+Open Bus Interface (OBI)
+========================
+
+Implements the register block using an `OBI <https://github.com/openhwgroup/obi>`_
+CPU interface.
+
+The OBI interface comes in two i/o port flavors:
+
+SystemVerilog Interface
+    * Command line: ``--cpuif obi``
+    * Interface Definition: :download:`obi_intf.sv <../../hdl-src/obi_intf.sv>`
+    * Class: :class:`peakrdl_regblock.cpuif.obi.OBI_Cpuif`
+
+Flattened inputs/outputs
+    Flattens the interface into discrete input and output ports.
+
+    * Command line: ``--cpuif obi-flat``
+    * Class: :class:`peakrdl_regblock.cpuif.obi.OBI_Cpuif_flattened`
