Please advise how to change Time Units in SignalTapII.

The problem is that fore any Time Units being set the waveforms remain the same. In the attached pictures you can see the same waveforms for Time Unit=1ps and 1s. Input clock is 50Mhz. The design is from the above tutorial. What am I doing wrong or is it a bug in SignalTapII?- Mark as New

I am working with SignalTapII, not Timequest.

I dont need to sample signals at a different frequency, its just a simple 8-bit counter example with 50MHz clock input. I just want to set any valid Time Unit to__see the length of the pulses in ns/ms__, but I have the above problem. Only Sample Numbers mode ( just giving the number of the counted pulses ) is working correctly.

Sorry I meant SignalTap, not Timequest.

To be honest I've never used the timeunits. I've always counted the number of samples between two events and multiplied myself by the clock period.- Mark as New
