Set_False_Path Vs Set_Clock_Groups. If your design has clock domains that are. by default, the clock domains are all synchronous and related to each other. It's a common mistake to use set_false_path in. in order to constraint the design properly for timing analysis, should we use set_clock_groups to set clocks. the set false path (set_false_path) constraint allows you to exclude a path from timing analysis, such as test logic or any other path. For example, i can remove setup checks while keeping hold. if no timing requirements are necessary on a path, it should be declared as a false path. set_false_path allows to remove specific constraints between clocks. in essence, what it does is a set_false_path between the clocks n the first group to the clocks in the second two. in a simple design with three plls that have multiple outputs, the set_clock_groups command can cut timing between clocks. this is equivalent to setting the following two false path statements.
