FPGA REDUNDANCY

摘要

An FPGA includes primary resources and redundant resources. To program an FPGA to perform a desired function, a pattern of programmable elements to be programmed that takes advantage of primary resources only is first prepared. This pattern is then modified responsive to previously obtained information about defects within the FPGA. The modified pattern takes advantage of redundant resources as direct or indirect substitutes for FPGA elements rendered unusable by defects. The FPGA is programmed in accordance with the modified pattern.
