Hi,
I want to match the total length of my Diff pairs - all should be in a specified range in comparison to each other. I have defined an Electrical rule set and assigned some min/max margins. Then I assigned that ECS to my three differential nets and analyzed them. I found out that some of them are out of margin. Unfortunately, tune delay can only increase length of every single line not both!. I have some sample boards from various vendors which I see they were able to match diff pairs. I spent lots of time on it. I appreciate any help.
Thanks in advance,
Hossein
