To Trigger On Entry To A Function - HP 16500B User Manual

To trigger on entry to a function

This sequence triggers on entry to a function only when it is called by one
particular function.
Select the state analyzer Trigger menu.
1
Define the terms F1_START and F1_END to represent the start and
2
end addresses of the calling function. Define F2_START to represent
the start address of the called function.
Under State Sequence Levels, enter the following sequence
3
specification:
•
While storing "anystate" Find "F1_START" 1 time
•
While storing "anystate" TRIGGER on "F2_START" 1 time Else on
"F1_END" go to level 1
•
Store "anystate"
This sequence specification assumes there is some conditional logic in
function F1 that chooses whether or not to call function F2. Thus, if F1 ends
without the analyzer having seen F2, the sequence restarts.
The specification also stores all execution inside function F1, whether or not
F2 was called. If you are interested only in the execution of F1, without the
code that led to its invocation, you can change the storage specification from
"anystate" to "nostate" for the second sequence term.
