WebTperiod (min) = 200+ 200 + 400 = 800 ps. The minimum time period that it can operate at is 800 ps, or a maximum frequency of 1.25 GHz. In this post, we have discussed how PVT variations in delay can cause a timing path to be both setup and hold critical. Also, we discussed how it limits the frequency of operation. Web1) u have to fix the Hold than the setup if hold is there the chip will not work . if setup is there the chip will work with the redused frequency.so u have to fix the HOLD first. 2) the hold violation will be fixed by inserting the delay cells or the basic buffers in the …
