COVERAGE
The command COVERAGE shows statistics about the executed code of an application or parts of an application. Refer to Fully Qualified Symbols for details about the syntax of modules.
| Syntax | Description | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| COVERAGE | Displays coverage information of the whole application. | ||||||||||
|
COVERAGE \module [DETAILS] |
Displays coverage information for the selected module. The option DETAILS provides additional information about conditional instruction execution. | ||||||||||
| COVERAGE \module\func [DETAILS] | Displays coverage information for symbols of function func contained in module. The option DETAILS provides additional information about conditional instruction execution. | ||||||||||
| COVERAGE ASM |
Displays coverage information including assembly instructions
of the whole application. The output format has the form:
<qualifier> | <addr> <opcode> <assembly code> The values below lists the possible qualifiers:
|
||||||||||
| COVERAGE CLEAR | Clear all code coverage information. | ||||||||||
| COVERAGE FLOW filespec | Prints program execution flow information to a file specified by filespec. Available only in Simulation mode. | ||||||||||
| COVERAGE LOAD path\filename | Load the code coverage information from a file. This allows to merge code coverage information of previous sessions with the current session and therefore multi-session testing of an application. | ||||||||||
| COVERAGE SAVE path\filename | Save the code coverage information to a file. |
Example
The following example were created using the MEASURE example program of the C51 Compiler package.
\\Measure\MEASURE\{CvtB} - 32% of 52 instructions executed
\\Measure\MEASURE\{CvtB} - 0% of 127 instructions executed
\\Measure\MEASURE\{CvtB} - 100% of 1 instructions executed
\\Measure\MEASURE\{CvtB} - 100% of 6 instructions executed
\\Measure\MEASURE\{CvtB} - 0% of 595 instructions executed
\\Measure\MEASURE\{CvtB} - 0% of 5 instructions executed
\\Measure\MEASURE\{CvtB} - 100% of 1 instructions executed
\\Measure\MEASURE\SAVE_CURRENT_MEASUREMENTS - 0% of 46 instructions executed
\\Measure\MEASURE\TIMER0 - 72% of 94 instructions executed
\\Measure\MEASURE\READ_INDEX - 0% of 64 instructions executed
\\Measure\MEASURE\CLEAR_RECORDS - 100% of 24 instructions executed
\\Measure\MEASURE\MAIN - 31% of 215 instructions executed
\\Measure\MCOMMAND\{CvtB} - 0% of 74 instructions executed
\\Measure\MCOMMAND\MEASURE_DISPLAY - 100% of 44 instructions executed
\\Measure\MCOMMAND\SET_TIME - 0% of 58 instructions executed
\\Measure\MCOMMAND\SET_INTERVAL - 0% of 101 instructions executed
\\Measure\GETLINE\GETLINE - 78% of 51 instructions executed
\\Measure\TOUPPER\{CvtB} - 100% of 18 instructions executed
\\Measure\TOUPPER\{CvtB} - 51% of 91 instructions executed
\\Measure\TOUPPER\{CvtB} - 0% of 0 instructions executed
Note
- The options ASM, CLEAR, DETAILS, LOAD, and SAVE are valid for some drivers only.
- Use the command LOG to copy code coverage information to a log file.
- The Code Coverage Window also shows coverage information.
