1.6. Bitstream Compatibility Check

Turn on the Enable bitstream compatibility check when instantiating the PR Controller IP core from either Platform Designer or the IP Catalog for supported devices. The software then verifies the partial reconfiguration PR Bitstream file (.rbf). If an incompatible bitstream is detected, the PR operation stops, and the status output reports an error. The PR .pof ID encodes as the 71st word of the PR bitstream.

Figure 6. Bitstream Compatibility Check

This option prevents you from accidentally corrupting the static region of your design with a bitstream from an incompatible .rbf and risking damage to the chip you are programming.

When you turn on Enable bitstream compatibility check, the PR Controller IP core creates a PR bitstream ID and displays the bitstream ID in the configuration dialog box.
