Model selection for computer simulation of digital m.o.s.f.e.t. l.s.i. circuits

The paper describes a procedure for selecting from a collection of models, for the purpose of m.o.s.f.e.t. circuit simulation, a m.o.s.f.e.t. device model that provides the best trade-off between accuracy and computational efficiency. The selection method employs the concept of the accuracy-efficiency product, and is suited to a situation in which only a few models will be used to represent all the devices in the network. Another selection method is also proposed, which employs a `model performance function¿¿ and is appropriate for situations in which each device in a network can be represented by a different model. The results of applying these two selection methods to a particular m.o.s.f.e.t. model library are presented
