Chapter 7: Device Configuration 107
7.22.1 Using XTR
No special setup for XTR Record is required; XTR can be recorded by using the
appropriate automation commands as described in Section A.7.28, “XTR”, on page 253.
The XTR XML file can easily exceed five Gbytes in size. Please make sure you have
enough physical storage before you start XTR Record.
7.22.1.1 Recoding XTR Trace
To record XTR, please enter the following commands in the simulator‟s console window:
1 simnow> xtrsvc.xtrfile <filename.xml>
1 simnow> xtrsvc.xtrenable 1
1 simnow> go [or hit Run on the shell]
7.22.1.2 Stop XTR Record
To stop XTR record, please enter the following commands in the simulator‟s console
window:
1 simnow> stop [Stop the simulation]
1 simnow> xtrsvc.xtrenable 0
7.22.1.3 XTR Playback
For XTR Playback, XTR Northbridge (XTRNB) replaces all the devices including any
other Northbridge in the system. Hence for UP-XTR Playback, only AweSim and
XTRNB are required. Please refer to Section 7.22.1.3, “XTR Playback”, on page 107, on
how to connect AweSim and the XTRNB device. It is recommended to also include the
Debugger device for debugging or logging needs.
To playback XTR, please enter the following commands in the simulator‟s console
window:
