Abstract All of the existing semiconductor device models in SPICES are based on a set of analytical equations which describe the currents and charges resulting from the applied bias. These have familiar names such as Gummel-Poori and BSIM. Because modern devices exhibit more complex behaviour it is very difficult to represent their operation by such a set of analytical equations. One possibility to overcome this difficulty is the use of models based on look-up tables (the so called table model approach). This paper will discuss the implementation of table models into a circuit simulator such as SPICES and examine the merits of this approach with respect to the more familiar compact models. In particular, we discuss how to construct the table models so t
