Introduction

QucsStudio is mainly a circuit simulator that has evolved out of the project Qucs, but isn't compatible with it. It's meant be be a test project to create a complete development environment for electrical engineers. (graphical user interface with circuit simulator, PCB layouting, numerical data processing etc.) The application uses the free port Q.../Free of the graphical user interface Qt® by Trolltech®.

Bug reports, comments and other help are very welcome!

Legal Stuff

QucsStudio is free software that is allowed to be used and distributed freely. There is no warranty at all, not even for merchantability or fitness for a particular purpose.

Features

Currently the following applications are supported: The following applications are planned to be implemented and tested (Does anyone want to help?):

Examples

The following files contain circuits that demonstrate the functionality of the program. They are archive files that are decompressed by the program. (menu: Project -> Extract Package... or by Drag'n'Drop into project list).

binary component library contains the following models: Curtice, Statz, TOM1...3, EKV, HICUM L0/L2, photodiode, stripline and more (many thanks to Mike Brinson for contributing most of the models)
DC analysis
AC analysis
transient analysis
s-parameter analysis
Harmonic Balance analysis
digital simulations
system simulation
