Further power consumption control is provided to the user by allowing them to shut down the transceivers, PCIe hard IP, and supporting circuitry to minimize power consumption when not used. Quartus® II will automatically power down unused transceivers and the user can dynamically power down any of the sub-blocks available through the signals listed in the table on this slide. It should be noted that there will be a leakage current for the “powered down” blocks which will be an order of magnitude lower than the operating current.
