The Reference Design
This chapter introduces the DN9002K10PCI Reference Design, including information on what
the reference design does, how to build it from the source files, and how to modify it for
another application.
1 What the reference design does
1.1 Example usage of all interfaces
The reference design helps users by showing them how using each interface is possible. Code is
provided as-is, and is intended as proof-of-concept on each interface advertised for the
DN9002K10PCI product. The Dini Group warrants only that the DN9002K10PCI hardware is
functional and usable. The interfaces that the Dini Group design exercises and provides
examples for are:
•
Access to the DDR2 SDRAM Modules At 250Mhz
•
Known-good bitfiles for programming over USB, PCI, CompactFlash or JTAG
•
RS232 Communication
•
FPGA Interconnect, using IO Flip-flops
•
FPGA Interconnect using advanced source-synchronous techniques
•
High-Speed PCI (DMA mode to FPGA A)
•
Main Bus interface (for USB and PCI communication)
•
Main Bus memory-mapping example (to DDR2, block RAM)
•
Blink LEDs in cool patterns.
•
Reset Button
•
New internal Virtex-5 features (PLL, ODELAY, 550Mhz clocking, 800Mbs IO)
•
Daughter Card (Test module only)
•
Set global clocks
•
Ethernet
•
Mictor cable (for LVDS communication. Mictor also can be used for logic analyzers)
All source code for the reference design is included on the CD and may be used freely in
customer development. Precompiled bit files for the most common stuffing options are also
included and can be used to verify board functionality before beginning development. A build
