Key technologies and international trends in EDA field of digital IC design: a patent analysis

Abstract

Currently, Electronics Design Automation (EDA) software tools are highly monopolized internationally. In China, EDA suffers from the pain of “stuck neck”. This paper will find out the key technologies in the EDA field through 3D sand table clustering algorithm, and analyze a series of patent data of monopoly three companies (Synopsys, Cadence, Mentor Graphic), in order to help local EDA enterprises perceive the technology status and development trend of the international EDA field.
