BLOCK COVERAGE




The nature of the statement and block coverage looks somewhat same. The difference is that block coverage considers branched blocks of if/else, case branches, wait, while, for etc. Analysis of block coverage reveals the dead code in RTL.

Block coverage report of the above example:




There are total 9 blocks at lines
5,7,8,11,15,17,20,21,22

Covered 6 blocks. They are at lines
5,7,8,11,17,22

Uncovered 3 blocks. They are at line
15,20,21

Coverage percentage: 66.67 (6/9)
