ABSTRACT:
A programmable integrated circuit includes configurable logic blocks (CLB's), configurable input/output blocks (IOB's) and a configurable interconnect network for providing program-defined routing of signals between the CLB's and IOB's. A selector is provided with each of peripherally distributed IOB's of each row or column for selecting an output signal from plural one of long lines that extend perpendicularly relative to the peripheral boundary at which the IOB resides.
