11.3, 11.4 iMPACT - PROM File Formatter does not accept Spartan-6 Automotive FPGA bit files


PROM File Formatter does not accept Spartan-6 Automotive FPGA bit files; when I add the files, the following message occurs:

"The specified file is not Spartan-6/Spartan-3E/3A/3AN or Virtex5/Virtex6 file. Please select another file"

How do I generate my PROM programming file?


To work around this issue, use the promgen tool from a command prompt. Following are example command lines:

SPI flash

promgen -w -p mcs -c FF -o <output_file> -s <flash density> -u 0000 <input_file>.bit -spi

BPI flash

promgen -w -p mcs -c FF -o <output_file> -s <flash density> -u 00000000 <input_file>.bit -bpi_dc [parallel/serial]

For further details on promgen switches, consult the "Command Line Tools User Guide": http://www.xilinx.com/support/documentation/dt_ise11-1.htm

This issue is scheduled to be resolved in iMPACT 12.1.
