, June 15, 2 p.m.: Containment of the Interlaken Fire near Twin Lakes had reached 15% as of early Saturday afternoon, June 15, according to the U.S. Forest Service A press release was issued Saturday morning by the Type III Incident Management Team handling the response to the fire through the Interlaken Fire Information Facebook page 277 personnel were on scene battling the blaze as of Saturday morning The release states that firefighters “took advantage of the cooler weather” Friday to make continued progress building a fireline at the edge of the wildfire the fire was progressing slowly towards the Interlaken Trail Saturday morning and firefighters planned to use the trail as a fireline Firefighters had completed a direct fireline along the entire southwestern edge of the fire and planned to work to improve and secure the line Saturday aided by helicopters outfitted with water pumps and hoses firefighters were set to continue building direct handline at the edge of the fire progressed to the edge of a prescribed burn that took place in 2018 The prescribed burn area is acting as a holding feature in the east slowing and even stopping the progress of the wildfire and giving firefighters direct access to the area Public health impacts from smoke were minimal near the Interlaken Fire as of Saturday morning wind and atmospheric mixing were expected to loft smoke away from the surface Saturday windy conditions and a drop in humidity levels which “could create critical fire weather conditions,” according to the release A Temporary Flight Restriction is also in effect over the fire area due to the possibility of unrelated flights impeding firefighting efforts 9 a.m.: The Interlaken Fire near Twin Lakes continues to burn on an estimated 585 acres —  just less than a square mile — but was 5% contained as of Friday morning Investigators said the human-caused wildfire originated from a campfire that was not extinguished properly and was left unattended officials say 214 personnel were battling the flames a community meeting about the Interlaken Fire is scheduled at 10 a.m A video will be uploaded to the Interlaken Fire Information Facebook page following the meeting Firefighters worked into the night Thursday to protect historic structures near the Interlaken Resort as fire activity picked up near the northwest corner of the wildfire Fire managers determined late Thursday that there is now about 5% containment along the northwestern edge of the fire the terrain is steep and full of dead and downed lodgepole pines The fire is reportedly moving slowly through the underbrush in this area which firefighters plan to use as a fireline crews are building a direct fireline and plan to connect it to a local roadway More crews are expected to arrive in this area Friday to help construct the fireline Firefighting crews are also reportedly gathering information on the location of structures in private land near the southwest edge of the fire are assisting firefighters by using boats to bring supplies across the lake to the fire area More helicopters are also expected to arrive at the fire with two Type 1 two Type 2 and one Type 3 helicopter planning to assist at the Interlaken Fire on Friday Trails in and around the historic Interlaken Resort are closed due to the fire and a temporary flight restriction is in place over the fire as operation of drones or other aircraft will interfere with firefighting efforts

It's also a reason why the GoldenPass line hasn't been as popular as its panoramic counterparts, like the Glacier Express instead of requiring travellers to change trains in the middle of the journey the GPX can make the three-hour-15-minute journey directly thanks to the revolutionary "variable gauge bogie" developed in 2022 after 15 years of research and costing 89m Swiss francs (£80m) was publicly funded by the cantons of Vaud This innovation facilitates seamless transitions between narrow and standard gauges and voltage changes within seconds effectively enabling a train to jump tracks while moving It's a groundbreaking new standard in rail travel – not just in Switzerland "[The GPX] is a link to our past and our future," said Frédéric Delachaux explaining that it realises the centuries-old dream of linking Switzerland to Europe by rail via the Alps as the train's elevation shifted ever so slightly (rising about 200 mm) to accommodate the gauge attrition and platform height an engineering marvel was happening right below my feet – even if only a discerning train aficionado would notice it "It's a big frustration for us in marketing because you don't feel anything!" lamented Delachaux the gauge change is displayed on a screen to passengers as it's happening • A new night train connecting some of Europe's great cities • One of the world's most scenic train lines • Europe's narrowest-gauge train While there are other trains in France and Japan that can move a few centimetres "this is the only train in the world that moves 43cm" It's perhaps no surprise that the Swiss were able to pull off this engineering feat. Living in a landlocked nation that's 70% mountainous and filled with some 1,500 lakes people here have long had to negotiate the obstacles posed by their challenging terrain – and along the way exemplified a certain determination and ingenuity that is decidedly Swiss As Clarence Rook wrote in his 1907 book Switzerland and Its People: "There are bigger mountains in the world than may be found in Switzerland But you will nowhere find in so small a space so many triumphs of engineering The Swiss roads and railways stand as a monument to the victory of human skill over physical obstacles." And so, I wondered, are there plans to connect the entire GoldenPass line from its origin at Lucerne to Montreux "That's the new dream," said Moix "It's also a technical issue because between Lucerne and Interlaken we have a cog railway That means we'd need to add a cog system to the GoldenPass Express and that takes a lot of time – another lifetime."

