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.
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.
