Model Coverage for C and C++ S-Functions

Model Coverage for C and C++ S-Functions

Model coverage is supported for C/C++ S-Functions. The coverage results for S-Function

blocks can be viewed in the same report as the rest of the model. For each S-Function

block, the report links to a detailed coverage report for the C/C++ code in the block.

To generate coverage report for S-Functions:

When creating S-Functions, enable support for coverage.

When generating coverage report, enable support for S-Functions.

Make S-Function Compatible with Model Coverage

If you use the legacy_code function, S-Function Builder block or mex function to create

your S-Functions, adapt your method appropriately to make the S-Function compatible

with model coverage.

For more information on the three approaches, see “Creating C MEX S-Functions”.

• “S-Function Using legacy_code Function” on page 18-37

• “S-Function Using S-Function Builder” on page 18-38

• “S-Function Using mex Function” on page 18-38

S-Function Using legacy_code Function

Initialize a MATLAB structure with fields that represent Legacy Code Tool

properties.

def = legacy_code('initialize')

To enable model coverage, turn on the option def.Options.supportCoverage.

def.Options.supportCoverage = true;

Use the structure def in the usual way to generate an S-function. For an example,

see “Coverage for S-Functions”.
