        I know this has been discussed before but I want to make sure I
am doing this correctly.

         

        I have a large number of differential pairs with different
spacing within the diff pairs. But I also need different spacing between
the sets of diff pairs.

         

        For example

         

        Diffa+ and Diffa- has 7 mil spacing 

        Diffb+ and Diffb- has 6 mil spacing

        Diffc+ and Diffc- has 8 mil spacing

         

        Diffa(+/-) must have 20 mil spacing to Diffb(+/-) and 

        It must have 26 mil spacing to Diffc(+/-) (for example)

         

        So in the CM, I can put the 7,6,8 mil spacing for the diff
pairs.

        But do I still use the net_spacing_type for the 20 and 26 mil
spacing?

         

        Thanks, Diane
