Abstract: To facilitate crosstalk analysis for an IC design, a plurality of input vectors are input into a gate-level simulation. In response, the gate-level simulation determines timing windows for all nets within the IC design, may perform aggressor pruning, and may then determine and output aggressor/victim pairs and associated features for the IC design. This gate-level simulation may be accelerated utilizing one or more graphics processor units (GPUs). Additionally, the aggressor/victim pairs and associated features for the IC design are then input into a trained machine learning environment, which outputs predicted delta delays for each of the aggressor/victim pairs. In this way, crosstalk analysis may be performed more accurately and efficiently.
