U-turn circuitry to convert inter-layer connections of an integrated circuit device to intra-layer connections

Abstract

An integrated circuit (IC) device includes a block of integrated circuitry that includes functional circuitry and configurable interface circuitry. The configurable interface circuitry includes output circuitry that routes a node of the functional circuitry to an output node of the block, and input circuitry that selectively routes the output node of the block or an input node of the block to the functional circuitry. The output circuitry may route a selectable subset of multiple nodes of the functional circuitry to respective output nodes of the block, and the input circuitry may be configured to route the output nodes of the block back to the functional circuitry in the absence of an adjacent block (e.g., to repurpose the output circuitry), or in addition to interfacing with the adjacent block.
