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.

A method for evaluating trace signal coupling of differential signals 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 for the differential signals violate the trace signal coupling rules;
- and
- generating an indicator associated with the electronic design to identify violated trace signal coupling rules.
A software product comprising instructions, stored on computer-readable media, wherein the instructions, when executed by a computer, perform steps for evaluating trace signal coupling of differential signals in an electronic design, comprising:
- instructions for determining inter-trace spacing between at least one trace pair for the differential signals;
- instructions for comparing the spacing to one or more trace signal coupling rules;
- and
- instructions for generating an indicator associated with the electronic design to identify violations of the trace signal coupling rules.
