QuestaSim - Fatal error simulating altpll-ip

Hi, I am trying to simulate design including the altpll-ip, but I get this fatal error: I have changed timescale to ps with no luck. Any suggestions?

Have you tried running the simulation using the NativeLink simulation flow?
Without the design files, it is challenging to debug and understand the root cause. If possible, creating a simplified design would help us investigate further.

Otherwise, the currently identified possible root cause is described in the KDB below, which I believe you have already reviewed:

No, I have not tried NativeLink simulation flow before. How is it done?

Changing to ps makes no difference.
