"WebJan 15, 2016 · 01-15-2016 10:31 AM. If your clock domains are completely asynchronous then you could use a set_clock_groups command to completely cut timing between the domains. The downside is that it might cut paths that you didnt realise were being made in your design. Or you can manually false path the clock crossing paths. " - Fpga false path

Webset_false_path is commonly used for this kind of structure, even in ASICs, where the effort vs. risk tradeoff for low-probability failures is more cautious than for FPGAs. Option 2: relax the constraint with set_multicycle_path. You can allow additional time for certain paths with set_multicycle_path. It is more common to use multicycle paths ... Webset_clock_groups is preferred because it is much faster for the timing engine to process these.
