A method for making a bump and trace layout for an integrated circuit die includes the step of replicating a routing tile having a first column of I/O pads and a second column of I/O pads wherein the first column is offset from the second column so that the I/O pads of the first column are interleaved between the I/O pads of the second column.

Skew is reduced in a tree-shaped distribution network having plural levels and plural nodes at each level, where a node at one level connects to plural nodes at the next lower level. Initially, the current level is set to the bottom level of the network. Delay ranges are then obtained corresponding to nodes at the current level and the delay ranges are shifted in an attempt to align delay ranges corresponding to nodes at the current level that connect to the same node at the next higher level. These steps are then repeated for all levels in order from the bottom level to the top level.
