CAD programs today are a dime a dozen -- but some are a lot better than others. Listed below are a few that we particularly like, both for general purpose schematic capture, simulation, and PCB layout and for specialized RF applications. Also included are some other general purpose resources on this subject area.

Specialized RF CAD/CAE Packages

Guided Wave Technology An online waveguide filter analysis and design tool developed for microwave professionals and amateurs.
MagneForce Software Systems Aproduces simulation software for the rotating electric machine industry. We simulate both the machine and its corresponding drive/load circuitry together, in this way we are able to capture the full effects of magnetic, spatial and time based harmonics. Our software is based upon finite element analysis for magnetic field calculation and various time based circuit solution techniques for the circuit simulation portion of the analysis. Our software is specifically tailored to rotating electric machinery and is very powerful but also quite user friendly. We calculate as standard output many parameters of interest to machine designers.
