signaltap question trigger

I'm not sure I understand what you want to do, you seem to describe two different needs in your two paragraphs.

If the signals don't change at all after the hang up, you can just disable all the triggers in signaltap and do a single run. Then you'll see immediately the state of all your signals.

I don't remember if it is possible to capture the last time a trigger is active instead of the first one. You can try the "autorun analysis" function to capture data until you stop it, but I don't remember if it disables the triggers or not.
