Code Coverage, Trace Memory, Real-Time Reads
7.3.3
Creating a Code Coverage Report
Code coverage information may be saved into a file using the controls in the “Code
Coverage Report” section of the dialog tab.
1. Preview the code coverage information by clicking Preview to determine if it is
what you want to save.
2. Specify a file to save the information to under “To File:”.
- For a new file, type in the file name and path or browse to a file location.
When you have reached the location at which you want the new file, type in
the file name and click Save .
- For an existing file, type in the file name and path or browse to a file and
location. To append this data to old data in the file, instead of overwriting it,
check the “Append to File” check box.
3. Click Generate and Save to File .

TRACE MEMORY
The trace memory window in MPLAB ICE 4000 contains information that is uploaded
from MPLAB ICE 4000’s trace buffer. The trace buffer consists of memory hardware
that can log the electrical state of the various device data, address and control signals
at an instruction cycle in real time as the device executes instructions. By default, all
instruction cycles are captured by the trace buffer. The Complex Trigger tab can be
used to control which instruction cycles are captured ( Chapter 6. “Complex and
Internal Triggers” ).
In MPLAB ICE 4000, the trace buffer captures data on a 216-bit wide analyzer that is
connected to the emulator chip and other devices in the emulator.
