Google propogation delay, your pipeline's length and delay of devices within that pipe determine the max frequency your circuit can run at (a very high level overview).
- kingosticks 5y agoHow is pipeline length related to max frequency?
- enchiridion 5y agoPhysical length the signal has to travel.
- amluto 5y agoIt’s related indirectly. A longer pipeline tends to result in shorter stages within the pipeline. (This is the whole point of pipelining.)
- kingosticks 5y agoOK, yes there's often correlation but that's it. A longer pipeline doesn't affect max circuit frequency. The other sibling comment regarding distance isn't true. regardless of how insane your feedbacks are. Physical placement tools have always handled this in my experience (as a chip designer for 10+ years).

- u320 5y agoThere is no point of lengthening the pipeline if you don't get higher frequency from it. It would just add complexity and and a higher branch mispredict penalty.
