Abstract
Method and apparatus for controlling power in an emulation system is described. In one example, power is controlled in a processor-based emulation system coupled to a host computer. A logic design is processed to identify unused resources in the emulation system during an emulation cycle. Power of the unused resources is controlled during emulation of a design under verification corresponding to the logic design by the emulation system. The resources may be identified as being unused during one or more steps of the emulation cycle. The power of the unused resources may be controlled by at least one of: powering down one or more of the unused resources; disabling one or more of the unused resources; freezing inputs to one or more of the unused resources; or setting inputs to one or more of the unused resources to a constant state. In this manner, power consumption of the emulation system is reduced.
