Chapter 6: Making Coordinated Measurements
Starting/Stopping Multiple Emulators
When you enter a normal trace command, trace at execute is disabled, and the
analyzer ignores the CMB EXECUTE signal.
Examples
To enable synchronous measurements from the transfer address:
specify run from transfer_address
To trace from an address when synchronous execution begins:
specify trace after address 10h
To start synchronous measurements
• Enter the cmb_execute command on the command line.
The cmb_execute command will cause the emulator to emit a pulse on the
EXECUTE line, thereby initiating a synchronous measurement. You do not have to
enable CMB interaction to use the cmb_execute command because by enabling
CMB interaction, you are only specifying how the emulator will react to the CMB
EXECUTE signal.
All emulators whose CMB interaction is enabled will break into the monitor when
any one of the emulators participating in the synchronous measurement breaks to
its monitor.
To disable synchronous measurements
• Enter the specify run disable command on the command line.
You can disable the emulator's interaction with the CMB by using the specify run
disable command. When interaction is disabled, the emulator ignores the CMB
EXECUTE and READY lines.
