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.
