1. INTRODUCTION: ESD Extractor
ESD is an extremely fast discharging phenomenon occurring when two charged objects are brought into proximity and electrostatic charges transfer in between [1]. In order to avoid ESD damages, ESD protection circuits are required for practical IC products [1]. An ESD protection layout extractor is critically important to chip level ESD protection design verification since it makes it feasible to perform further layout-schematic checking and ESD circuit simulation at whole chip level.
