CORE Generator - "ERROR:coreutil:424" and "ERROR:sim:57" when using network drive


When I attempt to recustomize or generate a core from the CORE Generator tool, I receive the following errors:

"ERROR:coreutil - An internal error has occurred. To resolve this error, please consult the Answers Database at
ERROR:coreutil - Failure to generate output products
ERROR:coreutil:424 - An error occurred while running Java. Please examine the console or coregen log file for a specific IP related error.

For more information please search the Xilinx Answers Database for this error:
Finished Generating.

ERROR:sim:57 - Error found during generation"

Why is this happening?


This error occurs under the following conditions:

  • The CORE Generator project is using a UNC path to point to a network location rather than using a mapped network drive (the CORE Generator tool is not able to recognize the UNC pathname).
  • The CORE Generator project is in theroot directory levelon a mapped drive.

To resolve the issue, map the drive where the project exists and use a project directory other than theroot directory, then regenerate the core.
