Abstract
According to one or more embodiments of the present invention, a computer-implemented method includes determining, for a first sector from multiple sectors of a clock mesh of a semiconductor circuit, a set of mesh wires. The method further includes generating tapping point candidates, selecting a first combination of tapping points, and performing an analog electrical simulation of a clock signal. The simulation includes feeding the clock signal into the clock mesh via the first combination of tapping points via a clock signal transmitter, and measuring delays for the clock signal to reach a set of measuring nodes. The maximum delay from the measured delays is selected, and, in response to the maximum delay being less than a previous delay value, the first combination of tapping points is used to connect sector buffers from the first sector to the clock mesh.
