SPICE-based Tool for Static CMOS Propagation Time Extraction

Abstract

This paper presents one possible solution for building the propagation time extraction tool. Developed tool may help engineers to extract necessary parameters for the system level modeling of the propagation time when the integrated circuit, static CMOS, implementation is intended. Proposed Electronic Design Automation (EDA) solution is built using the free/open-source software which ensures zero cost and high flexibility. Two known concepts for extracting key parameters of propagation time model are presented. The set of parametric simulations has been performed in order to cross-compare presented concepts using the developed EDA tool.
