The structural reconstruction method in the scan chains, in the first place, establishes a first preference sequence for a certain number of scanning elements in each of these scan chains as well as a secondary preference sequence for these scan chains in each of these scanning elements respectively. Then, two-way selection is executed between the scan chains and scanning elements based on the corresponding first preference sequence and secondary preference sequence, so that these scanning elements can be redistributed to these scan chains. The structural reconstruction method and device in the invention conduct an integrated optimization for a global scan chain, where the global wiring length is shortened dramatically and the wiring efficiency is improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for reconstructing scan chain based on bidirectional preference selection in physical design","description":"Reconstruction methods and devices are disclosed for scan chains in physical design that is based on two-way priority selection.
