Hi,
I have a design rule check that involves a via layer, and the two connecting metal layers.
I want to do the same check on all vias in the stack.
Is there a way that I can create a function or loop, to avoid repeating the same lines many times.
Something in the lines of
via_stack = [2, 4, 6, 8]
def via_check(metal_below, via_layer, metal_above):
Overlap = metal_below & via_layer & metal_above
Overlap.output(100, "via rule triggered")
for layers in via_stack:
#Do design rule check
via_check(input(layers-1), input(layers), input(layers+1))
Comments
Yes, that's exactly the idea.
But DRC is Ruby, so the notation is this:
I'm just not sure what happens if you output multiple times to the same layer (here: 100).
