A method for computing a position for a zero-skew driver insertion point in an area occupied by nodes driven by the driver is described. The zero-skew driver insertion point is the position in the area where the spread of the signal arrival times at the nodes driven by the driver is minimized. The method includes: expressing a function describing a distance from each of the nodes to the zero-skew driver insertion point, expressing the variance of the function, minimizing the variance of the function, and solving an equation representative of the minimization of the variance of the function to determine the position of the zero-skew driver insertion point. In one embodiment, the minimizing the variance of the function includes: taking a first derivative of the function with respect to the distance, and setting the first derivative of the function to zero.
