Top-Level Model Coverage Report
19-27
• The position of a character in the string corresponds to the input port number.
• The character at the position represents the value of the input. (T means true; F
means false).
• A boldface character corresponds to the value of the deciding input.
For example, FTF represents a condition case for a three-input block where the second
input is the deciding input.
The Decision/Condition column specifies the deciding input for an input condition case.
The True Out column specifies the deciding input value that causes the block to output
a true value for a condition case. The True Out entry uses a condition case expression,
for example, FF, to express the values of all the inputs to the block, with the value of the
deciding variable in bold.
Parentheses around the expression indicate that the specified combination of inputs did
not occur during the first (or only) test case included in this report. In other words, the
test case did not cover the corresponding condition case. The False Out column specifies
the deciding input value that causes the block to output a false value and whether the
value actually occurred during the first (or only) test case included in the report.
If you select Treat Simulink Logic blocks as short-circuited in the Coverage
Settings dialog box, MC/DC coverage analysis does not verify whether short-circuited
inputs actually occur. The MC/DC analysis table uses an x in a condition expression (for
example, TFxxx) to indicate short-circuited inputs that were not analyzed by the tool.
If you enable this feature and Logic blocks are short-circuited while collecting model
coverage, you might not be able to achieve 100% coverage for that block.
Cumulative Coverage
On the Results tab, if you select Save cumulative results in workspace variable
and on the Report tab, Cumulative runs, the results of each simulation are saved and
recorded in the report.
In a cumulative coverage report, the results located in the right-most area in all tables
reflect the running total value. The report is organized so that you can easily compare
the additional coverage from the most recent run with the coverage from all prior runs in
the session.
A cumulative coverage report contains information about:
