Problem Title:

2.1i COREGEN, C_IP4, VIRTEX, FFT:   "Generating the core will overwrite the following
[xdsp_xxxx.edn] files" when generating more than one FFT



Problem Description:
Urgency: standard

General Description:
A pop-up dialog titled "Overwrite Files" may be seen when generating more than one FFT in the same CORE Generator project directory. The full message text is:

     "Generating the core will overwrite the following files. Select "Overwrite Files" to
      overwrite the files or "Cancel" to abort.


Solution 1:

This should not be cause for concern.

The 16-point, 64-point, 256-point and 1024 point FFTs are built up using a hierarchy of common EDIF building blocks which all share the naming convention, "xdsp_xxxxxx.edn".

For all FFTs generated after the first one in a given project, you can expect to see a warning message like this. You should simply allow CORE Generator to overwrite the pre-existing .EDN files.
