Date of current version: 24 January 2022

Last summer 2021, the IEEE Solid-State Circuits Society (SSCS) launched its first open source chip design contest under the umbrella of its Platform for Integrated Circuit Design Outreach program (PICO). Beginning with 61 submissions, a volunteer jury selected 18 teams from nine countries to embark on a journey toward tapeout. Anyone interested in supporting future activities is encouraged to sign up at the Society’s volunteer web portal. Stay tuned for the 2022 edition of the SSCS PICO contest!

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

In 28th MIXDES (2021), pp. 35-40 

DOI: 10.23919/MIXDES52406.2021.9497545 

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.

Abstract: The ability to carry out simulations before making a PCB can save a lot of time, effort and cost. This work explains the creation of an open source mixed-signal simulation software eSim that will be of great help to students, hobbyists, the SME sector and startups. Analog and digital components are respectively modelled using SPICE and a hardware descriptive language in eSim. Inclusion of AVR based microcontroller as a part of the digital circuit is demonstrated through its instructions implemented as a C code library. This methodology could be used to provide support to other microcontroller families, such as PIC, STM and also more sophisticated controllers. These concepts are demonstrated through a few examples.

How to support open-source software and stay sane

Anna Nowogrodzki

DOI: https://doi.org/10.1038/d41586-019-02046-0

Releasing lab-built open-source software often involves a mountain of unforeseen work for the developers.

It’s a familiar problem: open-source software is widely acknowledged as crucially important in science, yet it is funded non-sustainably. Support work is often handled ad hoc by overworked graduate students and postdocs, and can lead to burnout [read more...]

Nano-Electronic Simulation Software (NESS): 

A Novel Open-Source TCAD Simulation Environment

Journal of Microelectronic Manufacturing

Vol 3 (4) : 20030407 2020

DOI:  10.33079/jomm.20030407

Abstract: This paper presents the latest status of the open source advanced TCAD simulator called Nano-Electronic Simulation Software (NESS) which is currently under development at the Device Modeling Group of the University of Glasgow. NESS is designed with the main aim to provide an open, flexible, and easy to use simulation environment where users are able not only to perform numerical simulations but also to develop and implement new simulation methods and models. Currently, NESS is organized into two main components: the structure generator and a collection of different numerical solvers; which are linked to supporting components such as an effective mass extractor and materials database. This paper gives a brief overview of each of the components by describing their main capabilities, structure, and theory behind each one of them. Moreover, to illustrate the capabilities of each component, here we have given examples considering various device structures, architectures, materials, etc. at multiple simulation conditions. We expect that NESS will prove to be a great tool for both conventional as well as exploratory device research programs and projects.

A comparative computational study of tunneling transistors

based on vertical graphene–hBCN heterostructures

ABSTRACT In this paper, the electrical characteristics of tunneling transistors based on vertical graphene and a hexagonal boron-carbon-nitrogen (hBCN) heterostructure are studied and compared theoretically. We have considered three different types of hBCN, i.e., BC₂N, BC₂N₀, and BC₆N as a tunneling barrier. Our simulation is based on the nonequilibrium Green’s function formalism along with an atomistic tightbinding (TB) model. The TB parameters are obtained by fitting the band structure to first-principles results. By using this method, electrical characteristics of the device, such as the ION=IOFF ratio, subthreshold swing, and intrinsic gate-delay time, are investigated. For a fair comparison, the effects of geometrical variations and number of tunneling barrier layers on the electrical parameters of the device are simulated and investigated. We show that, by an appropriate design, the device can be used for low-power or high-performance applications. The device allows current modulation exceeding 106 at room temperature for a 0.6 V bias voltage.

[FOSSi] OpenLANE: Open Source 130nm PDK

Join Mohamed Shalan for the 2nd talk in the Free and Open Source Silicon (FOSSi) Foundation Dial-Up series is on Tuesday 28th July, he will talk about OpenLANE on the first-in-the-industry Open Source Manufacturable SkyWater 130nm PDK

Mohamed Shalan - OpenROAD on SkyWater 130nm

Unlike the wider software world, Electronic Design Automation (EDA) open-source landscape has been fragmented for a long time, requiring significant effort and knowledge in a variety of disciplines to assemble a working ASIC flow. This has changed with projects such as Qflow and OpenROAD that aim at developing open-source toolchain for digital layout generation from RTL. OpenLane is an automated RTL to GDSII flow based on available opensource EDA tools configured/tuned for the SkyWater 130nm PDK. OpenLane main objective is to generate a clean layout from RTL designs in less than 24-hours with zero human interventions. OpenLane has been used, successfully, to tape-out a family of test chips (striVe).

FOSS EKV 2.6 Parameter Extractor

22nd International MIXDES Conference, pp. 181-186 (2015)

Abstract: The design of advanced integrated circuits (IC) in particular for low power analog and radio-frequency (RF) application becomes more complex as the device level modeling confronting challenges in micro- and nano-meter CMOS processes. As present CMOS technologies continue geometry scaling the designers can benefit using dedicated SPICE MOSFET models and apply specific analog design methodologies. The EKV was developed especially to meet altogether the analog/RF design requirements. This paper describes a basic set of the DC parameter extraction steps for the EKV 2.6 model. The free open source software (FOSS) Profile2D tool was used to illustrate an accurate EKV 2.6 DC extraction strategy.

Abstract - A GNU Octave - based application for device-level compact model evaluation and parameter extraction has been developed. The applications main features are as follows: experimental I–V data importing, generating input data for different circuit simulation programs, running the simulation program to calculate I–V characteristics of the specified models, calculating model misfit and its sensitivity to selected parameter variation, and the comparison of experimental and simulated characteristics. Measured I–V data stored by different measurement systems are accepted. Circuit simulations may be done with Ngspice, Qucs and LTSpiceIV © . Selected aspects of the application are presented and discussed.
