13.1 CORE Generator - "Upgrade and regenerate" process fails to regenerate


For a specific set of IP cores, the "Upgrade to latest version, and Regenerate" process does not complete.


Open the project in 13.1 CORE Generator software for Spartan-6 FPGA GTP Transceiver Wizard v1.5, the options are available to upgrade IP version and regenerate.

The two upgrade options are:

  • "Select Upgrade version, and Regenerate (Under Current Project Settings)"
  • "Upgrade to latest version, and Regenerate (Under Current Project Settings)"

For this core, the upgrade appears to work correctly as the following files are modified: .xco, .cgc, .gise, .txt and .tcl. However, the core is not regenerated (i.e., no new NGC file is delivered, no new example design etc.).

Is this expected behavior? What can be done to correct the problem?


This issue applies to the following set of cores:
  • Spartan-6 FPGA GTP Transceiver Wizard

To work around the issue, after upgrading the core files mentioned above, it is necessary to run "regenerate" separately.You can do this byeither using the"Recustomize and Generate" (Under Current Project Settings) or "Regenerate" (Under Current Project Settings) options.

This problem is fixed in ISE Design Suite 13.2.
