about

fREEDA^TM is a multi-physics simulator under development by a user community from universities, research communities and laboratories. It uses state variables, local reference group concepts and automatic differentiation to capture multi-physics. As a result of this, model development is considerably simplified.

This simulation approach represents a new approach since SPICE-like analyses were developed. The approach allows the modeling of virtually any physical model and the generic model evaluation mechanism in which the primitive model equations are wrapped in generic analysis specific functions, reduces the time required for computation and development.

fREEDA^TM implements several types of analyses. It implements a DC, Harmonic Balance, several Time marching transient and a unique wavelet analysis. It also implements several device models including common three and four terminal transistors, transmission line, Foster's canonical form and diodes - electronic, optical and tunnel types.
