Tracing until the processor halts
Tracing until the processor halts
If you are using a state analyzer, you can begin a trace, run the
processor, then manually end the trace when the processor has halted.
To halt the processor, you can set a breakpoint using the Emulation
Control Interface or a debugger.
Some possible uses for this measurement are:
• To store and display processor bus activity leading up to a system crash.
• To capture processor activity before a breakpoint.
• To determine why a function is being called. To do this, you could set a
breakpoint at the start of the function then use this measurement to see
how the function is getting called.
This kind of measurement is easier than setting up an intermodule
measurement trigger.
To capture a trace before the processor halts
1 Set the logic analyzer to trigger on
2 Set the trigger point (position) to
3 In a logic analyzer window, click
4 In the Emulation Control Interface or debugger click
5 When the emulation module halts click
window to complete the measurement.
This is the recommended method to do state analysis of the processor
bus when the processor halts.
If you need to capture the interaction of another bus when the
processor halts or you need to make a timing or oscilloscope
measurement you will need to trigger the logic analyzer from the
emulation module (described in the next section).
