Thanks for the help.
In ECSet the relative propagation delay tab there are matched groups for which the delay is set for the longest pin pair in pin pair tab for some matched groups.but i cant set it for diff pairs.
Did you mean to group all the diff pairs ( Diffpair 1,Diffpair 2,Diffpair 3...) into matched group (in ECset) and then set the delay in Relative Propagation Delay tab?
I am not able to create a match group (in ECset /nets) by selecting all the diff pairs.
What is Sourcelink.If you dont mind can u send me the link of the video.?
Thanks in advance..
