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

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.
