Tandem with Field Updates designs are designs that use
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).
