MATLAB: How to merge code coverage results in Simulink Verification and Validation 2.5 (R2009a)

Simulink CheckSimulink Coverage

I want to be able to combine code coverage results from multiple simulations where part of the model changes between runs. The specific scenario I have is that I have multiple plant models which produce the stimulus to the model under test and I want to be able to combine the coverage results from simulations with these different plant models.

Also, it would be helpful if I could exclude certain subsystems from the coverage metrics, specifically I’d like to be able to exclude the plant models listed above.

This enhancement has been incorporated in Release 2011a (R2011a). For previous product releases, read below for any possible workarounds:

The ability to merge code coverage results is not available in Simulink Verification and Validation 2.5 (R2009a).

For model coverage it might be possible to do something similar by using a custom report (via CVHTML):

MATLAB: How to turn on the Model Coverage Report for a subsystem only in Simulink Verification and Validation 1.0.2 (R14SP2)

The ability to generate model coverage report for a specific subsystem is available in the Model Coverage Tool within Simulink Verification and Validation 1.0.2 (R14SP2) by specifying the coverage instrumentation path.

This option can be set by performing the following steps:

1. Bring up the Coverage Reporting dialog window by selecting “Tools-> Coverage Settings” menu item in a Simulink window.

2. In the dialog window, go to the Coverage tab, press the “Browse” button to specify your coverage instrumentation path.

This is also discussed in the Simulink Verification and Validation documentation which can be found by typing the following in the MATLAB command line:

MATLAB: How are the coverage metrics for the Delta column computed in a Cumulative coverage report in Simulink Verification and Validation 2.5 (R2009a)

This change has been incorporated into the documentation in Release 2010a (R2010a). For previous releases, read below for any additional information:

The delta column in a cumulative coverage report is arrived as follows:

delta_d = (d_n+1>0 & d_n ==0).*d_n+1

where

d_n+1 is the coverage data at the end of the current (n+1)th iteration

d_n is the coverage data at the end of the nth iteration

That is the delta column will show non-zero change only when d_n is zero.
