SEMICONDUCTOR CIRCUIT DESIGN SUPPORTING APPARATUS AND METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM

摘要

A semiconductor circuit design supporting method includes: reading Register Transfer Level (RTL) description circuit data; generating an equivalent circuit corresponding to the RTL description circuit data; extracting a plurality of arithmetic components included in the generated equivalent circuit; clustering some of the extracted arithmetic components as a single arithmetic component, wherein no storage element exists between said some of the extracted arithmetic components; reading a timing constraint on the RTL description circuit data; tracing an exception path of the RTL description circuit data when the timing constraint includes a timing exception; determining whether or not the timing exception is set for input pins of said some of the arithmetic components which are clustered as the single arithmetic component, based on the traced exception path of the RTL description circuit data; and separating a arithmetic component for which the timing exception is set, from said some of the arithmetic components which are clustered as the single arithmetic component.
