2.1i COREGEN, C_IP4, VIRTEX, FFT: "Generating the core will overwrite the following [xdsp_xxxx.edn] files" when generating more than one FFT
Description
Keywords: overwrite, fft, virtex, c_ip4, coregen
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.
解决方案
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.
