在包含 C Caller 模块的模型上生成测试

R2026b

此示例说明如何在包含 C Caller 模块和自定义 C 代码的模型上使用测试生成

打开包含 C Caller 模块和自定义代码的模型

open_system('sldvexCCallerBlock');

生成测试以确保模型的覆盖率

使用 sldvrun 函数运行 Simulink® Design Verifier™ 分析。

opts = sldvoptions;
opts.Mode = 'TestGeneration';
opts.ModelCoverageObjectives = 'ConditionDecision';
opts.SaveHarnessModel = 'off';
opts.SaveReport = 'off';

[status, fileNames] = sldvrun('sldvexCCallerBlock', opts);

验证覆盖率

使用 sldvruntest 函数验证测试套件是否实现了完整模型覆盖率。

[~, finalCov] = sldvruntest('sldvexCCallerBlock', fileNames.DataFile, [], true);
cvhtml('Final Coverage', finalCov);

清理

要完成示例，请关闭所有模型。

close_system('sldvexCCallerBlock', 0);
