Decoupling Analog Conservative Connections Using Waveform Relaxation Method

This paper presents a method for decoupling analog conservative connections suitable for implementation in SPICE simulators for simulation of large electronic systems. The Waveform relaxation method relies on insertion of interfaces between sub-circuits of the system, mimicking the behavior of transmission lines in a way that they do not change the overall response of the system. This results in a possibility to split large systems into smaller sub-systems and to calculate the response of each of them in isolation and through several iterations, thus reducing the total simulation time.
