Mixed Structural Choice Operator: Enhancing Technology Mapping with Heterogeneous Representations
DescriptionThe independence of logic optimization and technology mapping poses a significant challenge in achieving high-quality synthesis results. This paper proposes a scalable and efficient framework based on Mixed Structural Choices (MCH). This is a novel heterogeneous mapping method that combines multiple logic representations with technology-aware optimization. MCH flexibly integrates different logic representations and stores candidates for various optimization strategies. It enhances technology mapping and addresses structural bias issues.
The MCH-based LUT mapping algorithm set new records in the EPFL Best Results Challenge. Additionally, MCH-based ASIC technology mapping outperforms single representation mapping. MCH-based logic optimization overcomes local optima and improves results.