Trends, Challenges, and the Future of Interoperability HBM4 Boosts Memory Performance for AI Training Using AI to Accelerate Chip Design: Dynamic, Adaptive Flows As data consumption grows and chip designs evolve to meet this demand Interlaken is the ideal high-speed chip-to-chip interface with efficiency Interlaken addresses modern chip-to-chip design challenges System and chip designers are challenged like never before The continuous growth in data consumption is driving demand for higher speeds and capacities but designs also need to consume less power-per-bit at a lower cost-per-bit but not at the expense of efficiency and cost One of the chip design elements that is most critical is the chip-to-chip interface Poor chip-to-chip interface design can lead to system bottlenecks and unreliable data transfers that can compromise the entire solution Choosing the right chip-to-chip interface technology is therefore critical Interlaken provides a high-speed interface with efficiency The design of the Interlaken interface ensures low power consumption and cost-per-bit without compromising on performance The challenge when connecting chips is to find an economic means of transferring data between chips on the Printed Circuit Board (PCB) implementation This means as few pins and PCB physical connections serial interfaces are preferred as they drastically reduce the number of pins required Serial interfaces consume less power and are less sensitive to electro-magnetic interference compared to parallel connections Serial interfaces have fewer connections that can be spaced effectively to reduce these effects This increases the effective reach of the interface leading to longer trace-routes and more flexibility during design This decreases the complexity and cost of PCB and chip design One of the important requirements for chip-to-chip interfaces is that they need to be transparent Data needs to be reliably transferred from one chip to another without relying on higher layer protocols the chip-to-chip interface needs to ensure that there is “bounded disparity” which means that the number of ‘1’s and ‘0’s transmitted are as equal as possible a Direct Current (DC) offset is introduced that can affect coupling capacitors or transformers on the line This can lead to challenges in identifying voltage levels accurately and retrieving clock data an effective block coding mechanism is needed that will reduce the “running disparity” the difference between the number of ‘1’s and ‘0’s The next step is to ensure that bits have not been corrupted during transmission An effective Cyclic Redundancy Check (CRC) for each data transmission can indicate if errors have occurred while a Forward Error Correction (FEC) can be used to correct any errors it is desirable to ensure that the flow of data is controlled so that receiving chips are not overwhelmed For bursty data that is switched to different locations flow control can be extremely effective in managing data bursts and ensuring maximum throughput each application will have a chip-to-chip interface that is optimized for that specific application but it is far more desirable to have an interface that can be configured and reused to meet different requirements Enabling the chip-to-chip interface to scale to meet different data rates enables maximum reuse across multiple designs and applications the ability to configure the interface to fit different SerDes (Serializer/Deserializer [1]) lane configurations provides maximum flexibility in meeting application needs ASIC chip designs are often prototyped on FPGAs first It is therefore desirable to have a chip-to-chip interface that can not only scale but also migrate from FPGA platforms to ASIC designs with minimal impact which requires chip-to-chip interfaces that can be implemented on either platform Interlaken provides a standardized serial interface that is agnostic of underlying SerDes implementations It can also be configured to support multiple lane configurations Interlaken ensures reliable transfer of data over as few physical connections as possible Interlaken provides mechanisms to ensure the integrity of data transfer as well as manage data flows to ensure that the chip is not overloaded These mechanisms effectively increase the operational reach of Interlaken interfaces to allow longer chip-to-chip interfaces Interlaken was introduced in 2006 by Cisco Systems and Cortina Systems to address the need for both a high-speed chip-to-chip interface and a reliable packet transfer mechanism Available alternatives at the time were XAUI and SPI4.2 and both inspired the design of Interlaken was originally introduced in the IEEE 802.3ae standard for 10 Gbps Ethernet the 10 Gbps Ethernet protocol stack defined a new parallel interface between the MAC layer and the PHY