The rapid development of new semiconductor materials and devices has highlighted the need for compact modeling and circuit simulation tools that can be easily adapted to accommodate emerging technologies. In most instances device modeling tools employ non-linear behavioural sources and Verilog-A modules for model prototype construction. This paper is concerned with the properties and application of modular user-defined/ plugin library toolkit that combines the best features of behavioural source and Verilog-A modeling practice while encouraging user extensions. The toolkit has been implemented as a Qucs/Qucs-S/Xyce modular library that is loadable on demand. To demonstrate its capabilities and flexibility a series of compact device models are introduced and their simulated performance presented and evaluated
