ELECTROTHERMAL SIMULATION - A REALIZATION BY SIMULTANEOUS-ITERATION

After a comparison of major strategies of electro-thermal simulation ( the relaxation method and the method of simultaneous iteration) a deta iled description of the fundamentals and realization issues of the sim ultaneous iteration method is given. The paper introduces the SISSSI e lectro-thermal simulation package which is a recent realization of the latter method, fully integrated into the Cadence Opus design framewor k. The use of the package as an analogue circuit layout design verific ation tool is demonstrated through a detailed case study. (C) 1997 Els evier Science Ltd.
