 - The ``clkbuf_driver`` attribute can be set on an output port of a blackbox

+- The ``clkbuf_inhibit`` is the default attribute to set on a wire to prevent
+  automatic clock buffer insertion by ``clkbufmap``. This behaviour can be

+- The ``iopad_external_pin`` attribute on a blackbox module's port marks
   it as the external-facing pin of an I/O pad, and prevents ``iopadmap``
   from inserting another pad cell on it.
