To avoid overlap of metals in different layers

surajece01

Hi,

Can any body tell me if there is any option to route a net without overlapping with metals in different layers.

Thanks

  • I have observed that in my design iam getting more coupling capacitance in case of when different metal routing overlaps than the routing in same metal layers placed closely. I tried to do fix these problem by manually clearing the overlap. it is a tedious task. I was wondering if there is any smart way of doing this.

    P.S. It is one of the signoff checks that coupling cap should not exceed a particular threshold value..
