Hello,

operating SignalTap in freerun mode, with no trigger condition defined is good to see, if signals give reasonable values. However, if a signal is displayed and has transitions in freerun mode, there's no reason why it shouldn't also work as a trigger.

Could it be, that you have overlooked an additional trigger condition, may be in a group?

Or if you have a trigger condition from several signals, it must not necessarily be ever true.

Regards,

Frank
