General Description:
I am using a Forward Error Correction (FEC) core (or I am using the Xilinx System Generator v2.1) with the Xilinx 4.1i software. I am using the Reed Solomon Encoder or Decoder v2.0, Interleaver or Deinterleaver v1.1, or Viterbi Decoder v1.1. After updating my software to version 4.2i (4.1i Service Pack 4), my core does not generate (or does not work).

The following error messages are associated with this situation:

"Coregen.log - generate
Error: Internal error has occurred; to resolve this error please consult..."

"Error: Sim has a problem implementing the selected core.
Sim Generator implementation netlist will not be generated.
Sim Generator: failure of sim to implement customization parameters."

"Error: Did not generate impl. netlist edn."

"Error: The XSF symbol generation support file cannot be generated."


If you are continuing to use the versions of the above cores after installing the 4.2i software, you must download an updated zip file to enable the cores to work correctly. This file is available at:

Alternatively, you may download the newer versions of the cores from this same URL.

(NOTE: System Generator v2.1 users that are updating to 4.2i must download an updated version of the zip file for the Reed Solomon Encoder/Decoder v2.0, Interleaver/Deinterleaver v1.1, or Viterbi Decoder v1.1.)
