CIRSIM is a software package for designing, simulating and analysing analogue electronic circuits. It will calculate the steady state performance of networks with up to 100 nodes and containing any combination of active and passive components, including transformers and thermionic valves. The amplitude / frequency response may be determined and the squarewave and pulse response of a circuit may also be calculated. CIRSIM can be used to calculate the performance of any linear network such as audio, video, i.f. and r.f. amplifiers, matching networks, oscillators, active and passive filters. The program is easy to use and many circuit examples are included together with full documentation. Both DOS and Windows versions are available.