layer called XGMII (10 Gbps Media Independent Interface) System and chip designers needed the option of implementing the 10G MAC layer and PHY layer on different chips the XGMII interface requires over 70 pins to connect the MAC and PHY As a parallel interface with a high number of connections the effective reach was relatively short at only 3 inches or 7.5 cm This made XGMII an impractical chip-to-chip interface XAUI was defined as an alternative “XGMII extender” interface XAUI is a serial interface that maps the parallel data of the XGMII interface to 4 serial interfaces operating at 3.125 Gbps Each interface requires two connections leading to a need for 16 pins for full duplex operation which is a dramatic improvement on the over 70 pins used by XGMII The effective reach can be longer than 40 inches or 100 cm but is specified normally to 20 inches or 50 cm It is this efficiency that inspired Interlaken designers to adopt a serial interface rather than a parallel interface The disadvantage of XAUI is that it is limited While the 8b/10b block coding used in XAUI helps in improving running disparity A CRC is used to ensure that bits are transmitted correctly This is not needed for communication between the MAC and the PHY but can pose a problem if XAUI is used for other chip-to-chip applications the best example of an interface implementing this capability was the SPI4.2 (System Packet Interface level 4 phase 2) interface published by the Optical Interconnect Forum (OIF) in 2003 SPI4.2 was designed as a parallel interface between PHY devices and link-layer devices for 10 Gbps Ethernet One of the big advantages of the SPI4.2 interface is that a separate flow control interface is provided that allows the First-In First-Out (FIFO) buffer status of the receiver to be communicated back to the transmitter The separate flow control interface enables the transmit and receive data flows to operate separately with their own flow control for each virtual port This ensures that the FIFOs at the receive side are not overloaded or starved where the line rates on the transmit and receive sides can vary This was the case with 10 Gbps LAN Ethernet which operated at a different rate to 10 Gbps WAN Ethernet and OC-192 Interlaken has adopted similar rate matching and flow control mechanisms as SPI4.2 using it as an inspiration for design Interlaken for high-speed chip-to-chip interfaces Interlaken was conceived as the best of the XAUI and SPI4.2 implementations channelized interface of XAUI with the flow control capabilities of SPI4.2 to provide the ultimate high-speed chip-to-chip interface Interlaken is designed as a serial interface similar to XAUI and can achieve long reach using fewer physical pin connections It makes it possible to use Interlaken in a variety of applications from system-level chip-to-chip interfaces to chiplet-to-chiplet interfaces within a package a meta-frame concept is introduced to control transmission of control and data words on each lane a set of words associated with the meta-frame are sent along with the payload of control and data words Click to enlarge Figure 1: Interlaken striping and word format Data is transmitted across the Interlaken interface in configurable bursts which are a subset of the data to be transmitted is 32 bytes divided into 8-byte increments known as “words” BurstMax is defined as a multiple of 64 bytes the data word bursts are bookended by control words that provide additional information on the data being sent The format of the control word is shown in Figure 1 Each burst is associated with one of up to 65536 logical channels which can represent ports or any other logical stream of data This allows different data streams to be mixed while meeting tight latency requirements Click to enlarge Figure 2: Transfer of 72-byte packet with BurstMax = 64 bytes and BurstShort = 32 bytes An IP packet can be transmitted without interruption over several bursts This is known as “Packet Mode” segments from multiple packets can be interleaved This is known as “Segment Mode” The individual segments can be interleaved on different channels The two modes enable the chip-to-chip interface to match application needs it might be more important to ensure that packets are not interrupted and sent in full using Packet Mode Segment Mode can be used to avoid head-of-line blocking and delays When the amount of data to be transmitted is less than BurstShort Interlaken includes idle control words that can be inserted to meet the burst size requirements the start of the packet is indicated by a control word with a “Start of Packet (SOP)” field The packet data is segmented into multiple 8-byte data words according to the configured burst size parameters with idle control words inserted as necessary The final control word contains an “End-of-Packet (EOP) Format Field” which not only indicates the end of the packet transmission but also how many bytes of the last data word are valid Interlaken provides several reliability mechanisms Interlaken is designed to be completely transparent thus providing different reliability mechanisms to ensure correct data transmission Interlaken uses a more advanced block coding scheme to reduce running disparity as much as possible where the 8-byte words to be transmitted are mapped or “striped” on a sequential basis to a 67-bit block Using a larger block for encoding is more efficient and uses less bandwidth the reverse operation occurs where the 67-bit block data is mapped to 8-byte words This is a similar mechanism to the 64b/66b block used in Ethernet implementations and defined in IEEE 802.3ae for WAN applications but includes the addition of an additional inversion bit The inversion bit indicates whether data has been inverted allowing mechanisms to reduce running disparity even further the Interlaken implementation scrambles the 64-bit data to improve running disparity but leaves two added “sync” bits unscrambled to enable control words to be identified Interlaken uses a 24-bit CRC in the control word that is calculated across all data in the burst across all lanes One of the major advantages of the Interlaken interface is flow control Interlaken implements a per-channel control mechanism which enables the receiver to communicate backpressure The flow status of each channel is communicated using a single bit indicating either a ‘1’ for ‘XON’ state or a ‘0’ for ‘XOFF’ state per logical channel Data can be transmitted on a channel as long as the flow control status is XON Interlaken provides the option of using a ‘calendar’ to indicate the status of all logical channels and the link at once status is provided for the link as well as each logical channel with a single XON/XOFF bit Interlaken supports both out-of-band and in-band flow control allowing for efficient interface implementations Out-of-band flow control requires separate pins while In-band flow control information is indicated in the flow control field of the control word it is possible to meet the data flow requirements of each channel individually Should the receive buffer of an interface become congested the flow control can ensure that the transmission of data is managed to address this situation An additional control feature is Rate Matching This ensures that the data rate of the Interlaken interface is matched to the downstream service This can be helpful in situations where two chip implementations operate with different clocks or there is a need to convert to different data rates One of the features of SPI4.2 that was not originally implemented in Interlaken was Hit-Less Bandwidth Re-Provisioning channel priorities to be changed dynamically or channel bandwidth to be changed without affecting traffic on the interface this capability was added with the Interlaken Dual Calendar Extension Revision 1.0 A calendar selection bit (CAL_SEL) is added to the flow control word to indicate whether the active calendar or shadow calendar should be used (referred to as CAL0 and CAL1 respectively) CRC checks are applied at multiple levels of Interlaken a 24-bit CRC is calculated across all data in the burst a 32-bit CRC is calculated across all words in the meta-frame Out-of-band flow control is also protected with a 4-bit CRC These multiple levels of CRC checks ensure maximum data integrity CRC checks can only indicate errors and not correct them the Interlaken Alliance published the Interlaken Reed-Solomon Forward Error Correction Extension Rev 514) FEC can be used in Interlaken to provide additional data integrity protection the Interlaken Alliance provided an extension called Interlaken Retransmit Extension Revision 1.2 which enabled buffered data retransmission in the event that a CRC error is detected Because Interlaken is designed to be configurable and independent of the underlying physical lane implementation This distinguishes Interlaken from both XAUI and SPI4.2 as both are based on a fixed number of connections It means that the same Interlaken implementation can be configured to meet different chip-to-chip interface design requirements the chip-to-chip interface could be based on a single lane at full data capacity it could be based on 4 lanes each operating at a quarter of the data capacity Click to enlarge Figure 3: System- and board-level applications When combined with the ability to define logical channels the chip designer is provided with multiple configuration options that enable Interlaken to scale from single lane 10 Gbps connections to multi-100 Gbps connections These scalability capabilities provide chip designers with reuse opportunities across multiple designs