  • Voltage island chip implementation
    Patent number: 6820240
    Abstract: A method and structure for designing an integrated circuit chip supplies a chip design and partitions elements of the chip design according to similarities in voltage requirements and timing of power states of the elements to create voltage islands. The invention outputs a voltage island specification list comprising power and timing information of each voltage island; and automatically, and without user intervention, synthesizes power supply networks for the voltage islands.
