Hi,


I think you're suppose to add set_max_skew to the registers R1 & R2 like in this picture:


So then the command should be like so:

set_max_skew -from R1 -to R2 1.0

Hi Nurina

Thank you, Nurina, very much.

I can't see the picture. And sorry that I didn't quite catch your point.

Where are the R1 and R2 in my design?

I can't find any register (R1, R2) on the path from PAD1 to clock_a (Path1) and the path from PAD2 to data_a (Path2).

Thank you very much.
