Chapter 3 Advanced Use of ID78K0 3.1 Verifying the Validity of Evaluation
67
3.1.2 Verifying the Validity of Evaluation Based on Coverage
Ideally, all possible patterns of program execution should be evaluated. Due to time or other
restrictions, however, evaluation may have to be restricted by, for example, sampling and
combining several patterns. Evaluation based on sampled patterns must, however, be checked
for validity.
One method of verifying the validity of evaluation is the use of the coverage results to check
whether all instructions have been executed.
The above check can easily be performed by using the Coverage window and the memory map
in the link list file (.MAP), output upon linkage of the program.
Verification based on coverage
1.
Refer to the memory map in the link list file to identify any free spaces (* gap *) in the program.
2.
Refer to the contents of the Coverage window to check whether all memory spaces other than the
free spaces, identified in step 1, have been accessed (read, written, or fetched).
3.
If any unaccessed space is revealed by step 2, check the program and review the evaluation items.
If any free space in the program has been accessed, check that space by, for example, setting
event conditions.
