Compact model development
MOS-AK workshop 2015 2
Community building -education, -nanoHUB presence, workshops, etc.
Specific goals
1) Develop a suite of open-source, physics-based compact models for emerging nanodevices.
2) Create tools and processes for developing compact models.
3) Develop educational resources to support 1) and 2).
4) Leverage nanoHUB.org to to engage a broad community of device researchers and designers.

NEEDS compact model
MVS 1.0.1 Nanotransistor Model (Silicon) By Shaloo Rakheja, Dimitri Antoniadis (MIT)
Model Release Components: • MVS Model 1.0.1 in Verilog-A • MVS Model Circuit Simulation Benchmarks • MVS Model Exerciser in MATLAB • MVS Model Parameter Extractor in MATLAB • MVS Model Manual • Experimental Data from Intel 32 nm and 45 nm N-type devices • Details of changes in this version • The model release components are licensed under a modified CMC license. Licensing
Abstract— The MIT Virtual Source (MVS) model is a semi-empirical compact model for nanoscale transistors that accurately describes the physics of quasi-ballistic transistors with only a few physical parameters.

Development of VAlint
MOS-AK workshop 2015
Prototype: VAChecker (2014) • Based on ADMS • Check for single Verilog-A file only. • Simple text based output
Today: VALint BETA (since Sep. 1st, 2015) • Support models with multiple Verilog-A
files. • Text editor interface with VALint
integrated. • To be an integrated part of NEEDS
publication curation. 14

Summary
Year 1 Put the pieces in place
Year 2 Deploy MAPP within NEEDS Deploy first set of resources
Years 3-4 (Current)
Release MAPP/grow resource base Engage the external community
Year 5 “Finalize” • Educational and training resources • Publication processes • Tools (MAPP, VALint, model exerciser)
Year 6 Transition
• A broad suite of physics-based compact models for emerging nanodevices. • A powerful set of open source tools for developing “simulation-ready” compact models. • A set of open educational resources that: i) help beginners develop simulation-ready
compact models and ii) convey the physical principles of nano-device operation. • A community of students and faculty that are better able to work from end-to-end
across the technology spectrum. • Demonstration of the value of “compact modeling” in research and technology
development.
