signaltap much be connected to a clock, and you can set it to trigger on a certain condition. Could you not just set it to wait until the counter is 0? if it doesnt capture enough time you will need to re-compile with a larger window.

If you need some more complicated trigger conditions, it is much easier to generate the trigger logic in HDL, use syn_keep and noprune attributes on them and then connect them into signaltap.
