MEDUSA--A Simulator for Modular Circuits

A modular circuit is defined as a combination of a certain number of k-modules, which are embedded in a carrier network. The modules may represent subcircuits of varying complexity down to single devices. Such modular circuits lend themselves to a description by a system of modular equations. MEDUSA is a user-oriented simulator which utilizes system modularity during the simulation process itself, i.e., for solving the underlying equations. This approach enables the consistent numerical solution of both the basic equations of several bipolar devices and the network equations for a circuit environment. Hence, MEDUSA in its present state is a merged device-circuit simulator meeting simultaneously the requirements of device and circuit design.
