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. Web1. Intel® FPGA AI Suite Getting Started Guide 2.

WebNov 24, 2024 · The timer has automatically timed these paths as synchronous. In order to constrain asynchronous clock domain crossings correctly, there are four things to consider: If there are no paths between the two clocks, the simply use set_clock_groups or set_false_path between the two clocks. If the paths are all single big CDCs then you can … Webset_clock_groups is preferred because it is much faster for the timing engine to process these. False paths add quite a bit of overhead, and are overkill if you're just trying to prevent CDCs. 1. supersonic_528 • 20 days ago. There is actually a …
