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.

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. WebA false path in a circuit is a path which cannot be activated by any input vector. Fig. 1 shows a false path example. In practice, designers can specify don’t care conditions, such that some activated paths will become false paths under don’t care conditions. A multi-cycle path in a circuit is a path that does not have to propagate signals ...

WebFeb 25, 2024 · Thanks for helping. What is "strange" is that the design was working when it was not very crowded. More precisely, with a half-filled design, I see "2.045ns physical path delay" instead of 0.38ns ; so the timing is met. Having a more complex design "removes" logic space and Lattice doesn't seem to be able to do large physical path delays any more. 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 …
