Capilano Computing's DesignWorks Professional is an electronic design automation (EDA) tool (also known as a schematic capture program). It allows you to create complex logic diagrams/circuits using various components (e.g. logic gates, decoders, multiplexers, full-adders). DesignWorks Professional also provides a simulator, allowing you to test your circuits as you build them.
The tools allows the calculation of application-related parameters and provides access to the digitized material data of all available EPCOS ferrites including their graphical representation. The database covers all materials described in the current data book, edition 2007. New materials for broadband transformers N45, T36 and T66 are included as well as new materials for power transformers N51 and N95. Some of the features of the current version:
IBIS Development Studio (IBISDS) is capable of viewing, editing and verifying IBIS models. You can view and edit the IBIS model in a graphical or in a text mode, just what you need for your task. The model verification is done using the golden parser (IBIS version 5.0) and can be called directly from the IBISDS user interface.
LTSpice is a free version of spice distributed by Linear Technology. Works well with wine, and its maintainer at LT is responsive to compatibility problems with wine. Doesn't have node limits and runs most macromodels for IC's available from vendors. Comes loaded with a large list of Linear Technology device models. It includes a "switcher CAD" that allows you to design and simulate a switcher power supply (with LT parts, of course) from a set of specs.
MicroCase is a powerful statistical analysis and data management program designed especially for social scientists. It includes a complete range of research tools for creating data files, cleaning and modifying data, analyzing data, and presenting results to a live audience.
PCB design tool, including schematic capture. It is apparently limited to using Advanced Circuits as the manufacturer for one's first order of circuit boards, but then it is claimed that the software will be "unlocked" and generate Gerber files which are accepted by most circuit board manufacturers.
Protel 99 SE includes an easy-to-use schematic capture editor with a huge range of components, a powerful PCB design editor with sophisticated interactive routing and placement features that are second-to-none, and an easy-to-use shape based autorouter that routes like a professional board designer.
PSpice is the de facto standard for analog and mixed-signal simulation. Engineers rely on PSpice for accurate and robust analysis of their designs. Universities use PSpice as part of their electrical engineering curricula. Semiconductor vendors around the world provide PSpice models for their devices. Numerous books have been published on PSpice that span 10 languages! PSpice includes a powerful and robust simulation engine and works with Orcad Capture, Concept HDL, or PSpice schematics in an integrated environment where engineers create designs, set up and run simulations, and analyze simulation results.
Simplorer™ is multi-domain, system simulation software for the design of high-performance electromechanical systems commonly found in the automotive, aerospace/defense, and industrial automation industries.
SimWindows is a 1D semiconductor device simulator based on rate equations for various physical processes and the detailed balance principle. The propagation and reflection of light in the structure is treated as well, so that optoelectronic devices can be simulated. The development at University of Colorado seems to have ceased at the beginning of 1999 with version 1.5.0. This is not a professionnal quality software, but you can get started in no time, so that it is good for teaching the physics of semiconductor device.
