Hi Sandeep,

I think we don't have any DWT variable in the Hercules devices.

Usually, customers use either PMU or RTI to measure the execution time for a function.

Please refer below example in my latest thread:

(+) RM48L952: RM48L952 PMU seems to be counting twice as many (2x) cycles as expected using EVENT == cycle count - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

Thanks & regards,
