WebWith Enhanced Constraints Flow, use the Constraint Manager to manage all your design constraints. SDC Timing Constraints Timing constraints represent the performance goals … 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 paths with large delays are designed such that they are permitted multiple cycles to propagate …

Web– Constraints on certain timing paths for special considerations. Examples are false path constraints and multicycle path constraints. • Advanced – Special timing constraints such as clock latency and clock groups Constraints List Webexception commands. Here is an excerpt from the set_multicycle_path manpage: The set_multicycle_path command is a point-to-point timing exception command. The command can override the default single-cycle timing relationship for one or more timing paths.

Multicycle paths between different clock domains – VLSI Pro

WebFor example, if the source clock is twice as fast (half period) as the destination clock, a -start multicycle of 2 is usually required. Hold multicycles (-hold) are computed relative to setup multicycles (-setup). The value of the hold multicycle represents the number clock edges away from the default hold multicycle.

WebNo, a multicycle path is a combinatorial path which has more than one clock cycle delay. The designer makes sure that timing requirements are met (by keeping the inputs stable and sampling the output only after a certain number of clock cycles) and tells the synthesis tool he’s done so by setting a multicycle path constraint. WebA multicycle constraint adjusts this default setup or hold relationship by the number of clock cycles you specify, based on the source (-start) or destination (-end) clock. A …
