NEEDS (Nano-Engineered Electronic Devices Simulation) is a five-year NSF program charged to develop a suite of SPICE-compatible, compact models for emerging nanoelectronic devices. More importantly, NEEDS aims to create a complete model development environment (NEEDS-SPICE) to support the creation of high-quality compact models by technology developers and to provide designers with models that run robustly on both open source and commercial platforms. Most importantly, NEEDS aims to establish a framework for developing compact models a set of best practices and processes supported by a suite of educational resources and by the NEEDS-SPICE platform. By deploying these resources on nanoHUB.org, NEEDS will foster the integration of application-oriented device modeling with theoretical and experimental explorations. The goal is to support a community that will develop novel nanodevices for applications that address the challenges of 21st Century society. NEEDS is a partnership of materials scientists, device technologists, circuit designers, and application specialists. It is the electronics node of the Network for Computational Nanotechnology led by Purdue, MIT, and U.C. Berkeley and aiming to engage a global community.
The NEEDS-SPICE platform is being designed to address the barriers to creating high-quality, physics-based compact models for emerging nanodevices. This simulation-ready, open-source, compact model development environment will be Verilog-A compliant as far as possible, but it will go beyond Verilog-A with new capabilities needed for nanodevices. It will provide a complete environment for developing, testing, experimentally validating compact models and for inserting them in commercial and open source SPICE-compatible simulation platforms.
The four components of the NEEDS-SPICE platform are:
An alpha release of NEEDS-SPICE is planned for Summer 2014.
