Abstract

The presentation is a gentle introduction to compact models, basic circuit simulation concepts, and flows for developing compact models. The roadmap for the NEEDS-SPICE platform, being developed to ease the process of developing simulation-ready compact models for novel nanodevices, is briefly described.
