configuration bit stream
Getting started with Xilinx XC3S200 /SX3S400 PFGAs
iMPACT is part of the free available ISE Webpack.
The version used here is ISE WebPack 8.1i.
The same applies to ISE WebPack 8.2i.
1. Install Xilinx
ISE WebPack 8.1i and 8.2i (Windows / Linux)
2. Configure XILINX FPGA Device without
Notice: In this mode the FPGA keeps configuration until reset or next power
Attach Xilinx JTAG Parallel Cable III to the parallel port.
Check correct detection under 'Output / Cable setup'.
Select Boundary Scan Mode from the right selection 'iMPACT
Modes' if not already done.
Execute 'File / Initialize Chain' to detect the devices in
the daisy chain.
Select the configuration bit stream to configure FPGA
with the context menu (right button) 'Assign New Configuration File'.
3. Generate PROM File for automatic FPGA configuration
with Flash after power up and reset:
Select PROM File Formatter from the right iMPACT Modes.
Select Edit / Launch Wizard.
Choose Xilinx PROM and PROM File Name.
Select XCF02S Flash and use 'Add' buttom.
Answer the question 'Would you like to add another device
file' with No.
Generate the PROM file with 'Operations / Generate File'.
change in Boundary Scan mode.
you can assign the newly created PROM file to the Flash.
After updating the flash the FPGA loads the configuration
bit stream from flash after power up or reset.
