7.1i BitGen - "Fatal Error: Bitgen: Bs_Bitgen.c: 344:"


General Description:

Running the Generate Programming File process from Project Navigator results in the following error:

"Fatal Error: Bitgen: Bs_Bitgen.c: 344:"


This problem might occur when "Generate Simulation Model" is run as part of Place and Route (PAR). In this case, a dummy ".ncd" file is created by Project Navigator as a place holder to track the status of the design implementation. The dummy ".ncd" file is incorrectly sent to the Generate Programming File process (bitgen) which generates the error.

PAR needs to be re-run to generate a correct ".ncd" file.

This problem has been fixed in the latest 7.1i Service Pack available at:

The first service pack containing the fix is 7.1i Service Pack 2.
