Code Coverage Tool

15 Mar 2007 (Updated 03 Jun 2009)

Code Coverage Tool measures C statement coverage in generated code.

File Information
Description	The Code Coverage Tool (CCT) measures C statement coverage in code built as a Real-Time Workshop S-Function. It operates in conjunction with lcc (the C-Compiler that ships with the standard MATLAB installation). CCT inserts instrumentation code into the assembly source generated by lcc during a normal compile. This additional code logs when a line is executed in memory on the PC. When a simulation completes, the line execution counts are sent to the MATLAB base workspace. A full description of CCT and installation instructions are included in the cct.zip download. See the file readme.html.
Required Products	Embedded Coder Simulink Stateflow Stateflow Coder Real-Time Workshop
MATLAB release	MATLAB 7.7 (R2008b)
Other requirements	Windows 32 bit machines only.

30 Mar 2007	Venkata Chittem	This tool is giving line coverage information. But code coverage will be incomplete without a mention of MC/DC (Multiple conditions and Decision coverage) information!

31 Dec 2007	Krishan Kumar	It gives the coverage of the last run, it doesn't give coverage for the cumulative run as in model coverage.

Updates
16 Mar 2007	Path bug found in cct_setup.m during testing. A file separator was missing when toolroot was expanded.
01 Apr 2007	Main reason is original submission only worked with R2006a. This version contains an installer to allow CCT to work on R2006a and R2006b. Pre-built files have been added to improve usability also.
19 May 2009	Compatibility updates with R2008b and R2009a (HTML formatting and data communication with MATLAB workspace). I have added a makefile so that the compiler interceptor executables can now be built by lcc from the supplied sources.
03 Jun 2009	cct_setup so build works when there are spaces in the path. Added the html files in for a typical build. cct_setup now forces "Generate Report" on, so there is a file to put the coverage in.
