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 ... WebYou can specify either a point-to-point or clock-to-clock path as a false path. A false path's -from and -to targets can be either nodes or clocks. However, the -thru targets can only be combinational nodes. For example, you can specify a false path for a static configuration …

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. WebDec 14, 2012 · It depends strongly on your design if it is necessary or not. Some timing violations can be ignored, e.g. the hardware sets an register-bit but it doesnt matter if this bit is really set in the next cycle or some cycle later. In that case you're allowed either to set a false path or a multicycle path. Dec 14, 2012. http://dchen.web.engr.illinois.edu/research/multi-clock-ICCAD07.pdf birthright israel los angeles
