Triggering Examples
Single-Machine Trigger Examples
To trigger on the nth iteration of a loop
Traditional debugging requires print statements around the area of
interest. This is not possible in most embedded systems designs, but
the analyzer lets you view the system’s behavior when a particular
event occurs. Suppose that your system behaves incorrectly on the last
iteration of a loop, which, in this instance, happens to be the 10th
iteration. You can use the analyzer’s triggering capabilities to capture
that iteration and subsequent processor activity.
1Go to the state analyzer’s Trigger menu.
2Define the terms LP_START and LP_END to represent the start
and end addresses of statements in the loop, and LP_EXIT to
represent the first statement executed after the loop terminates.
3Change State Sequence Level 1’s function to "Find event2 n
times after event1 before event3 occurs."
4In the pop-up, enter the following sequence specification:
•While storing anystate Find "LP_START" "9" times a fter "LP_END" before
"LP_EXIT" occurs.
You should use your value for n-1 instead of "9" in the sequence
specification above.
