Hi,


Do you reset the NCO IP after the input clock of NCO is stable? When the problem happens, if you issue a reset, does it remain the same?

Hi SK

Do you reset the NCO IP after the input clock of NCO is stable? When the problem happens, if you issue a reset, does it remain the same?

>>once clock is stable and module reset is de asserted, i am not resetting the NCO again.

but in simulation i observed that when i force reset in between the behavior is same as observed on board.

thanks & Regards
