EspoTek’s Labrador is a tiny yet powerful device that transforms a PC into a fully featured electronics lab, complete with an oscilloscope, signal generator, logic analyzer, multimeter and power supply. Qucs (Quite Universal Circuit Simulator) is an integrated circuit (IC) simulator which allow to setup a circuit with a schematic entry graphical user interface (GUI) and simulate the large and small-signal (DC, AC, S-parameter, Harmonic Balance and noise analysis) of the microelectronic circuit. Both hardware and software are 100% open-source (FOSS). Both tools will be used to illustrate complete flow of the measurements, characterization and SPICE modeling of the semiconductor devices for EDA IC design applications. EspoTek’s Labrador and Qucs cointegrations thru embedded Octave scripts will be discussed as well.

A discussion about the current state of the FOSS offerings for analogue circuit simulation, and possible paths moving forward.

The talk will provide an overview of the features, tools along along with a few examples. I will present the latest developments and plans for the future.

This talk presents Qucs (Quite Universal Circuit Simulator) features, the current status of development and the project roadmap.

Qucs is an integrated circuit simulator. The graphical user interface (GUI) is used for schematic capture and visualization of simulation results. It can simulate the large-signal, small-signal and noise behavior of the circuit. The software aims to support all kinds of circuit simulation types such as DC, AC, transient, S-parameter, noise analysis, harmonic balance analysis. Digital simulation and circuit optimization are integrated into the GUI and powered by other open-source tools (Icarus-Verilog, freeHDL, ASCO). Besides the library of components it also includes tools for the design of active and passive filters, transmission lines, attenuators and matching circuits. Interfaces for Matlab/Octave and Python are also available.

The talk will provide an overview of the features and available tools along with a selection of examples. It will present the latest developments including: ongoing migration towards the latest Qt framework; new features related to the “turn-key” Verilog-A (ADMS) model compiler as well as support for other simulation engines (Ngspice, Xyce).

A panel discussion covering subjects related to analog circuit simulation tools. Future Verilog-A efforts will be covered. Panel members include all speakers from the analog simulation session immediately preceding the panel discussion.
