Abstract
A special interconnect circuit which connects adjacent configurable logic elements (CLEs) in a configurable logic array (CLA) without using the general interconnect structure of the CLA. In one embodiment, an array of CLEs is arranged in rows and columns and a special vertical lead circuit is provided which connects an output lead of a given CLE in a given column to a selected input lead of the CLE above it and below in the same column. Special horizontal lead circuits are provided which connect a given output lead of a given CLE to a selected adjacent input lead of the CLE in the same row.
