Abstract: A design tool with a direct current (DC) transformation analysis unit determines combinations of candidate sink locations for sector buffers within a sector of a clock network design. For each of the combination of candidate sink locations, the design tool transforms resistances of the sector with the combination of candidate sink locations into resistances of an electrical circuit. The design tool transforms capacitances of the sector with the combination of candidate sink locations into current sources of an electrical circuit. The design tool performs a DC circuit analysis, wherein results of the DC circuit analysis include a variance of voltage at nodes of the sector and a maximum value of current from currents flowing between pairs of the nodes of the sector. The design tool determines which of the combination of candidate sink locations has the minimum variance of voltage with the results of the DC circuit analysis.

Abstract: An electronic automation design tool with a sink locator unit creates clusters of loads from a plurality of loads within a sector of a clock network design based on balancing magnitudes of the loads among the clusters of loads and based on minimal delays of each of the clusters and respective ones of a plurality of sink locations in the sector of the clock network design. The tool determines centers of the clusters of loads, and sink locations corresponding to the centers of the clusters for connecting output terminal points of sector buffers are determined. Each of the sector buffers drive a clock signal to a corresponding one of the clusters of loads.
