Chapter 9: Using the Analysis Probe and Emulation Module Together
Triggering the Logic Analyzer from the Emulation Module
If you are going to run the emulation module from Reset you must do a
Reset followed by Break to properly set the breakpoints. The Reset
will clear all on-chip hardware breakpoint registers. The Break
command will then reinitialize the breakpoint registers. If you are using
software breakpoints which insert an illegal instruction into your
program at the breakpoint location you will not need to do the Reset,
Break sequence. Instead you must take care to properly insert your
software breakpoint in your RAM program location.
5 Click
Group Run
6 Click in the Emulation Control Interface or use your
Run
debugger to start the target processor running.
Clicking Group Run will not start the emulation module. The
emulation module run, break, step, reset are independent of the Group
Run of the analyzers.
7 Wait for the Run Control window in the Emulation Control
Interface or the status display in your debugger to show that the
processor has stopped.
The logic analyzer will store states up until the processor stops, but
may continue running.
You may or may not see a "slow clock" error message. In fact, if you are
using a state analyzer on the processor bus the status may never
change upon receiving the emulation module trigger (analysis arm).
This occurs because the qualified processor clock needed to switch the
state analyzer to the next state is stopped. For example, the state
analyzer before the arm event may have a status of "Occurrences
Remaining in Level 1: 1" and after the arm event it may have the same
status of "Occurrences Remaining in Level 1: 1"
8 If necessary, in the logic analyzer window, click
the measurement.
If you are using a timing analyzer or oscilloscope the measurement
should complete automatically when the processor halts. If you are
using a state logic analyzer, click Stop if needed to complete the
measurement.
