List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Circuit macros is a set of macros for drawing high-quality line diagrams to include in TeX, LaTeX, web, or similar documents, with support for SVG and other formats. It uses the M4 macro processor and a Pic interpreter and can produce TikZ code.
XCircuit is a schematic capture program for drawing publication-quality VLSI electrical circuit schematic diagrams and related figures. It's part of the Open Circuit Design tools. It's primarily intended for ULSI/VLSI IC design and not for PCB design, the latter though is still possible. [2]
Dia has special objects to help draw entity-relationship models, Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.
The transmission line calculator can be used to design and analyze different types of transmission lines (e.g. microstrips, coaxial cables). A component library manager gives access to models for real life devices (e.g. transistors, diodes, bridges, opamps). These are usually implemented as macros. The library can be extended by the user.
The technique involves modeling the individual linear components as an N port admittance matrix, inserting the component Y matrix into a circuits nodal admittance matrix, installing port terminations at nodes that contain ports, eliminating ports without nodes though Kron reduction, converting the final Y matrix to an S or Z matrix as needed ...

A 2D CAD drawing A 3D CAD model Computer-aided design ( CAD ) is the use of computers (or workstations ) to aid in the creation, modification, analysis, or optimization of a design . [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to ...
