The DUT Component View in VerifStudio, shows you all the different ports in the design grouped into interface specifications.  The port and the interface specifications are obtained from the IPXACT specification of the DUT. IPXACT is an IEEE standard (IEEE-1685-2014) for specification of any IP block and it includes three sections. . 

1.  List of all the ports in the design.
2.  List of all the protocol interfaces -  includes a list of port maps (i.e, physical port on the DUT to the logical port on the protocol interface). 
3. List of all the registers and memory blocks - specifications of each register including the set of fields, the access policies for each field, and the address map for the registers.
