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 â 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 â 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.
