Abstract
Approaches for mitigating single event upsets (SEUs) in a circuit arrangement. In response to each bit error of a plurality of bit errors, an error address indicative of the bit error in a configuration memory cell in the circuit arrangement is translated into a non-volatile memory address. A partial bitstream at the non-volatile memory address is read from a non-volatile memory. Successive partial bitstreams read in response to successive ones of the bit errors are alternately transmitted to first and second internal configuration ports. A subset of configuration memory cells of the circuit arrangement, including the configuration memory cell referenced by the error address, is reconfigured with the partial bitstream.
