The scan chain engine iteratively executes partitioning on the IP block to generate a set of partitions. Each partition in the set of partitions has a number of EXTEST wrapper cells that does not exceed the maximum number of EXTEST wrapper cells per EXTEST scan chain. The scan chain engine selectively merges partitions of the set of partitions to form a set of populated partitions that each include an EXTEST wrapper cell. The number of partitions is equal to the set number of EXTEST scan chains for the IP block. The scan chain engine generates wire paths connecting EXTEST wrapper cells of each populated partition to construct the set number of EXTEST scan chains for the IP block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"IP block scan chain construction","description":"A scan chain engine can determine a set number of EXTEST scan chains for the IP block and based on a predetermined maximum number of EXTEST wrapper cells per EXTEST scan chain.
