3. DMA engine example design for ML505 es silicon and ML555 production silicon
3.1 Place and Route: run the implement.sh script
[Token2000@LinuxWS01]$cd ~/DMA_Freeware/pcie_ml505esx1_prj/ml505cg/endpoint_blk_plus_v1_5/implement/
[Token2000@LinuxWS01]$source implement.sh
** NOTE: Before P&R, check you have installed ISE9.2.3 with IP update2. Also,
** NOTE: you may need to register for a free PCI express IPcore license from www.xilinx.com
3.2 Simulation: run the simulate_mti.do script
[Token2000@LinuxWS01]$cd ~/DMA_Freeware/pcie_ml505esx1_prj/ml505cg/endpoint_blk_plus_v1_5/simulation/novas
[Token2000@LinuxWS01]$vsim &
In modelsim, "do simulate_mti.do"
** NOTE: Before simulation, check you have installed modelsim 6.x.
** NOTE: To setup Xilinx simulation library, check sim.pdf in ISE9.2 directory.You can use following command line.
** [Token2000@LinuxWS01]$compxlibgui &
** NOTE: Verdi (debussy) is for waveform browsing, if do not installed. You may remark following lines from board.v
** initial begin
** $fsdbDumpfile("bmd.fsdb");
** $fsdbDumpvars;
** end
4. Windows Driver and Application software
4.1 Compile Windows driver: open a command line window from Microsoft WDK.
D:\> cd D:\DMA_Freeware\pcie_software\PCIE
D:\> bld
** NOTE: Before Compile Windows driver, check you have installed Microsoft WDK Build 6001 16549
4.2 Compile Windows application software:
D:\> cd D:\work\PCI\PCIEBoardTest (assuming it is the software home directory)
open PCIEBoardTest.vcproj with Microsoft VS2005, then build it.
** NOTE: Before Compile Windows driver, check you have installed Microsoft Visual Studio 2005
5. Run DMA demo on ML505/ML555
5.1 Run DMA demo on ML505 (ES silicon):
I. download ml505_pcie_x1_plus_design_creation.pdf from Xilinx.com. Set boot from SYSACE CFG6.
II. copy DMA_Freeware\pcie_ml505esx1_prj\ml505cg\endpoint_blk_plus_v1_5\implement\pcie_x1_plus_v1_5es_imp.ace into CF6 postion of CF card
III. According to ml505_pcie_x1_plus_design_creation.pdf, setup ML505 in your PC.
IV. Power on, when windows ask for driver, assign to DMA_Freeware\pcie_software\driver\PCIE.inf
V. After driver installation. run DMA_Freeware\pcie_software\run\PCIEBoardTest.exe for a test.
** NOTE: Make sure your PC have been 100% power-off, before plug or unplug ML505/ML555.
5.2 Run DMA demo on ML555 (production silicon):
I. download ug201.pdf from Xilinx.com. Set JUMP to boot from XCF32P U1, REV0. Set PCIE switch.
II. Burn DMA_Freeware\pcie_ml555x4_prj\ml555cg\endpoint_blk_plus_v1_5\implement\ml555xcf32p.mcs into XCF32P U1.
Detail steps is in "Programming the PROM" section of ug201.pdf
III. According to ug201.pdf, setup ML555 in your PC.
IV. Power on, when windows ask for driver, assign to DMA_Freeware\pcie_software\driver\PCIE.inf
V. After driver installation. run DMA_Freeware\pcie_software\run\PCIEBoardTest.exe for a test.
** NOTE: Make sure your PC have been 100% power-off, before plug or unplug ML505/ML555.
6. DMA Performance
Performance Screen shots can be found at DMA_Freeware\pcie_software
screenshot_X1.jpg, screenshot_X4.jpg, screenshot_X4_read.jpg, screenshot_X4_write.jpg
The PC platform is DELL GX280 (Intel 915G chipset). GX280 is the cheapest PC I can found.
I got 218MBps(W)/172MBps(R) on ML505 PCIx1, 445MBps(W)/683MBps(R) on ML555 PCIx4
You may get better performance on new PC (INTEL 965G/P35/3000X/5000X chipset) than my old GX280. :)
7. Technical Support
