  An algebra-logical repair method for FPGA functional logic blocks on the
basis of solving the coverage problem is proposed. It is focused on
implementation into Infrastructure IP for system-on-a chip and
system-in-package. A method is designed for providing the operability of FPGA
blocks and digital system as a whole. It enables to obtain exact and optimal
solution associated with the minimum number of spares needed to repair the FPGA
logic components with multiple faults.
