Honored ContributorHi Rysc,
Reseting everything is safe luxury that can't be afforded in today's large designs. You need to remove reset from where it is not needed for sure. Reseting say dsp data path is completely meaningless in a system that "washes off" initial zeros and other filtering responses till they settle. It is the control logic that must have reset, state machines, enables ...etc. Surely these need not be tampered with. Hi Kalyansirinvasim, No I don't mean that, you should do that for the asynchronous anyway. I meant you can apply reset after clk edge instead of before... One other way (for exams) to get rid of all the trouble is to not register the reset at all, then there will be no paths to report and you could get a clean report (but fake), though this cheating but many designers are not aware of it.
