Cross-Arming Trigger Examples
To monitor two coprocessors in a target
system
Debugging coprocessor systems can be a complex task. Replicated
systems and contention for shared resources increase the potential
problems. Using two state analyzers with analysis probes can make it
much easier to discover the source of such problems. For example, you
may want to set up one analyzer to trigger only when a certain problem
occurs, and set up the other analyzer to be armed by the first analyzer
so that it takes its trace only when the first analyzer recognizes its
trigger. This will let you observe the behavior of both coprocessors
during the occurrence of a problem.
1 Set up both analyzers as state analyzers.
2 Go to the first analyzer’s Trigger menu.
3 Set the second analyzer to be run from the first analyzer.
4 Turn on Count Time.
5 Set the first analyzer to trigger on the problem condition.
Some problems may involve complex sequences of conditions. See
earlier examples in this chapter for more information on defining
trigger sequences.
6 Go to the Trigger menu of the second analyzer.
