To look at control and status signals during execution
of a routine
The state analyzer will trigger on the start of the routine whose control and
status signals are to be examined more frequently than once per bus cycle.
When the state analyzer triggers, it sends out an arm signal. The timing
analyzer triggers when it receives the true arm level and detects the
transition represented by Edge1.
1
Set up one state analyzer and one timing analyzer.
2
Go to the state analyzer’s Trigger menu and define term R_START to
represent the starting address of the routine.
3
Under State Sequence Levels, enter the following sequence
specification:
•
While storing "anystate" TRIGGER on "R_START" Occurs "1" Else on "no
state" go to level "1"
4
Go to the timing analyzer’s Trigger menu.
5
Define the Edge1 term to represent a transition on one of the control
signals.
6
Set the timing analyzer to be run by the state analyzer. Under Timing
Sequence Levels, enter the following sequence specification:
•
TRIGGER on "arm
•
Edge1" 1 time
You do not need to use a combination trigger when one analyzer is armed
from the other analyzer - the arm term is ANDed automatically with the term
already in use.
