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