cad (30)

Complete set of free CAD tools and portable libraries for VLSI design. It includes a VHDL compiler and simulator, logic synthesis tools, and automatic place and route tools. Advanced verification tools for functional abstraction and static timing analysis are part of the system. A complete set of portable CMOS libraries is provided, including a RAM generator, a ROM generator, and a data-path compiler.

Converts .PcbDoc and .SchDoc files created with Altium to KiCad formats

Archimedes Heckert gnu.small.png
Archimedes is a free package for semiconductor device simulations. It is intended to assist engineers in designing and simulating submicron and mesoscopic semiconductor devices based on the Ensemble Monte Carlo method. It is able to handle a wide variety of materials and structures, which are described through simple scripts.

It is a 2D Monte Carlo simulator which can take into account all the relevant quantum effects by means of Bohm effective potential. The description of the device is very general and made by means of a simple script language, which makes GNU Archimedes a powerful tool for the simulation of quite general 2D semiconductor devices. Some very interesting results have been obtained and they will be put, as soon as possible, on the web page (some results are already available in the documentation).

'atlc' (Arbitrary Transmission Line Calculator) is a computer aided design (CAD) package for designing and analysing electrical transmission lines and directional couplers of totally arbitrary cross section, with an arbitrary number of different dielectrics.

The analysis programs in 'atlc' lets users find the electrical properties of a transmission line or coupler whose physical dimensions are known. The design programs lets users physically realise a transmission line or coupler with certain given electrical properties.

The package supports multiple CPUs, as some parts are CPU intensive. It is most likely to be useful to radio amateurs.

BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.

'Darwin2k' is a robotics design and simulation program. Its simulation capabilities support engineering design and controller prototyping for robotic application; for example, it includes detailed motor and gearhead performance models, and the ability to estimate stresses in structural elements during simulation. Darwin2K is *not* an end-user application. Most uses will require at least a little coding, usually to specify application-specific robot controllers and models, high-level task descriptions, or specialized simulation components. That being said, Darwin2K does include a range of general-purpose robot models, controllers, and simulation and analysis capabilities, useful in a wide range of robot design and programming applications, that eliminate most of the work in developing a task-specific simulation or optimized robot prototype. The system also includes a distributed evolutionary algorithm for automated synthesis and optimization.

Electric Heckert gnu.small.png
Electric is a CAD program for designing electrical circuits, handling custom IC layout, schematic drawing and hardware description language specifications. Several CAD operations are supported, such as rule checking and simulation. Many different types of designs can be produced and input or output in a wide variety of formats.

GNU Electric offers a wide range of synthesis and analysis tools for working on the circuitry, including design rule checking, simulation, routing, layout vs. schematic, logical effort… It also has many importers and exporters for interfacing to other EDA (Electronic Design Automation) systems. It even has a constraint system for managing chip layout.

FreeCAD is an CAx RAD based on OpenCasCade, Qt and Python.

It features some key concepts like Macro recording, Workbenches, ability to run as a server and dynamically loadable Application extensions and it is designed to be platform independent.

The gEDA project is working on producing a full GPL'd suite of Electronic Design Automation tools. These tools are used for electrical circuit design, simulation, prototyping, and production. The gEDA project was started because of the lack of free EDA tools for UNIX. The tools are being developed mainly on GNU/Linux machines, but considerable effort is being made to make sure that gEDA runs on other UNIX variants.

'GLE' is a package of C functions that draw extruded surfaces, including surfaces of revolution, sweeps, tubes, polycones, polycylinders and helicoids. The extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways. The GLE library generates 3D triangle coordinates, lighting normal vectors and texture coordinates as output. It uses the GL or OpenGL API's to perform the actual rendering.
