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

Hubert

    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
