SYSTEM ON CHIP (SOC), AND DYNAMIC VOLTAGE FREQUENCY SCALING (DVFS) VERIFICATION METHOD THEREOF

摘要

A dynamic voltage and frequency scaling (DVFS) verification method of a system on chip according to an exemplary embodiment of the disclosed subject matter includes extracting, by a DVFS state extraction module, a DVFS state conversion code from a code, analyzing the extracted DVFS state conversion code, and generating a DVFS state value according to a result of the analysis, generating, by a valid state extraction module, valid state values which satisfy an operation voltage condition and an operation frequency condition capable of operating the system on chip, and determining, by a stability determination module, stability of the DVFS state value according to whether or not the DVFS state value is equal to one of the valid state values.
