Black-box identification of delay-based macromodels from measured terminal responses

This paper proposes a new formulation of black-box macromodels for electrically-long scalar interconnects, together with an efficient numerical identification scheme and an optimized SPICE synthesis. The proposed methodology explicitly preserves in the macromodel structure the infinite reflections due to termination mismatch, thus allowing for compact and low-complexity equivalent circuits. Numerical examples show the excellent performance of the proposed technique.
