12.x iMPACT - Can .exo file still be supported?


Xilinx has discontinued the .exo file in Prom File Formatter mode and Boundary Scan mode in the iMPACT 12.x GUI.

Do we have to go back to 11.x if we need to use .exo files?


Xilinx 12.x tool still supports .exo file formatting and programming with command line instead of GUI.

1, To generate an .exo file, use -p exo option in PROMGen. For example, (assuming the target device is XCF32P):

promgen -p exo -u 0 my_design.bit -x xcf32p

2, To program an .exo file into a PROM, use iMPACT batch mode. For example, (assuming the PROM is the first device in the JTAG chain) after entering iMPACT batch mode, run the following commands:

setmode -bs
setcable -port auto
assignfile -p 1 -file my_design.exo
program -p 1 -e -v
