Cyclone IV ModelSim gate level simulation accuracy

I have a Cyclone IV design that shows different timing results in a ModelSim gate level simulation as compared to the Timing Analyzer results. For some output pins the Timing Analyzer shows about 600...

    Hi Nuno,


    Assuming your verification is timing, yes I would suggest you to use Timing Analyzer static timing analysis rather than gate-level timing simulation. Gate-level timing simulation of an entire design can be slow and should be avoided even though it supports your device


    Thanks,

    Regards
