Abstract

A segmented routing architecture includes three or more different interior segment lengths within all of the segmented tracks in a channel. Four or more different segment lengths of interior segments are present in a channel if the sole segment in each unsegmented track is considered, too. Two or more different segment lengths of interior segments exist within a single wiring track. Lengths of adjacent segments within a track are balanced with a ratio not exceeding about two. In any given channel, the average length of all the segments in each column is relatively low in the interior and increases substantially monotonically towards the ends of the channel.
