On Robustness and Generalization of ML-Based Congestion Predictors to Valid and Imperceptible Perturbations

no code implementations29 Feb 2024 Chester Holtz, Yucheng Wang, Chung-Kuan Cheng, Bill Lin

Namely, we show that when a small number of cells (e. g. 1%-5% of cells) have their positions shifted such that a measure of global congestion is guaranteed to remain unaffected (e. g. 1% of the design adversarially shifted by 0. 001% of the layout space results in a predicted decrease in congestion of up to 90%, while no change in congestion is implied by the perturbation).
