Method for designing LSI system

摘要

A design technique considering a peak current is provided for high-level design of systems including LSIs. A hardware model representing the trade-off relationship between a leak current and performance is prepared in advance for functional units constituting the system. In the hardware model, the relationship between performance tpd and a source-drain leak current Pleak is described with a threshold voltage Vth as a parameter, for example. By referring to the trade-off relationship, design conditions for the functional units are determined under evaluation of the performance and power consumption of the entire system.
