How can I tell which bitfiles perform what functions on PCD and related boards?
EDT PCD boards are equipped with a “PCI Xilinx” which has the DMA engine used to transfer data to/from the host computer. The PCI Xilinx is loaded at power-up from a flash PROM on the EDT board so it is available as the system configures during boot. The flash PROM may be loaded by the program “pciload” which is described in the “PCI CD User’s Guide”. Changes to the flash take effect after the power to the computer is turned off and back on. A second Xilinx FPGA called the “Interface Xilinx” talks directly to the user’s equipment, and may be loaded at anytime by the program “bitload”. The “pcdrequest” program accepts menu selections to create a script to load the interface bitfiles. The PCI flash loaded determines which interface Xilinx bitfiles can be utilized on the PCI CD board. The dependencies listed here are used by the “pcdrequest” program. In the following listing, PCI Xilinx bitfiles are left justified.
