Simulation Fails with PLL Clocks Out of Synchronization for UniPHY External Memory Interfaces


During simulation, the PLL clocks lose synchronization.


To work around this issue, follow these steps:

  1. In text editor open the design file and remove the following line: coverage exclude_file
  2. In the ALTPLL MegaWizard interface, turn on Create output files using the Advanced PLL parameters and regenerate the PLL ().
