The DN9002k10PCI is a complete logic emulation system that enables ASIC or IP designers to prototype logic and memory designs for a fraction of the cost of existing solutions. The DN9002k10PCI is hosted on a 32/64-bit, 33/66MHz PCI bus, or can be used stand-alone and configured via USB or Compact FLASH. A single DN9002k10PCI stuffed with 2 Xilinx Virtex-5, LX330s can emulate up to 4 million gates of logic as measured by LSI (or at least how LSI used to measure ASIC gates when they manufactured ASICs). This number does not include the embedded memories and multipliers resident in each FPGA, all of which are 100% available to user application. The DN9002k10PCI achieves high gate density and allows for fast target clock frequencies by utilizing FPGAs from Xilinx's Virtex-5 FPGA family for logic and memory. All FPGA resources are available for the target application. Any subset of FPGAs can be stuffed.

Virtex-5 FPGAs from Xilinx

The DN9002k10 uses high I/O-count, 1760-pin, flip-chip BGA packages. Abundant fixed interconnects (either differential or single-ended) are provided between the FPGAs. All pins of all banks of both FPGA are utilized. FPGA to FPGA busses are routed and tested LVDS, run source synchronously at 450MHz+ but can be used single-ended at a reduced speed. Example designs utilizing the integrated ISERDES/OSERDES with DDR for pin multiplexing are included. A 36-pin main bus (MB) is connected to both FPGAs including the Spartan configuration FPGA, allowing for data movement via USB.

Daughter cards

Two separate 400-pin FCI MEG-Array connectors allow for customization with daughter cards. Signals to/from these cards are routed differentially, and can run at the limit of the FPGA: 450MHz. Clocks, resets, and presence detection, along with abundant power are included in each connector.


A single DDR2 SODIMM socket is stuffed and is connected to FPGA B. The socket is tested to 250MHz with a DDR2 SODIMM. Standard, off-the-shelf DDR2 memory DIMMs (PC2-3200/PC2-4200) work nicely and we can provide these for a small charge. We have developed alternative SODIMMs that can be stuffed into these positions. Consult the factory for more details, but the list includes FLASH, SSRAM, QDR SSRAM, mictors, DDR1, and others.

Easy Configuration Via CompactFlash or USB

The configuration bit files for the FPGAs are copied onto a Compact FLASH card (provided) and an on-board Cypress microprocessor controls the FPGA configuration process. FPGA configuration can also be controlled via the USB interface. Visibility into the configuration process is enhanced with an RS232 port. Sanity checks are performed automatically on the configuration bit files, streamlining the configuration process. FPGA configuration occurs at the fastest possible SelectMap frequency - 48MHz. Multiple LEDs provide instant status and operational feedback.

Other Cool Stuff

Many FPGA-controlled LEDs provide for visual status. Although no laboratory testing was performed, statistical animal models are showing this to be enough illumination to blind four very rare, endangered, slightly confused Pacific Northwest tree octopi (Octopus paxarbolis) A Mictor connector, which has 34 FPGA signals, enables observation via logic analyzers from Tektronix and HP.
