The DN2076k10 is a complete logic prototyping system that enables ASIC or IP designers to prototype logic and memory designs for a fraction of the cost of existing solutions. The DN2076k10 is a stand-alone system and can be hosted by 4-lane PCIe cable (GEN1), USB or Ethernet. A single DN2076k10 configured with 6 Xilinx Virtex-6, LX760s and 1 LX550T can emulate up to 37 million gates of logic as measured by a reasonable ASIC gate counting standard.  This gate count estimate number does not include embedded memories and multipliers resident in each FPGA. One hundred percent (100%) of the Virtex-6 FPGA resources are available to the user application. The DN2076k10 achieves high gate density and allows for fast target clock frequencies by utilizing FPGAs from Xilinx's 40nm Virtex-6 family.  Any subset of FPGAs can be stuffed and we can accommodate any combination of speed grades in any FPGA position.

Virtex-6 FPGAs from Xilinx

The DN2076k10 uses high I/O-count, 1759-pin and 1760-pin flip-chip BGA packages. The largest device, the LX760 in the FFG1760 package, has 1200 I/Os.  All are utilized.  Abundant fixed interconnects (either differential or single-ended) are provided between the FPGAs.  FPGA to FPGA busses are routed, tested, and characterized LVDS and run at 650MHz+ (which is 1.3 Gb/s when used in DDR mode and assumes -2 speed grade).  Single-ended at the reduced speed of 225MHz is characterized and tested. Example designs utilizing the integrated I/O shift registers (ISERDES/OSERDES) with DDR for pin multiplexing are included.  Each FPGA has a 50A VCCINT power supply.

A 52-pin Main Bus connects each of the six large FPGAs (MB[51..0]) to each other and the configuration FPGA (Config FPGA).  The connection to the Config FPGA allows for data movement via USB, Ethernet, PCIe and SATA to any/all FPGAs via the Marvell MV78200 processor.  100% of the resources of the Virtex-6 FPGAs are dedicated to the user application.

Two possible Virtex-6 FPGAs can be stuffed in the A, B, C, D, E, and F positions.  You are free to mix and match any FPGA with any available speed grade for each position from the following list (fastest to slowest):

  • LX760T-2,-1,-1L
  • LX550T-2,-1,-1L

Five possible Virtex-6 FPGAs can be stuffed in the G position. You are free to select a single FPGA in any speed grade from the following list (fastest to slowest):

  • LX550T-2,-1,-1L
  • SX475T-2,-1,-1L
  • SX315T-3,-2,-1,-1L
  • LX365T-3,-2,-1,-1L
  • LX240T-3,-2,-1,-1L

The maximum density stuffing option combines six LX760s with a single LX550T.  When stuffed in this fashion, DN2076k10 is capable of prototyping >37 million gates of ASIC logic with plenty of resource margin.  Of note is the SX475T, which contains a whopping 2,016, 25x18 multipliers per FPGA.  With an SX475 stuffed in the G position, a mere 500k gates of emulation logic is lost, but a whopping 1152, 25x18 multipliers are gained.  The SX475 is excellent at handling the DSP-heavy portions of your ASIC prototyping.

The Marvell MV78200 Discovery™ Dual CPU

A MONSTER for data movement and manipulation

Easy FPGA configuration is a required feature of large, multi-FPGA boards.  We use an onboard CPU to handle this function.  We chose a Marvell MV78200 from the Discovery™ Innovation CPU family.  Bluntly stated, this CPU is massive, massive overkill for the mundane task of FPGA configuration.   The MV78200 comes in a variety high performance interfaces, and all can be utilized to your advantage.

Dual Sheeva™ CPUs, 1GHz with floating point

And after we are done configuring the FPGAs we dedicate both CPUs to your application.  The CPUs in the MV78200 are Marvell Sheeva™ cores, which are ARM v5TE compliant.  The CPUs are clocked at 1GHz and each processor has a single and double precision floating point unit.  A fixed 1 GB, DDR2 memory is standard and is useful for large amounts of high speed data buffering.  The memory is organized as 128M x 64 and clocked at the full frequency allowed:  400MHz (800 MHz effective with DDR).  This DDR2 bank is shared between the two CPUs.  Boot code is resident in an SPI Flash, and application code is downloaded via any port:  PCIe, USB, and Ethernet.  We ship Linux as the standard operating system.  Options exist for VxWorks and other real-time operating systems.  Contact the factory for more information.

PCI Express

The Marvell 78200 acts as a two-port high-speed PCI Express switch (2.5Gbs). It connects all seven user FPGAs at 4-lane PCI Express speeds to a host computer. The Marvell 78200 has multiple DMA engines to pump data to and from any port. The user interface on the FPGA is a simple-to-use, pipelined A/D bus running at 6.4Gb/s. Drivers for data movement to and from a host machine are provided. A simple example FPGA design and host computer application streaming data at PCI Express x4 bandwidth to all seven FPGAs are provided.

Two Serial-ATA Ports (SATA II)

The MV78200 has two Serial-ATA Generation 2 (SATA II) ports, each capable of running at 3.0 Gb/s.  SATA is intended for high speed data transfer to/from serial-ATA hard drives.   Two SATA connectors are provided, allowing for direct, high-speed interfacing to external hard drives.  The MV78200 has specialized enhanced DMA (EDMA) engines for HDD data transfer with 512-byte buffer for each channel.  Examples of all possible data movement options, with source, are included.
