Quartus 22.4 crash "Internal Error: Sub-system: VRFX2, File: /quartus/synth/vrfx2/vrfx2_xmr.cpp"

[mpr90]

When running synthesis on a design that synthesizes (and compiles) fine under Quartus Prime 19.2, I consistently get the following crash happening. It also crashes similarly under Quartus 23.1. Any ideas please?

Hi,

Do you mind attach the qar for me to replicate?

Need the design for further investigation.

Small design to replicate would be better.

[mpr90]

Hi, I'm afraid I can't share the design as-is. Whilst it may be possible with some effort to reduce the design size and remove IP to allow sharing/reproduction, I'd like to know please if there are other things that I can do to gather forensics that may help to identify the culprit in this crash?

[SyafieqS]

Internal error is normally a tool issue (most of it).

Thus, will be better if you can create small design replicating the error for further debugging.

[SyafieqS]

Also, have you tried on 23.1 Pro?

Thus that resolve the issue?

Please let me know, otherwise I will need the small test case for investigation.

[mpr90]

Running under Quartus 23.1 Pro had similar results: it also crashed.

It will take some time to get a test case together due to many other priorities, but I'll come back when I have one.

Let me know if there is any update from previous reply
