Hi zfs,

Sorry for the delay,

1. May I know which Quartus Prime are you using ?
2. Can you provide me your testbench for us to better debugging your issue ?

For your information, we are no longer supporting Modelsim. For the workaround, you may use our Intel QuestaSim for running the simulation. Link as provided below :

Thank you in advance

hi  hubert 

I apologize for seeing the message now.

The issue has already been resolved, and it had nothing to do with the software version.

It was a problem with the PLL signal

Hi zfs,

Can we request some of the information from you as above ?

Thank you in advance
