3.1.3 Notes on Coverage Results
When checking the coverage results, note the results of conditional branches.
The IE-78000-R-A supports C0 coverage, which cannot be used to check how processing has
branched at a conditional branch instruction.
Example of execution of a conditional branch instruction
1. When the following program is executed from address 80H to 8CH, a conditional branch instruction
is executed at address 86H. Execution jumps to address 88H because the condition is false.
Addr Data
0080 A101
0082 A302
0084 4D01
0086 BD02
0088 610B
008A A200 MOV C,#0H
008C 00 NOP
Mnemonic
MOV A,H ;
Assume that the H register contains 1.
MOV B,#2H
CMP A,#1H
BNZ
$8AH
ADD A,B
2.
The coverage results are as follows, indicating that all instructions have been executed.
All instructions at
addresses 80H to 8CH
have been executed.
3.
Actually, however, the condition may be true, depending on the stored data, thus causing address
88H to be skipped. In such a case, the coverage results do not cover all evaluation items.
