Abstract
On-chip ESD (electrostatic discharging) protection is a challenging IC design problem. New CAD tools are essential to ESD protection design prediction and verification at full chip level. This paper reports a novel concept and extraction method of ESD-critical parameters for function-based layout-level ESD protection circuit design verification, which has been used to develop the first intelligent CAD tool of such kind. Design examples in 0.35μm BiCMOS are presented.
