A set of high speed interconnect lines for an integrated circuit has an improved line-to-line capacitance and overall RC time constant. The high speed interconnect line set incorporates a series of interconnect lines, wherein shorter run lines are routed between longer run lines. As the short run interconnect lines reach their destination and fall away they open up the line spacing and improve the line-to-line capacitance that dominates capacitive effects in modern reduced feature size integrated circuits. Additionally, the cross sectional area of the interconnect lines can be increased to lower the line resistance of longer run lines and compensate for the line capacitance without increasing the line-to-line capacitance. The capacitances, resistances, and RC time constants can be optimized for a single line of a group or for the entire group of interconnect lines, providing a low average value or a uniform value across all lines for uniform propagation delay.
