Reduced-order macromodeling of parameterized frequency responses

Purpose - The purpose of this paper is to propose a methodology for forming compact reduced-order macromodels of interconnect systems to enable real-time design exploration and efficient manufacturing tolerance assessment. Design/methodology/approach - A multi-parameter moment-matching-based technique and a multivariate orthonormal macromodelling technique are combined to form an effective and efficient reduced-order model that approximates the frequency-domain behaviour of an interconnect system based on several design variables. Findings - Results will confirm the efficacy of the approach and its superiority to application of the moment-matching-based method alone. Research limitations/implications - With the ever growing complexity of high-frequency systems in the electronic industry, formation of compact macromodels is crucial for fast and efficient design and analysis. Originality/value - Combination of the individual techniques is novel and increases the efficiency of the ultimate macromodel.
