Differential pair : Uncoupled Length Issue

harshal_pwr , 08-10-2016, 07:47 AM
Hello there;
Recently I have been fiddling with the mentioned issue a lot.

I have routed all the differential pairs according to rules specified and I have also checked other forum posts for help but none of them seem to be helping.

Can you please have a look once and guide.

I have attached screenshots of the rules, directive parameters and DRC. Hope that gives you enough idea. Let me know if you need any more info.

It's kind of obvious, but do you already have those pairs routed in the PCB? Can you post a screenshot of the layout with the pairs? Are you getting the white highlighting of the affected pairs after the DRC check?

Yep, the error you are getting is Uncoupled length - that means, that there are some places where tracks are not routed in required tolerance (e.g. the space between them is lower or bigger as specified by rules). A screenshot from PCB would help.

Yes, I am getting white highlight on affected pairs after DRC.

Here are the screenshots

Re-routed associated nets.
Errors are fixed.

Thanks, Mairomaster and Robert.
