SUMMARY:Mixed Structural Choice Operator: Enhancing Technology Mapping wit
 h Heterogeneous Representations
DESCRIPTION:Zhang Hu (Ningbo University); Hongyang Pan (Fudan University);
  and Yinshui Xia, Lunyao Wang, and Zhufei Chu (Ningbo University)\n\nThe i
 ndependence of logic optimization and technology mapping poses a significa
 nt challenge in achieving high-quality synthesis results. This paper propo
 ses 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 int
 egrates different logic representations and stores candidates for various 
 optimization strategies. It enhances technology mapping and addresses stru
 ctural bias issues. \nThe MCH-based LUT mapping algorithm set new records 
 in the EPFL Best Results Challenge. Additionally, MCH-based ASIC technolog
 y mapping outperforms single representation mapping. MCH-based logic optim
 ization overcomes local optima and improves results.\n\nTopics: EDA\n\nTra
