DN9000K10PCIe-4GL
Xilinx Virtex-5 Based ASIC Prototyping Engine
Overview
The DN9000k10PCIe-4GL is a complete logic emulation system that enables ASIC or IP designers a vehicle to
prototype PCIe-based logic and memory designs for a fraction of the cost of existing solutions. The
DN9000k10PCIe-4GL is hosted on a 4-lane PCIe bus, but can be used stand-alone and configured via USB and/or
Compact FLASH. A single DN9000k10PCIe-4GL configured with 6 Xilinx Virtex-5, XC5VLX330's can emulate
up to 12 million gates of logic as measured by LSI (or at least how LSI used to measure ASIC gates when they
manufactured ASIC's). This number does not include the embedded memories and multipliers resident in each
FPGA, all of which are 100% available to the user application. The DN9000k10PCIe-4GL achieves high gate
density and allows for fast target clock frequencies by utilizing FPGA's from Xilinx's Virtex-5 FPGA family for
logic and memory. All FPGA resources are available for the target application. Any subset of FPGA's can be
stuffed along with any combination of speed grades.
Virtex-5 FPGAs from Xilinx
The DN9000k10PCIe-4GL uses high I/O-count, 1760-pin, flip-chip BGA packages from the 銑X・family. A
Genesys Logic GL9714 PHY device provides the PCI Express interface. Virtex-5 GTP "RocketIO" is not used. For
PCIe applications the user must supply a 1-lane or 4-lane PCIe core in FPGA A. A PCIe power cable is necessary
(provided) since a 4-lane PCIe connector cannot provide enough power to satisfy the current-hungry LX330's.
Abundant fixed interconnects (either differential or single-ended) are provided between the FPGA's. All pins of all
banks of each FPGA are utilized. FPGA to FPGA busses are routed and tested LVDS, run 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 160-pin main bus (MB) is connected to all FPGA's including the Spartan
configuration FPGA.
Daughter cards
Three 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 (900 Mb/s). Clocks, resets, and
presence detection, along with abundant power are included in each connector.
Memory
Six separate DDR2 SODIMM sockets are stuffed and have connections to FPGA's A, B, D, F, and C (two separate
sets). Each socket is tested to 250MHz with a DDR2 SODIMM. Standard, off-the-shelf DDR2 memory DIMM's
(PC2-4200 or better) work nicely and we can provide these for a small charge. We have developed alternative
SODIMM's that can be stuffed into these positions. Consult the factory for more details, but the list includes
FLASH, SSRAM, QDR SSRAM, mictors and other
Easy Configuration Via CompactFLASH or USB
The configuration bit files for the FPGA's are copied onto a CompactFLASH 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 LED's provide instant status and operational
feedback. As always, reference material such as DDR2 SDRAM controllers, and flash controllers are included (in
Verilog, VHDL, C) at no additional cost.
Status LEDs, Debug
Although no animal testing was performed, sophisticated statistical models are showing that the 130 status LED's
is enough to tan a small laboratory giraffe. These LED's are user controllable from the FPGA's so can be used as
visual feedback in addition to the lab giraffe-tanning application (LGTA). A JTAG connector provides an interface
to Chipscope and other third party debug tools. Other FPGA debug solutions will be available later in ・7.
