98 MPC8240 and MPC8260 Emulation
Chapter 7: Using the Analysis Probe and Emulation Module Together
Triggering the Emulation Module from the Analyzer
The emulation module is now set to stop the processor when the logic
analyzer triggers.
3
Click
Group Run
in the Source window (or other logic analyzer
window).
4
If your target system is not already running, click
Run
in the
emulation Run Control window to start your target.
See Also See the online help for your logic analysis system for more information
on setting triggers.
To minimize the “skid” effect
There is a finite amount of time between when the logic analyzer
triggers, and when the processor actually stops. During this time, the
processor will continue to execute instructions. This latency is referred
to as the skid effect.
To minimize the skid effect:
1
In the Emulation Control Interface, open the Configuration
window.
2
Set the JTAG clock speed to the maximum value which your
target can support.
The amount of skid will depend on the processor’s execution speed and
whether code is executing from the cache. See page 74 for
information on how to configure the JTAG clock speed.
