hi,

I have a RF line of 15mil width, i need to shield this line with a ground line and the spacing between the two should be 45mil.


how to do this in orcad?
 

Hi,
if you want to shield the RFline with ground (stitching via )add via and connect to the ground.can you post snapshot i can help more..
 




thanks kapil,

I've attached a snapshot, i'm unable to get uniform spacing between the rf line & the shield over the route length.

let me knw if u need any other info.
 

Hi,
open the constraint manager--->spacing constraint -->make spacing cset and then set line to line spacing is 45mil. now it will work
 

but the spacing for differential routing is 10mil and the shield is 45..
