Abstract:
1. A method for designing a system including an LSI at a system design level, the method comprising the step of: determining design conditions for respective functional units constituting the system under evaluation of processing time and power consumption of the entire system, wherein the step of determining design conditions comprises the steps of: implementing the functional units constituting the system by software to evaluate the processing time and power consumption of the entire system; preparing in advance a hardware model representing a trade-off relationship between a leak current and a processing time for at least one of the functional units; implementing said at least one of the functional units by hardware to evaluate the processing time and power consumption of the entire system; and determining the design conditions for said at least one of the functional units by referring to the trade-off relationship represented by the hardware model so that the processing time of the entire system satisfies at least one predetermined specification.
