Wire routing to control skew

A method for routing a signal from one of plural connection points to a pin so as to control skew, said method comprising:

• associating a diamond-shaped ring with each connection point, thereby defining a plurality of diamond-shaped rings, wherein each diamond-shaped ring includes an inner diamond, an outer diamond and all space between the inner diamond and the outer diamond, and wherein the inner diamond and the outer diamond have a common center which is the connection point associated with the diamond-shaped ring;
• determining which of the plurality of diamond-shaped rings include the pin;
• and
• routing a connection between the pin and the connection point associated with one of the diamond-shaped rings that includes the pin.

A method for routing a signal from an input terminal to a pin so as to control skew, said method comprising:

• constructing a pattern of diamond-shaped rings, each of the diamond-shaped rings including an inner diamond, an outer diamond and all space between the inner diamond and the outer diamond, wherein the diamond-shaped rings are arranged such that each point within a specified area is included within at least one diamond-shaped ring;
• identifying a center point for each of the diamond-shaped rings and designating each center point as a connection point;
• routing a nearly zero-skew connection between the input terminal and each of plural of the connection points;
• determining which of the diamond-shaped rings include the pin;
• and
• routing a connection between the pin and the connection point associated with one of the diamond-shaped rings that includes the pin,
• wherein the pattern comprises an arrangement of diamond-shaped rings such that the center points for the diamond-shaped rings are equally spaced in a horizontal direction and are equally spaced in a vertical direction.

Computer-executable process steps, stored on a computer readable medium, for pre-wiring a grid of connection points from an input terminal so as to control skew, said process steps comprising steps to:

• construct a pattern of diamond-shaped rings, each of the diamond-shaped rings including an inner diamond, an outer diamond and all space between the inner diamond and the outer diamond, wherein the diamond-shaped rings are arranged such that each point within a specified area is included within at least one diamond-shaped ring;
• identify a center point for each of the diamond-shaped rings and designate each center point as a connection point;
• and
• route a connection between the input terminal and each of plural of the connection points,
• wherein the pattern comprises an arrangement of diamond-shaped rings such that the center points for the diamond-shaped rings are arranged in a grid, equally spaced in a horizontal direction and equally spaced in a vertical direction.
