High density layouts and decreasing clock cycle times have amplified the effects of interconnect time delays and electromagnetic coupling, exasperating the possibilities for signal delays and distortion. Simulation software requires realistic stable and passive models of the interconnects in combination with models of other parts of the circuits. In this paper we present a tool for studying the stability and passivity of partial element equivalent circuits (PEEC) models with time delays. This extension, however, is not specific to this particular model or application. It can be used to study other types of problems which can be described by systems of time invariant linear ordinary delay-differential equations.
