QucsatorRF – RF and microwave circuit simulator

QucsatorRF is a command-line circuit simulation engine designed particularly for radio-frequency and microwave circuits. It serves as a specialised simulation backend for Qucs-S, which provides a graphical interface for schematic capture, simulation control, and visualisation.

The simulator accepts a network list as input and generates results using the Qucs XML dataset format. While general-purpose circuit simulation is possible, its main strength is RF and microwave modelling, complementing SPICE-compatible engines such as Ngspice used by Qucs-S.

This is free and open source software.

Key Features

• Command-line driven circuit simulator focused on RF and microwave circuit design.
• Designed for integration with the Qucs-S graphical circuit design environment.
• Supports RF-oriented component and transmission-line models including microstrip devices.
• Provides S-parameter simulation for analysing high-frequency networks.
• Supports general circuit simulation, although RF and microwave applications are its primary focus.
• Reads circuit network lists and writes simulation results using the Qucs XML dataset format.
• Includes QucsconvRF, a companion utility for converting circuit and simulation data formats.
• QucsconvRF supports conversion of a range of SPICE-related data and device representations.
• Supports conversion of VDMOS device definitions and magnetic CORE data from SPICE formats.
• Can optionally be built with ADMS support for Verilog-A device modelling.
• Has no mandatory runtime dependencies beyond the standard C++ library.
• Uses CMake as its build system with Flex, Bison, Gperf, and Dos2unix required when compiling from source.
• Can be compiled natively on Linux and with the MSYS2 environment on Windows.
• Distributed as part of Qucs-S, so Qucs-S users normally do not need to install the simulator separately.
• Available as a separate package in some Linux distributions.
