We give in this article an introduction to the Verilog-A SmartSpice interface. This new feature in SmartSpice allows the user to write their own physical models in the Verilog-A language.

Ramtron International Corporation has developed a ferroelectric capacitance model with a new concept of double distributions of domain reversal voltages.

Acknowledging the need for more flexibility, SmartSpice now provides three numerical methods for linear system solution. The additional solvers provide for greater capacity by minimizing memory requirements and reducing the

The BSIM4 model provides a RF CMOS modeling capability. Prior to the BSIM4 model the RF modeling was accomplished by using macro models. The macro models were complex, contained many
