1. A method for evaluating via signal coupling in an electronic design, comprising the steps of:
- formulating one or more via signal coupling rules;
processing the electronic design to determine whether the via signal coupling between via pairs of the electronic design violate the via signal coupling rules; and
generating an indicator associated with the electronic design to identify violated via signal coupling rules.

Abstract
A method is provided for evaluating via signal coupling in an electronic design (e.g., a package design). In the method, one or more via signal coupling rules are formulated. One or more via pairs designed to carry differential signals are then processed to determine whether the inter-via spacing between the via pairs violates the via signal coupling rules. An indicator (e.g., a DRC and/or a report) is generated to identify violated via signal coupling rules. Processing of the electronic design may be scoped according one or a group of signal nets, or one or a group of levels of the package design.
