Abstract
A system that visualizes a clock tree for an integrated circuit receives an extracted cell library, an extracted clock netlist including clock headers and interconnects, and simulation results. The system generates an internal data structure for the clock headers, and divides the clock headers into a plurality of levels based on the interconnects. The system then orders the clock headers from a lowest level to a highest level, and displays the ordered clock headers in an untangled manner.
