AIM-Spice – a new Windows version of SPICE, free student version available AKNM Circuit magic – Software to show user circuit calculation by Kirchhoff’s laws, Node Voltage and Mesh Current methods. AnaSoft Spice Analog Simulation with Schematic Capture – for Windows 95/98/NT, free beta version available Aplac – electronics circuit simulation program, free demo version available, uses Spice component models, very suitable for RF simulation atlc – Arbitrary Transmission Line Calculator (for electrical transmission lines) – atlc is a computer aided design (CAD) package for the design and analysis of electrical transmission lines and directional couplers of totally arbitrary cross section. ‘atlc’ can handle any cross section and any number of different dielectrics. It’s also possible to analyse 3 conductor lines (directional couplers). The software is free, open-source and for Unix or GNU/Linux machines. It is not really interended for Windoze machines. Bode Diagrams – Windows application for Bode’s diagrams drawing and analysis. It allows to trace and to print the Bode diagrams, both asymptotic and true, and the analysis (zeros, poles, stabilization to open and closed ring, reaction, regulation, project and verification of control systems). The departure function can be expressed in whichever format, also mixed.
