ContributorCyclone IV GX project failed migration from 18.1 to 20.1
As per title, I decided it was time to migrate an old project from Quartus 18.1 to 20.1. It's a Cyclone IV GX PCIExpress design and on compilation I get the errors:
Error (12252): Altgx_internal: e...
Hi,
Can you try to copy the following directory from 18.1 into same location in whatever newer release(20.1 and 21.1):
\18.1\ip\altera\ip_compiler_for_pci_express

Regular ContributorHi,
We do not recommend direct migration as some feature might be miss match.
I suggest you to regenerate a new design using Quartus v20.1.
Alternatively, you can try below KDB and see if it is able to resolve your problem or not.

ContributorSo I tried regenerating the design, no joy, same error.
The KBD mentions the same error code but with a different error message, so no help there.
Still stuck unfortunately.
