Abstract
Approaches for validating a configuration bitstream used for partially reconfiguring an ingrated circuit such as a programmable logic device (PLD) are disclosed. In one approach, the integrated circuit is configured with a first configuration bitstream that includes first bit values that produce an implementation of a static part of a design on the integrated circuit. Any differences between a bit value in a second configuration bitstream and a corresponding bit value of the implementation of the static part of the design are determined. The second configuration bitstream includes second bit values that produce an implementation of a reconfigurable part of the design on the integrated circuit. A first signal state is output in response to determining that there are no differences, and a second signal state is output in response to determining that there are differences.
