If the boundary between static (PS) and dynamic (PL) is specifically at the PS-PL interface, the following use cases apply:

  • If the entire PL is included in the dynamic region, partial reconfiguration includes a power domain shutdown such that the entire PL is temporarily powered down.
  • The static design should include the functional behavior required for the data and interface management. It can implement mechanisms such as handshaking or disabling interfaces, which might be required for bus structures to avoid invalid transactions. It is also useful to consider the down-time performance effect of a dynamic module, that is, the unavailability of any shared resources included in the dynamic module during or after reconfiguration. This is the most common scenario.
