Spartan UltraScale+ devices do have ICAP resources, but they are reserved for the soft error mitigation (SEM) IP. Instead, the internal configuration access port is the AXI32 primitive, which provides a hardened AXI4 interface to the platform management controller. The AXI32 primitive can be accessed in IP integrator (IPI) with the PMC Bridge IP or using the XPM_PMC_BRIDGE module to instantiate AXI32 in the user design.

In addition to the AXI32 resource, the set of supported configuration modes are listed in Table 1.
Note: The MCAP connection is only available in larger
Spartan UltraScale+ devices (xcsu65p and
larger) that contain a
PCIe®
hard block.
