  • Timing-driven integrated circuit layout through device sizing
    Patent number: 5654898
    Abstract: A method and apparatus for determining the layout of an integrated circuit, in accordance with timing constraints, by means of sizing the buffers in the layout. A nominal netlist for the layout of the integrated circuit is used to determine critical paths through the circuit. The time-critical paths are determined and the instances of the buffers along the path are resized so that the time delays in the time-critical paths are either brought within the predetermined timing criteria, or no further improvement in any time-critical path is possible.
