Abstract:
1. A processor-based method for validating a configuration bitstream used for partially reconfiguring an integrated circuit, the method comprising: configuring the integrated circuit with a first configuration bitstream, wherein the first configuration bitstream includes first bit values that produce an implementation of a static part of a design on the integrated circuit; determining whether any bit value in a second configuration bitstream is different from a corresponding bit value of the implementation of the static part of the design, wherein the second configuration bitstream includes second bit values that produce an implementation of a reconfigurable part of the design on the integrated circuit; outputting a first signal state in response to determining that no bit values in the second configuration bitstream are different from corresponding bit values of the implementation of the static part of the design; and outputting a second signal state in response to determining that one or more bit values in the second configuration bitstream are different from corresponding bit values of the implementation of the static part of the design.
