    摘要: A method and program product for optimizing level converter placement in a multi supply integrated circuit. Each level converter is placed at a minimum power point to minimize net power and transitional delay from a first (low) voltage net source through the level converter and to a second (higher) voltage net sink. Then, inefficient level converters are eliminated. Level converters with fanin cones below a selected minimum cone size are deleted and low voltage sources to the deleted level converter reverted. Higher voltage level circuit elements receiving inputs from multiple level converters are replaced with equivalent low voltage circuit elements. Low voltage buffer driving level converters are both replaced by a single said level converter.

    摘要: A level converter for interfacing two circuits supplied by different supply voltages, and integrated circuit including the level converter interfacing circuit in two different voltage islands. A first buffer is supplied by a virtual supply and receives an input signal from a lower voltage circuit. The first buffer drives a second buffer, which is supplied by a higher supply voltage. An output from the second buffer switches a supply select to selectively pass the higher supply voltage or a reduced supply voltage to the first buffer.

    摘要: An integrated circuit (IC) design, method and program product for reducing IC design power consumption. The IC is organized in circuit rows. Circuit rows may include a low voltage island powered by a low voltage (Vddl) supply and a high voltage island powered by a high voltage (Vddh) supply. Circuit elements including cells, latches and macros are placed with high or low voltage islands to minimize IC power while maintaining overall performance. Level converters may be placed with high voltage circuit elements.
