Compact model development


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.

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.

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.
