Hi Debasish,
I'm not quite sure what you are looking for. If you are asking if CCS can be used to debug both the ARM and DSP at the same time, then the answer is "yes". CCS supports what is called "multi-core debug" which allows you to debug multiple cores on a device at the same time. Details are in the below article:

Thanks
