Open-Source Software

ChipDesign uses and contributes to open-source EDA software in order to lower costs.

NF2FF

NF2FF is a planar near-field to far-field transformation for near-field antenna measurement setups (Link).

rfMaxima

rfMaxima is an RF toolbox for the wxMaxima computer-algebra system. rfMaxima allows for symbolic derivation, as well as numerical evaluation (incl. Bode and Smith-chart plotting), of 2-port network (ABCD, G, InverseABCD, H, S, Y, Z), noise and stability parameters. Derivations are based on the solution of the set of Kirchhoff current- and voltage-law equations representing the 2-port. Expressions can be exported to HTML or TeX. Figures can be exported to EPS or PNG (Link).

Verilog-A RF MEMS Models

The Verilog-AMS models can be used with SPICE solvers for DC, small-signal (AC, S-parameters (SP)) and large-signal (harmonic balance (HB), periodic steady-state (PSS), quasi-periodic steady-state (QPSS)) simulation of analog / RF circuits based on RF MEMS components (Link).
