Crosstalk constrained global route embedding

- Route Embedding, a new method for mitigating the impact of crosstalk, is presented. It modifies a set of global-route structures to prevent timing and noise-margin violations caused by crosstalk, while maintaining routing constraints. An accurate and computationally-efficient empirical model for crosstalk impact is presented which by capturing noise and delay-changes on coupled conductors, permits a performance-driven approach to addressing crosstalk. Linearized crosstalk constraints are derived and satisfied for the expected noise and wire-delays at critical signal sinks. Unsatisfied constraints are resolved by inserting ground shields and by selective re-route through uncongested regions. Routing capacity constraints are enforced to guarantee a detailed routing solution.
