Abstract:
1. A semiconductor integrated circuit design support system having a partial power control mechanism, comprising: a partial power control simulation section configured to perform a partial power control simulation on the basis of a circuit description of the semiconductor integrated circuit and a power specifications description; a power mode detection section configured to detect a power mode which is run during execution of the partial power control simulation and record a plurality of pieces of power mode information in transitions of the power mode as power mode information of an examined power mode, the power mode being defined by a state of a plurality of power control signals for a plurality of power domains which are allowed to be powered off in the semiconductor integrated circuit, and the plurality of pieces of the power mode information including information on the state of the plurality of power control signals in the transitions of the power mode; and a power mode check section configured to check whether the examined power mode recorded by the power mode detection section is used at the time of execution of partial power control by the semiconductor integrated circuit according to a partial power control program and output a check result thereof, by comparing information of a power mode detected at the time of execution of the partial power control with the power mode information of the examined power mode.
