  • Multi-mode multi-corner clocktree synthesis
    Patent number: 9310831
    Abstract: A method for building a clock tree for an integrated circuit design. The clock tree has a plurality of clock tree nodes that couple to sink pins for circuit elements of the integrated circuit design to distribute the clock signal to the sink pins, which are clustered into one or more clusters. Timing information is determined to measure the clock signal delay from the root to the sink pins in the one or more clusters based on the placed one or more clock tree nodes. Different sets of timing information may be determined based on different sets of clock tree timing variation parameters.
