We extend an existing probabilistic congestion model to consider shielding for crosstalk reduction. We then develop a multilevel router to study the impact of various congestion models on routing congestion by using large industrial design examples. We show that (1) when shielding is applied as a post-routing optimization for crosstalk reduction, the existing probabilistic model, when compared to a deterministic routing-order dependent congestion model, reduces routing congestion by 17.1% on average under the given routing area constraints, or reduces routing area by 9.4% on average under the given routing congestion constraints; (2) our extended probabilistic congestion model considering shielding enables shielding reservation and minimization for routing and achieves routing congestion (or area) reduction by 47.7% (or 31.0%) on average under the given routing area (or congestion) constraints, when compared to the above deterministic congestion model not able to estimate shielding and therefore not able to minimize shielding during routing.
