Abstract:
A multiple-layer circuit board has a signaling layer, an exterior layer, and a ground layer. A pair of differential signal lines implemented as strip lines are within the signaling layer, and propagate electromagnetic interference (EMI) along the signaling layer. An element conductively extends inwards from the exterior layer. A void of a defected ground structure within the ground layer has a size, shape, and a location in relation to the element to suppress the EMI propagated by the strip lines. A resistive material of the defected ground structure along a perimeter of the void improves suppression of the EMI propagated by the strip lines, via the resistive material absorbing the EMI.

Abstract:
A system may include an input engine and a symmetry verification engine. The input engine may access an electronic circuit design of an electronic design automation (EDA) tool as well as identify a particular net in the electronic circuit design. The a symmetry verification engine may identify a pair of differential signal vias in the electronic circuit design corresponding to the particular net and determine a verification area surrounding the pair of differential signal vias. The symmetry verification engine may also verify that a particular ground via within the verification area satisfies symmetry criteria with respect to the pair of differential signal vias.
