Certify— A characterization and validation tool for behavioral models

Device modeling plays an important role in VLSI circuit design because computer-aided circuit analysis results are only as accurate as the models used. This indicates a need for robust tools that can facilitate the testing, validation and characterization procedure of semiconductor device models. Certify, the graphical tool for model characterization and validation, is a step in this direction [1]. The software architecture and different modules of Certify have been described in this paper.

1. Introduction

As semiconductor devices scale into the nanometer range, the fabrication process of these device structures becomes more time consuming and expensive. As a result, modeling is having an increasingly important role, as one can perform simulations much faster with much less cost, and different device geometries can be investigated before their actual fabrication.
