Custom Rule - IPI (Inner Pad Insulation)

[dom11990]

Hi all,

How do I best define a custom rule to set a minimum clearance between vias and copper on an inner layer? The IPI is explained in the link below. I would like to make a custom rule to catch this issue because it is a real pain to fix at the end. Is hole_clearance the right one? Is there a description of what the different options are? Thanks for any help!

(rule "[Inner Via Clearance]"
	(layer inner)
	(condition "A.Type == 'Via'")
	(constraint clearance (min 1.00mm) ))
