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

Hi,

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.

So 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.
