I have tried using the Xilinx ngc2edif convertor but when I tried to
generate a bit file from the edf file its says:
ERROR:NgdBuild:766 - The EDIF netlist 'synthetic2.edf' was created by the
Xilinx
NGC2EDIF program and is not a valid input netlist. Note that this EDIF
netlist is intended for communicating timing information to third-party
synthesis tools. Specifically, no user modifications to the contents of
this
file will effect the final implementation of the design.
ERROR:NgdBuild:276 - edif2ngd exited with errors (return code 1).
ERROR:NgdBuild:28 - Top-level input design file "synthetic2.edf" cannot be
found
or created. Please make sure the source file exists and is of a
recognized
netlist format (e.g., ngo, ngc, edif, edn, or edf).
