S-parameters in the S-parameter matrix that satisfy passivity are checked, and an interpolation algorithm to supplement S-parameters with passivity when some S-parameters not satisfy passivity is performed. Numbers of pole-residue, times for recursion and a tolerant system error of a rational function are generated for determining S-parameters. A rational function matrix composed of S-parameters is generated by performing a vector fitting algorithm, and an equivalent circuit is generated compatible with HSPICE format based on the generated rational function matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Equivalent circuit simulation system and method for HSPICE","description":"A simulation system and method for generating equivalent circuits compatible with HSPICE reads data corresponding to N-port network system format in a storage device, and obtains S-parameter matrixes ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8489379","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
