Tandem with Field Updates designs are designs that utilize Dynamic Function eXchange flows. The Update Region is a Reconfigurable Partition, and each User Application that is inserted into that partition is a Reconfigurable Module. General debug within Reconfigurable Modules is now supported, and the example design that can be generated for any Tandem with Field Updates IP instance contains debug circuitry. The top level of the Reconfigurable Partition ( pci_app_uscale ) includes the boundary scan ports necessary for automatic insertion of the debug hub that permits debug cores to be instantiated within each Reconfigurable Module. Look for the S_BSCAN ports but do not change the pin names. For complete details, see Chapter 8 of Vivado Design Suite User Guide: Dynamic Function eXchange (UG909) [Ref 19] .
