fREEDA is a multi-physics simulator that uses compact models. It can be used as an alternative Spice circuit simulator and will read a Spice netlist as well as its own (better) native netlist with many more elemenbts supported. fREEDA uses uses state variables and many new circuit concepts supporting multi physics modeling. It minimizes energy rather than minimizing current errors and so is much more robust than Spice and with high dynamic range. Many phenomena that Spice can never model can be modeled in fREEDA. Features include easy model development, high dynamic range, and support for transient, harmonic balance and multi resolution analysis. fREEDA’s large signal noise analysis captures phase noise and the effects of high levbels of noise. fREEDA also supports the integration of EM models in transient analysis. There are at least 107 different models including the major transistor models, nonlinear electro-thermal models capturing long-tail thermal effects. fREEDA 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. fREEDA(TM) can be downloaded at http://www.freeda.org
