Differential Pair Routing

Vishal Batham

Hello,

Is it possible to route two or more differential pair at same time??

Suggest if possible...

  • steve

    Yes, invoke Route - Connect (one method) then window the pins or connections and you will route all the diff pairs. You might want to get them to the actual spacing between diff pairs first to ease the routing first though.

    Not as such but you can use Max uncoupled length. There's an app note that goes through all the diff pair settings:- http://orcad.co.uk/images/PDF/diffpairs_definition.pdf and http://orcad.co.uk/images/PDF/diffpairs_supplemental_notes.pdf
