摘要： A power planning phase module, a placement phase module, and a routing phase module are provided that can replace, supplement, or enhance existing electronic design automation (EDA) software tools. The power planning phase module adds distributed power sources and a network of switching elements to the power frame or ring assigned to regions of a chip (that may be identified during a floor planning stage). The placement phase module optimizes a number and type of cells attached to each power source of the distributed power sources already added or to be added during the power planning phase. The routing phase module optimizes routing length to, for example, mask power consumption.

摘要： A floating core network for secure isolation of a circuit from an external supply interface is described. Isolation of a core is accomplished through a dynamic current limiting network providing an isolated core voltage to the core; and an isolated supply for the corresponding core that is continuously recharged by the dynamic current limiting network. The dynamic current limiting network can include two control loops, one control loop providing a fixed gate voltage to a p-type transistor supplying current to the isolated supply and another control loop providing a fixed gate voltage to an n-type transistor sinking current from the isolated supply.

摘要： Advantageous analog and/or digital logic cells and methods of powering circuit blocks using the same are provided. A digital logic cell can include a charge storage device, a logic block, and connections to a power supply. The charge storage device may be a capacitor. The capacitor or other charge storage device can be disconnected from the logic block and a power supply to discharge the capacitor, and then connected to the power supply, via the power supply connections, to charge the capacitor. The capacitor can be disconnected from a ground connection of the power supply while the capacitor is discharged. After being charged via the power supply, the capacitor can also be disconnected from the power supply (including ground) and connected to the logic block to power the logic block.
