SignalTap II - waiting for clock

$

Hi,

I'm attempting to use SignalTap II to verify my design is running correctly. I have set the SignalTap signals to be from pre-synthesis to prevent my desired signals from being optimised out. I have set my acquisition clock to be the same clock that drives the changes in my output data. I believe this clock is used in the design correctly because I checked Assignment Editor and found the little 'Status: OK' notification for the signal. My output signal names are black (not red) and and my clock name is also black (not red), and the stp file appears in the project files. In compilation settings, SignalTapII is enabled and points to the correct .stp file. So everything appears to be in working order. However, when I compile and then program via JTAG, I get the 'ready to acquire' notification. I run analysis and then status of the auto_signaltap_0 instance says 'waiting for clock'. My understanding is that means my acquisition clock is not cycling correctly, but I don't know how this can be if the clock in Assignment Editor is confirmed to be OK and found in the design. Because SignalTapII is waiting for the clock to cycle, I guess nothing is triggering at all. Is this a problem with my SignalTap II setup, or my entire project? I know my logic works as I simulated it in ModelSim.

Thanks for your time.
