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
2. Specify a file to save the information to under “To File:”.
3. Click Generate and Save to File.
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.
