SignalTap -> Trigger Conditions -> how to OR between them?

Hi All,

In SignalTap, there is an option to define several Trigger Conditions.

As for my understanding, these conditions are AND'ed - the trigger occurs only when all the conditions are met.

But could these Trigger Conditions be OR'ed (trigger occurs only when one of the conditions is met)?

Thanks!

    Oh, I didn't see you were going outside the range. Yeah, you'll need to use a state-based trigger to do that: "if condition1 or condition2" I think would work in a state.

    In the trigger condition column, choose that option from the pop-up list at the top (Basic AND, Basic OR, Comparative, or Advanced are listed there).

      As for my understanding, the BASIC AND works between the signals in the same column (trigger condition), I mean vertically. But how can I OR between the "horizontally" defined conditions?

      Actually I'm asking about the OR operation between the signals in the adjective columns (adjective trigger condition columns).

      Please see the picture below - I'd like the trigger will occur either when a value of the pic_cnt is less than 960 or greater than 960.

      So, there are two trigger condition columns... How can I OR between these condition columns (logical OR)?

        A single comparison trigger can do this with the interval check option. Right-click the cell and select compare and then interval check. You set upper and lower limits. But to interact between multiple columns, you have to use a state-based trigger. Otherwise, columns are checked in order in the sequential flow.
