An event driven approach for mixed gate and circuit level simulation

A new algorithm for mixed gate and circuit level simulation is described. I he algorithm* is b.ised on n modular view of electronic networks in which individuri modules nuiy be described cillicr al die ciicuil or at the lo^ic level. Consistency is ensured by employing a novel logic gate model which is derived by abstraction from the underlying (and more detailed) circuit model. Computational efficiency is achieved'by exploiting temporal sparsencss both for circuit and logic level modules through the use of event driven techniques. The implementation of the algorithm in the SAMSON program is briefly described and a sample simulation example is presented.
