Following approaches for adding user-defined models are supported: Behavioral voltage and current sources (B devices) XSPICE code models written in C; Verilog-A models that can be compiled with OpenVAF compiler; SPICE OPUS supports parameterized netlists, parameterized subcircuits, and topology changes without simulator restart (netclass).
SPICE [5] is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community. Xspice [6] is an extension to Spice3 that provides additional C language code models to support analog behavioral modeling and co-simulation of digital components through a fast event-driven algorithm.
New models are submitted to the Coalition, where their technical merits are discussed, and then potential standard models are voted on. [4] Some of the models supported by the Compact Modeling Coalition include: BSIM3, [5] a MOSFET model from UC Berkeley (see BSIM). BSIM4, [6] a more modern MOSFET model, also from UC Berkeley. PSP, [7] [8 ...

BSIM (Berkeley Short-channel IGFET Model) [1] refers to a family of MOSFET transistor models for integrated circuit design. It also refers to the BSIM group located in the Department of Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley, that develops these models.
