How tool will do the timing analysis if we dont mention the input/out delays ?

Jump to solution

HI Friends, 

In my design i dont have any input/output delay constraints. How tool will do the timing analysis in this case ?

If i put delay as 0, will it cause any functional issue ?

Any help or suggestion is highly appreciated.

If you don't create any input/out delays in the design, tool will not analyze the input/output paths.

(If you report_timing on the path, the requirement should be infinite)

We suggest you set the input/output with the board information. If you set an value(Ex: 0) for the paths, it may cause the timing violation and more run time will be used.
