A Field Programmable Gate Array (FPGA) device includes a plurality of input/output blocks (IOBs) and variable grain blocks (VGBs) An inter-connect network provides routing of signals between the IOBs and VGBs. The VGBs include a plurality of L-organized CBBs (configurable logic blocks) having function-producing...http://www.google.fr/patents/US6034544?utm_source=gb-gplus-shareBrevet US6034544 - Programmable input/output block (IOB) in FPGA integrated circuits
