Integration with VectorCAST® - Code Coverage

If the chip under test has an off-chip trace interface that provides instruction trace visibility, TRACE32 records this information and takes it as base for its code coverage. The advantage of an off-chip trace interface is real-time code coverage without instrumentation of the target application. The recording volume for a test run is several TBytes of trace information if TRACE32 Trace Streaming is used or 4 GByte otherwise.



The TRACE32 code coverage results can be exported to a file and then be imported into the VectorCAST tool chain for further analysis.

The VectorCAST Harness test agent collects the coverage data, if the chip under test does not provide an off-chip trace interface. The Harness is using a Coverage RAM allocated on the target for this purpose. The size of the Coverage RAM determines the recording volume for a test run. After each test run the contents of the Coverage RAM can be saved to a file by TRACE32 and then loaded into the VectorCAST tool chain for further analysis.
