11.4.1.7. Potential Incompatibility between RTL Modules and Partial Reconfiguration

When you create an HLS library using RTL modules, you might encounter Partial Reconfiguration-related issues.

Consider a situation where you create and verify your library on a device that does not support Partial Reconfiguration (PR). If you then use the library RTL module inside a PR region, the module might not function correctly after PR.

To ensure that the RTL modules function correctly on a device that uses PR:
  • The RTL modules do not use memory logic array blocks (MLABs) with initialized content.
  • The RTL modules do not make any assumptions regarding the power-up values of any logic.

For complete PR coding guidelines, refer to Creating a Partial Reconfiguration Design in the Partial Reconfiguration User Guide.
