Abstract

The present invention is directed to laying out connection points and routing a signal from an input terminal to the connection points for use in signal distribution to control skew. A pattern of diamond-shaped rings is constructed, each of the diamond-shaped rings including an inner diamond, an outer diamond and all space between the inner diamond and the outer diamond, where the diamond-shaped rings are arranged such that each point within a specified area is included within at least one diamond-shaped ring. A center point is identified for each of the diamond-shaped rings and each center point is designated as a connection point. A connection is then routed between the input terminal and each of plural of the connection points. The invention also is directed to routing a signal from one of plural connection points to a pin so as to control skew. A diamond-shaped ring is associated with each connection point, the diamond-shaped ring including an inner diamond, an outer diamond and all space between the inner diamond and the outer diamond, where the inner diamond and the outer diamond have a common center which is the connection point associated with the diamond-shaped ring. It is then determined which of the diamond-shaped rings include the pin. Finally, a connection is routed between the pin and the connection point associated with one of the diamond-shaped rings that includes the pin.
