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. WebA Multi-Cycle Path (MCP) is a flop-to-flop path, where the combinational logic delay in between the flops is permissible to take more than one clock cycle. Sometimes timing …
