在 Polyspace 平台用户界面中执行代码探查

计算与现有测试相关的 C/C++ 源代码覆盖率、计算执行时间

您可以在 Polyspace 平台用户界面中计算 C/C++ 代码覆盖率、执行时间或内存使用。在启用了覆盖率、执行探查或内存探查的情况下执行测试后，您可以结合测试结果来查看测试覆盖了多少代码，或查找执行时间或栈使用量方面的瓶颈。

Polyspace 选项

Calculate C/C++ Code Profiling Metrics in Polyspace Platform User Interface
Calculate code coverage, execution time, and memory use of graphically authored tests on your host computer.
Review C/C++ Code Coverage Results in Polyspace Platform User Interface
Review condition, decision, MC/DC, and other coverage metrics in Polyspace^® Platform user interface or Polyspace Access™ web interface.
Merge Coverage Results from Simulink Coverage and Polyspace Test
Gather coverage of generated code using Simulink^® Coverage™, coverage of hand written code using Polyspace Test™, and see the merged result in the Polyspace Platform user interface.

执行时间和内存使用

Review and Address Execution Time Results
After calculating the execution time of your code, review the results and address bottlenecks in execution time.
Review and Address Memory Use Results
After calculating the stack memory use of your code, review the results and address possible stack overflow.
