Systems and methods for providing defect recovery in an integrated circuit

Abstract:

A programmable logic device includes an integrated circuit die having a programmable fabric region including N identical programmable logic partitions. In some embodiments, N-1 of the identical programmable logic partitions are user-programmable. In addition, and in some cases, one of the identical programmable logic partitions is a spare logic partition. In some embodiments, the integrated circuit die further includes a network-on-a-chip (NOC) including a vertical NOC (VNOC) and a horizontal NOC (HNOC). By way of example, the N identical programmable logic partitions are configured to communicate exclusively through the NOC. In some embodiments, a defective one of the N-1 identical programmable logic partitions is configured for swapping with the spare logic partition.
