Quartus is capable of doing single clock design timing analysis and multi-clock design timing analysis Single … WebThese delays are reported for each clock or port for which they are relevant. If there is a case where there are multiple paths for a clock (for example if there are multiplexed clocks), then the maximum delay is reported for the tsu, th, tco, tzx, txz and tpd, and the minimum delay is reported for mintco, mintzx, mintxz and mintpd.

WebDec 20, 2010 · In fact, this is much easier since I can calculate max/min from tSU/tH of device as we did in the classic timing analyser for years . The controversy is this: how on earth can delay be tCO in this example but . tSU (for max) or -tH (for min) in the equations. Surely that is impossible to comprehend.

Re: setup and hold. this is because this are not tpd delay values. for tco you will have maximum tpd time which is important. however thold is imposed on the logic driving the part. i.e it has to have min. thold. time, the max is infinity. for setup it is also imposed on driving device, since it now have to support certein tmax tpd to ...
