Asymptote

2D & 3D TeX-Aware Vector Graphics Language

Description
Asymptote is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. Asymptote provides for figures the same high-quality typesetting that LaTeX does for scientific text.

Features of Asymptote:

provides a portable standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations;

generates high-quality PostScript, PDF, SVG, or 3D PRC vector graphics;

embeds 3D vector PRC graphics within PDF files;

inspired by MetaPost, with a much cleaner, powerful C++-like programming syntax and IEEE floating-point numerics;

runs on all major platforms (UNIX, MacOS, Microsoft Windows);

mathematically oriented (e.g. rotation of vectors by complex multiplication);

LaTeX typesetting of labels (for document consistency);

uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;

fully generalizes MetaPost path construction algorithms to three dimensions;

compiles commands into virtual machine code for speed without sacrificing portability;

high-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications.

QUCS : A circuit simulator with graphical user interface (GUI)

Qucs stands for Quite Universal Circuit Simulator. So far Qucs is not yet finished, but it is already packed with features. Take a look at the screenshots to get a feel for what it can do. Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. After that simulation has finished you can view the simulation results on a presentation page or window. Qucs, briefly for Quite Universal Circuit Simulator, is a circuit simulator with graphical user interface (GUI). The GUI is based on Qt® by Digia®. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Harmonic Balance analysis, noise analysis, etc.
Qucsator, the simulation backend, is a command line circuit simulator. It takes a network list in a certain format as input and outputs a Qucs dataset. It has been programmed for usage in the Qucs project but may also be used by other applications.
The Qucs GUI is well advanced and allows setting up schematics and presenting simulation results in various types of diagrams. DC, AC, S-parameter, noise and transient analysis is possible, mathematical equations and use of a subcircuit hierarchy (with parameterised subcircuits) are available. Qucs can also import existing SPICE models for use in your simulations.

While Qucs is well developed, we still strive to improve the project, and will always welcome offers of help. Qucs doesn't just need help with programming, it also needs graphics, high quality example schematics, tutorials for the website and lots more.

Qucs comes with a huge array of components and models including HICUM, BSIM2, BSIM3, and soon BSIM6. It also provides many semiconductor based components and models such as OpAmps, Diodes, MOSFETs, PMOSFETs and many more. Some example schematics can be found here which demonstrate some of the abilities of Qucs, and many more examples are provided with the program.
Operating Systems

Qucs is currently developed under the GNU/Linux OS using the standard autotools with no special effort to support other operating systems. However Qucs is said to be successfully compiled and run on Windows, Solaris, NetBSD, FreeBSD, MacOS, and Cygwin... help is needed !
