  • Patent number: 9553581
    Abstract: A multi-module integrated circuit (IC) can be configured in different types of packages having different modules enabled or disabled. A module that can be disabled has driven circuitry that is known a priori to have a low-power input vector that places the driven circuitry into a low leakage power state. The module also has driving circuitry with one or more package-aware cells. The IC has a package-aware controller that generates control signals for the package-aware cells that ensure that the outputs from the package-aware cells are forced to particular values (i.e., either logical-0 or logical-1) that cause the low power input vector to be applied to the driven circuitry when the IC is assembled in a package in which the module is disabled. In this way, module leakage power is reduced for package types in which certain modules are disabled.