and applications Because Interlaken is standardized and independent of the underlying physical implementation it allows a chip designer to design a chip-to-chip interface for an FPGA platform that can be reused should the design be migrated to an ASIC platform As a chip-to-chip interface that is independent of the underlying physical implementation Interlaken can be used in multiple applications Because of its configurability and scalability it can be adapted to meet specific needs while ensuring a narrow the data processing units need to be connected to the data input/output logic that can be a single pizza-box motherboard where MAC/PHY chips are connected directly to the data processing unit (e.g. Interlaken can be used to connect the MAC/PHY chips to the data processing unit or switch The Interlaken logical channels can represent networking ports or switching ports such as control or management data or different types of payload data Interlaken flow control and rate matching can be used in switch systems to manage the flow of input/output data based on the FIFO buffers for each switch port ensuring that no packet data is dropped in the system Because Interlaken is independent of the communication protocol or underlying implementation the designer can choose where chip logic should reside the designer can choose how many sub-layers of the physical layer should be implemented close to the port and how many should be centralized in a separate chip This can be seen in Ethernet implementations but also in 5G RAN implementations with split-PHY eCPRI interfaces the data processing or switch units can be separated from the data input/output logic on separate plug-in boards connected over a backplane the Interlaken chip-to-chip interface needs to connect the same chips to each other Thanks to the built-in reliability and relatively long-reach of Interlaken interfaces Figure 3 provides examples of system- and board-level applications many of the same advantages can be reaped as at the system level While network adapters have traditionally been focused on transferring data to and from central data processing units modern adapters are increasingly offloading data processing tasks with more advanced capabilities Adapter design has thus become more complex with more processing and memory chips on the adapter requiring high-speed chip-to-chip interfaces As board-level design is limited due to the size of the board (e.g. Interlaken provides advantages such as reducing the cost power consumption and complexity of the board design because only a few physical lanes are required to be implemented Since board designs can involve multiple chips in the data path Interlaken can be used to meet the individual requirements of each chip interface with respect to number of lanes and speed rates Flow control and rate matching can be used to match data rates in applications where there can be clock or data rate discrepancies between chips In both system- and board-level applications co-processing chips are used to offload specific tasks they are focused on processing header information or specific types of packets or some other subset of the data being processed the Interlaken Alliance has defined a lightweight version of the Interlaken protocol called Interlaken Look-Aside This was published in 2008 as Interlaken Look-Aside Protocol Definition Revision 1.1 The Interlaken Look-Aside protocol is similar to Interlaken an even more compact and lightweight implementation can be adopted For co-processor applications that are used to processing a small subset of the total data the Interlaken interface can be used to directly connect the co-processor and main processor global data consumption in 2020 increased 30.4% compared to 2019 and is expected to grow 26.9% per year until 2025 This requires higher speeds and capacities which means bigger chips and greater power consumption Power consumption is a major challenge for data centers and is as important as speed and capacity in decisions on which networking technology and chips to deploy size and power consumption of systems and chips as much as possible This is leading chip designers to break up designs so that they can either be implemented on multiple physical chips or on ‘chiplets’ which are smaller chip dies that are combined with high-speed interfaces to form an efficient solution within a single package This technique has been used by CPU manufacturers for some time and can also be seen in “System-on-Chip” (SoC) solutions For chip designs that involve multiple separate chiplets Interlaken can provide the ideal interconnecting interface This is especially true for high-speed chip solutions it is important that it operates as if the implementation was on a single die the interconnecting chiplet interface should not