Trace function in simulator mode
324
In the simulator mode, you can specify trace function ON/OFF, display method, and write to a file. When
the trace function is turned on, the trace result is displayed on the screen or saved to a file every time an
instruction is executed.
The following lists the trace information that is displayed on the screen in simulator mode:
<1st line of each trace information>
<Lines 2–4 of each trace information>
These lines are displayed when register option is selected with the tm command.
The register values appear in the order shown below.
Trace information is displayed in the [Trace] window when display to the window is selected. If the [Trace]
window is closed, the information is displayed in the [Command] window.
When saving to a file is selected, the information is output to the file and is not displayed in the window.
Unlike in ICE mode, there is no need to input any specific command to display trace information. Trace
information is displayed automatically according to the successive execution or single-stepping of a
program.
The [Trace] window allows you to see trace information for the last 255 instructions. The trace information
for instructions beyond that are deleted.
