Web9 aug. 2024 · A multi-cycle path is one in which data launched from one flop is allowed (through architecture definition) to take more than one clock cycle to reach the … 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 …
WebSimply adding a multicycle path may not be correct - you have to make sure the timing of these paths work at both min and max delays, and that the data will come back on the same clock regardless of which process corner you are at. Right now, your picture shows clk1 and clk2 ans being phase aligned - they won't be. Web16 dec. 2024 · I need to constraint multicycle paths in my design.