introduce any observable effects The reliability and flow control provided by Interlaken ensures that the interface is self-reliant as well as being efficient It enables different chiplets with different requirements to be combined Interlaken can configure the interface and control the data flow to match requirements This allows efficient chiplet designs to be re-used in multiple packages Another chip-level application of Interlaken is System-on-Chip (SoC) solutions where FPGA logic is combined with hard-coded blocks or separate dies in the same package A good example of this is SoC solutions supporting digital or even analog signal processing The signal processing functionality can be provided on a separate die that is optimized for this kind of functionality Interlaken provides an efficient and reliable interface for connecting blocks and separate dies with the FPGA logic Because the Interlaken interface is standardized and independent of the underlying implementation it is also agnostic of the FPGA platform provider and can thus be used in solutions that need to support multiple FPGA vendors The FPGA can also be migrated to an ASIC without major impact Suitable for a broad range of high-speed applications and reuse a single Interlaken interface design can be reused to meet a broad range of applications making it an efficient and profitable design investment there is no need to invest in designing Interlaken interfaces as pre-tested and verified implementations are already available that can easily be integrated into chip designs Comcores Intellectual Property (IP) blocks can be used in both FPGA and ASIC designs and provide all the configurability and scalability that Interlaken is designed to deliver Comcores Interlaken IP can be used for a variety of applications making it a valuable investment that not only

to deliver up to 2.6 Tbps per interface in both directions The width of the SerDes interface can be configured from 10-bit or 67-bit interface widths An application interface is provided based on the ARM® AMBA® Credited eXtensible Stream (CXS) interface The advantage of AMBA CXS as an application interface is that it is designed to support wide interfaces that can transfer packets at high data rates This enables multiple packets to be merged into a single transfer if required The Comcores Interlaken controller IP can be configured to support various application interface widths of 256 The number of interface segments can also be configured to be either 2 The Comcores Interlaken controller IP supports a variety of management interfaces to enable support for various chip designs and platforms: To enable fast time-to-market and ease of integration Comcores provides extensive documentation and a simulation environment with test cases and test scripts This includes a hardware test environment as well as RTL testbenches The current hardware test environment is based on a Xilinx Virtex-UltraScale VCU108 board (xcvu095-ffva2104-2-e) with External FMC loopback card This enables two primary test cases to be implemented: Click to enlarge Figure 6: Comcores Interlaken IP Core FPGA-based Test Environment data center processing workloads and data network capacity needs to grow to meet demand the challenge for today’s data centers is that low-cost-per-bit is no longer a sufficient performance goal Low-power-consumption-per-bit is just as important Raw speed and capacity are no longer enough; they need to be delivered with low power consumption This is forcing system and chip designers to re-think their approach Instead of relying on CPUs as the main processing engine while there is an increase in the number of application-specific dedicated data processor solutions Open RISC-V designs are now also available including chiplets for integration in chip packages SoC designs and disaggregated chip designs combining multiple optimized chiplets are also becoming more popular in an effort to meet stringent cost The common theme is a need to optimize how data is processed at every stage to ensure that an optimal system solution can be provided Interlaken provides the ideal chip-to-chip interface to address these needs As a highly configurable and scalable solution that is agnostic of the underlying physical implementation and whether the chip is FPGA or ASIC based Interlaken can be optimized to meet the specific needs of modern system and chip designers Interlaken provides the further advantage of reuse in multiple applications and across platforms With the Comcores Interlaken IP Controller highly configurable IP block that can be quickly and easily integrated as well as verified with expert support throughout the process For more information on Comcores packaged IP solutions and access to Comcores Interlaken IP core visit: www.comcores.com or contact us at
