correctness. When the test is finished, every part of the entire program should have been executed. If any part
has not been executed, there is a possibility that the test is insufficient.
It can know what percentage of the entire program executed when the coverage function for the high-speed
version simulator debugger to have is used.
In addition, details such as which addresses were not accessed can be checked.
In this debugger, the range to measure coverage can be set.
Please set the time base range only to the code area when you do the C0 coverage.
Moreover, the access of the variable can be examined as the variable not used is searched out by setting the
time base range to the data area.
