Layout Oriented Design Practice for Capturing Distributed Effects in High-Speed Circuits.

Abstract

An integrated environment for layout-oriented design of circuits for spatial power combining system is aimed in this study. The simulation environment would include a full-wave electromagnetic simulator and a circuit simulator, TRANSIM, with a front engine, which is the major emphasis in this document. Also, the controlled and independent sources based on the Hspice models are implemented in the state-variable based object-oriented circuit simulator, TRANSIM. Transim implements local reference node instead of a global ground and this is crucial for distributed circuits. The models are implemented in object-oriented fashion and uses automatic differentiation. The same model can be used for DC, transient and harmonic balance analysis.
