Compact device modeling and simulation with Qucs/Qucs-S/Xyce modular libraries

Abstract—The rapid development of new semiconductor materials and devices has highlighted the need for compact modeling and circuit simulation tools that can be easily adapted to accommodate emerging technologies. In most instances device modeling tools employ non-linear behavioural sources and Verilog-A modules for model prototype construction. This paper is concerned with the properties and application of modular user defined/plugin library toolkit that combines the best features of behavioural source and Verilog-A modeling practice while encouraging user extensions. The toolkit has been implemented as a Qucs/Qucs-S/Xyce modular library that is loadable on demand. To demonstrate its capabilities and flexibility a series of compact device models are introduced and their simulated performance presented and evaluated.

FOSDEM 2017 EDA Devroom Call for Participation

FOSDEM 2017 Electronic Design Automation Devroom
Call for Participation

This is the call for participation in the FOSDEM 2017 devroom on Free/Open Source Software (FOSS) Electronic Design Automation (EDA) tools, to be held on Sunday 5 February 2017 in Brussels, Belgium. We are looking for contributions under the form of talks and tutorials covering the following main topics:

• Printed Circuit Board (PCB) design tools (e.g. KiCad and gEDA)
• Analogue and digital simulators (e.g. ngspice, Qucs, Gnucap, Xyce, GHDL, Icarus and Verilator)
• Any other EDA tools such as high-level tools for digital hardware design (e.g. Migen) and HDL synthesis tools (e.g.Yosys)
• Inter-project opportunities for collaboration

We hope to provide an opportunity for attendees to bring themselves up to date on the latest FOSS EDA developments, share knowledge and identify opportunities to collaborate on development tasks. Have a look at last year's event for a taste of what the EDA devroom is about.

The submission process
Please submit your proposals at 

https://penta.fosdem.org/submission/FOSDEM17 

before 1 December 2016.

If you already have a Pentabarf account (for example as a result of having submitted a proposal in the past), make sure you use it to log in and submit your proposal. Do not create a new account if you already have one. Please provide a bit of information about yourself under Person -> Description -> Abstract. When you submit your proposal (creating an "Event" in Pentabarf), make sure you choose the "Electronic Design Automation (EDA) devroom" in the track drop-down menu. Otherwise your proposal might go unnoticed. Fill in at least a title and abstract for the proposed talk and a suggested duration. Bear in mind that a lot of the value in these meetings comes from the discussions, so please be reasonable regarding the duration of the talk.

Important dates

• 1 December 2016: deadline for submission of proposals
• 11 December 2016: announcement of final schedule
• 5 February 2017: devroom day

Recordings
The FOSDEM organisers hope to be able to live-stream and record all the talks. The recordings will be published under the same licence as all FOSDEM content (CC-BY). Only presentations will be recorded, not informal discussions and whatever happens during the lunch break. By agreeing to present at FOSDEM, you automatically give permission to be recorded. The organisers will agree to make exceptions but only for exceptional and well-reasoned cases.
Mailing list

Feel free to subscribe to the mailing list of the EDA devroom to submit ideas, ask questions and generally discuss about the event.

Spread the word!
This is the third EDA devroom at FOSDEM. The first two were very well received. Let's make sure as many projects and developers as possible are present. Thanks!
