Development of simulation procedures for VLSI systems (timing simulation)

A timing simulator, MEDUSA-T, based on the modular network analysis program MEDUSA was developed. The input language is compatible with ESPICE. A simplified MOS-model which is sufficiently simple for timing analysis and exact enough for circuit simulation is used. The model is derived from the ESPICE short channel MOS model. Concepts of modular analysis are realized using logic analysis for timing and circuit simulation. Investigations on modular procedures to couple circuit and timing simulation lead to a hybrid simulation program.
