The QUCS structure

nUCS is actually a collection of different modules, each with a different function: The GUI is used to create schematics, set up simulations, display simulation results, for writing seDL code, etc. The analogue simulator is a command line program, which is run by the GUI in order to simulate the schematic you previously set up. It takes a netlist, checks it for errors, performs the required simulation actions, and fiQDOOy SUoGuFHV D GDWDVHW.

The transmission line calculator can be used to design and analyse different types of transmission lines (like microstrips and coaxial cables). The component library manager holds models for real-life devices (like transistors, diodes, bridges and opamps). It can be extended by the user. The attenuator synthesis application can be used to design various types of passive attenuators. The command line conversion program tool is used by the GUI to import and export datasets, netlists and schematics IUoP DQG Wo oWhHU CAD/(DA VoIWwDUH.

The nUCS component library has almost all the components needed for most of the circuits, but as it is still in the development stages, some components might be missing. The following categories of components are provided: LuPSHG FoPSoQHQWV (R, L, C, DPSOLfiHU, ShDVH VhLIWHU, etc) Sources Probes Transmission lines kon-linear components (diodes, transistors, etc) Digital components cile containers (S-parameter datasets and SPICb netlists) Paintings There is also a component library that includes various
