[SignalTap] Hot to trigger on the NOT condition

[amildm]

Hi All,

I have a 16-bits bus added to SignalTap.

So, what conditions should I set in the SignalTap so that it will be triggered on any value on the bus, which is different from 0x5555?

Thank you!

Hmm, never thought about doing that.  I guess you should check if there is a NOT object when building an Advanced Trigger.  Or you could create an advanced trigger that ORs <0x5555 and >0x5555 comparisons.

Or you could create 2 trigger conditions.  The first one would be a basic AND trigger for 0x5555.  In the second trigger condition column, you'd set each bit to look for "either edge" transitions so the logic analyzer would ultimately trigger any time a bit switched away from 0x5555.

May I know does the suggestion from sstrell helps?
