Timing question

what is False path .what is it's importance .how the design is affected and how analysis made for false path in design?

Timing question

If there are two or more asynchronous blocks say A & B in ur design, with their own respective clocks clockA & clockB, then both clocks have their own critical paths and in no-way effect each other. so, while lookin for clockA, timing constraints for clockB, should be ignored and vice-versa. In Synopsys DC, set_false_path is used for constraing asynchronous and logical false paths. Others , plz correct me if i missed something.

Re: Timing question

false paths is those paths that timing is unrelated.
