DRC question on overlap
Is it possible to specificy an additional constraint in the overlap check between layers? I'd like to verifiy if there is not only an overlap, but also that one layer in fact is ABOVE the other and vice versa.
Comments
By ABOVE you mean at larger y values?
In general, DRC functions are made to be isotropic primarily. So there is no specific way of saying "above" in a sense of "coming from north".
One operation with built-in anisotropy is "moved". So you can try and AND selecting the overlap regions, use "move" to shift it a little to the north and see if that shifted shape overlaps with the NOT of the two layers.
