Critical Issue
Description
In Quartus Prime Pro Edition software version 16.0, Project > Clean Project is not compatible with Project > Import Design. If you run Import Design, the project will fail with Error(23035):
Tcl error: ERROR: Cannot open project: aram.
Resolution
To workaround this issue:
- Do not use Project > Clean Project with Project > Import Design. Instead, use the Overwrite option from the Import Design menu or command line argument.
- If Clean Project was called, you can select Close project followed by Open project in the GUI before calling Import Design; this fixes the invalid state.
