µVISION DEBUGGER: Save/Restore Code Coverage Information

Information in this article applies to:

• µVision Version 2.38, or higher
• Cx51 Compiler Version 7, or higher

QUESTION

I need to validate a complex Smart Card Operating System. For software certification, I need a report showing that all paths in my program are fully executed. The nature of my system requires that I restart the debugger several times. 

Is there a way to save and restore code coverage information so that I can merge the results of several test sessions?

ANSWER

Yes. The µVision Debugger COVERAGE command has the additional options SAVE and RESTORE. These allow you to save the current code coverage status and restore this information in another debug session. For example:

• COVERAGE \\task\module\function generates coverage information for a specific module or function.
• COVERAGE DETAILS generates a detailed coverage report.
• COVERAGE ASM includes assembler instructions in the coverage report.
• COVERAGE SAVE saves current code coverage information to a file.
• COVERAGE LOAD restores code coverage information from a file.
