5 # Converts perfectly good EXT records from an XNF file to
6 # a .pcf file for the "par" step of the Xilinx toolchain.
7 # Why on earth is this needed? Oh, well, the joys of working
8 # with black-box-ware.
10 # Usage: xnf2pcf <design.xnf >design.pcf
12 # Refer to the resulting .pcf file in the invocation of "par", syntax:
13 # par [options] infile[.ncd] outfile pcf_file[.pcf]
15 # Tested (successfully!) with XNF from Icarus Verilog, see
16 # http://www.geda.seul.org/tools/verilog/index.html
17 # and Xilinx back end tools from Foundation 1.5
