Abstract :
This letter presents an efficient and stable macromodeling formulation for electrically long high-speed modules characterized by tabulated data. The resulting system of delay differential equations contains a reduced number of delayed rational terms for networks with dominant periodic reflections leading to faster transient simulations. A method is also presented for macromodel stability verification and enforcement.
