Get decision coverage for Subsystem 1

Execute the commands for Subsystem 1 decision coverage:

testobj1 = cvtest([model '/Subsystem 1']);

testobj1.settings.decision = 1;

covobj1 = cvsim(testobj1);

Get decision coverage for Subsystem 2

Execute the commands for Subsystem 2 decision coverage:

testobj2 = cvtest([model '/Subsystem 2']);

testobj2.settings.decision = 1;

covobj2 = cvsim(testobj2);

Add coverage results for Subsystem 1 and Subsystem 2

Execute the command to create cumulative decision coverage for Subsystem 1 and

Subsystem 2:

covobj3 = covobj1 + covobj2;

Generate coverage report for Subsystem 1

Create an HTML report for Subsystem 1 decision coverage:

cvhtml('subsystem1',covobj1)

The report indicates that decision coverage is 50% for Subsystem 1. The true condition

for enable logical value is not analyzed.

Generate coverage report for Subsystem 2

Create an HTML report for Subsystem 2 decision coverage:

cvhtml('subsystem2',covobj2)

The report indicates that decision coverage is 50% for Subsystem 2. The false condition

for enable logical value is not analyzed.
