Abstract: A method for modifying an integrated circuit and integrated circuits are provided. The method includes: providing an integrated circuit design comprising a plurality of circuit books having a first threshold voltage; and replacing at least one of the plurality of circuit books with at least one gate array book having a second threshold voltage that is lower than the first threshold voltage.

Abstract: Best and most recent NDR types are selected for all RLM's in a design in order to achieve timing closure. The selection employed uses two levels of filtering to examine the NDR types for each RLM, and based on the outcome of the filtering selects the most appropriate NDR type for input to the timing analysis. In one arrangement, the selection scheme is completely automated and is performed at the beginning of a timing analysis via script-driven processes.

Abstract: The invention relates to layout of circuit components, including determining the interconnections, buffers, or path nets between circuit blocks or circuit components and input/output bonding pads. This is accomplished by a method and program product that optimizes timing comprising. Wiring layout and buffer insertion is accomplished by setting all wires in the design to an initial best possible value, inserting buffers in longest nets of wires of the design, and degrading the resulting nets. This is accomplished by a wire sizing routine which takes the nets and degrades them accordingly. This degrading is done through a combination of one or more of knocking the wires down to lower levels and reducing their thickness. The amount of degradation is dependent on the final slack.
