Acquiring Code Coverage
The emulator acquires code coverage information (C0 coverage) from the address range specified
by the user and displays the results.
Notes: 1. The information on the executed delay slot cannot be acquired.
2. Be sure to set the following when using the code coverage function:
• [Acquisition] dialog box that is opened by selecting [Set] from the popup menu of
the [Trace] window:
[Trace type]: Select [AUD Trace].
[Trace Extend Mode]: Uncheck the [Trace data with PPC] check box.
• Ch12 of the [Eventpoint] window:
[Branch event] sheet: check all the branch conditions.
[Action] sheet: Check [Acquire trace].
These settings above are default when the emulator is activated.
3. In this function, the data that is output by AUD trace is used. Accordingly, when the
emulator is used in realtime trace mode, the trace data may be lost and the code
coverage information will not be collected normally. In such a case, it is recommended
to use the emulator in non-realtime trace mode.
By default, the emulator is activated in realtime trace mode.
