Implementation of MOR for time domain simulation on real-life interconnect structures

Stable equivalent circuit models cannot be guaranteed by currently available EM simulation tooling, resulting in non-convergence in time domain simulations. Theoretically it is proven that available MOR methods preserve stability and passivity in the reduction process. Implementation of MOR methods and the realization of equivalent circuit models for actual use in circuit simulation are not straightforward. This paper describes the successful implementation of a MOR method, allowing the generation of equivalent circuit models suitable for time domain simulation. Two examples of time domain simulations performed on real-life interconnect structures are given.
