ISE: Cleanup Project Files

Is there heuristic or simple guidance on when to Cleanup before Generating Programming file?
ie in the past I generally do not, except at major waypoints.

this morning had an issue editing value of variable,
ISE spotted edit, generated 'new' .bit file,
but in actuality the outcome was not as expected,
rather as before edit.
After Cleanup same edit produced expected outcome.

  • We encountered the same issue several time and it sometime appears that even using the "Project -> cleanup project files" would not change anything ... only rebooting ISE would work (its very rare though).

    In Project there is event a "Force hierarchy reparse" menu that will force the tool to reparse all HDL files.

    I don't have general guidance on when to cleanup before re-build, but what i do is only to cleanup when i don't get the expected result ... just as you did ...
