SignalTapII question

Hello,

I'm having a little issue with signaltap. When I hit Run Analysis, the status flips between Offloading acquired data and Waiting for trigger but no waveform is displayed (it used to be - not sure what I've changed). When I hit in an empty area below my list of waveforms, the data gets updated, and so the log# is also changed, but I still have to click each and every time I want it updated.

Whether I use a trigger on a node or not, or I use segmented or continuous doesn't make a difference. Also starting from scratch with a new .stp file, deleting db/ and incremental_db/ doesn't help, so maybe it could be a software parameter? Couldn't find such thing in the documentation.

Thanks.

    The initial state should be not running.

    Assuming you actually start a single run (Run Analysis) and SignalTap is waiting for a trigger endlessly, then the trigger condition apparently isn't met. What happens, if you set no trigger at all?

    If I set no trigger and do a single run, it displays offloading acquired data for less than a second and goes back to not running. In this case, the waveforms get updated.

    Problem shows when I do an autorun, it indeed shows offloading acquired data and quickly flashing what I believe is waiting for trigger without stopping, only the waveforms don't get an update, and I'm confident at least some of them should change as I actually have a counter probed for testing this case.

    Solved. The Data Log check box was checked, however the Data Log window was not shown.

    Hello.

    We've got same problems with SignalTab II exept one thing. Sometimes, after some compilation SignalTab stop working. When I run acquiring (Single Run or Autorun) it shows message "Acquiring pre-trigger data" and hangs in that state. It doesn't mean if I choose trigger conditions or not chosen trigger at all. Restarting acquiring in signaltab doesn't solve problem.

    The only things that helps is changing project in some way - add/remove some probes in signaltab setup window and recompile project.

    Device: Stratix III EP3SL110F1152C2

    Quartus 9.1 sp2

    Windows XP SP3

    PS One compilation takes about 20-30 minutes, so it very boring to find that after some changes in project Signaltab not working. Please help!
