WebOne is the original async reset signal, and PLL_LOCK also acts as asynchronous reset signal in this case. So, all the constraints discussed here ill be valid for PLL_LOCK as well. 2. max_delay will constrain the signal to be arriving within a specific time, which is a sub-set of it being unconstrained (false path). Web23 Nov 2024 · A false path in VLSI is a timing path that may be caught even after a very long period and still provide the desired outcome. As a result, a bogus path does not need to be timed and may be ignored during timing analysis. To sum up, false paths are timing arcs in design where changes in source registers are not expected to be recorded by the ...

For example: set_false_path -from * -to [get_ports { output_port }] (where output_port is a module's top level port assigned to a pin) If Time Quest gives you a diagnostics that not every output port has a delay, you may want to add some dummy delay as well, like this: set_output_delay -clock [get ...
