CCSv4 - Function and line coverage tool

Hi Girish

Girish Srinivasa said:

1. I have a CCSv4 project built in debug mode and no optimizations. When I execute the function / line coverage tool, it produces a profile report. Is there a documentation to undertsand the fields in the report, say Inst exec count,  CPU instruction condition false etc..

There is a wiki topic that describes the simulator events: http://processors.wiki.ti.com/index.php/Simulator_Analysis_Event_Description

2. For certain functions I observe that  though all the lines are executed (when I step through the code), the tool shows that only the start & the last line is executed and all the other lines are not executed. What could be the reason for this? How can I understand as to why the tool produced this result?

Please provide the full CCS version number, the exact simulator being used, and a small test case.

Thanks

The wiki topic provides information on the simulator events corresponding to the cycle profiler. But the information corresponding to the line/function coverage information fields

say Inst exec count,  CPU instruction condition false is missing. Please point me to the explanation of these fields?

Lee,

                The following below is the sample code

struct buffers{

  int ptr[4];

  int inputId;

  int isRefAvailable  ;

  int frameType;  

  int gopCycle;

};

struct BufferHandle{

  int readBufIdx; 

  int writeBufIdx ;

  int validCount  ;

  int size;

  struct buffers bufs[10];

};

void main(){

  int i ;

  struct BufferHandle handle;

  handle.readBufIdx  = 0 ;

  handle.writeBufIdx = 0 ;

  handle.validCount  = 0 ;

  handle.size = 5;

  for (i = 0 ; i < (handle.size) ; i++)

  {

    handle.bufs[i].ptr[0]  = NULL ; 

    handle.bufs[i].ptr[1]  = NULL ;

    handle.bufs[i].ptr[2]  = NULL ;

    handle.bufs[i].inputId = 0    ;

    handle.bufs[i].isRefAvailable = 1 ;

    handle.bufs[i].frameType = 0    ;  

    handle.bufs[i].gopCycle  = 0    ;

}

 }

The following is the snap shot of the reported problem.

RED indicates - line not executed

GREEN indicates that the line is executed.
