D-Flipflop with one clock
+++++++++++++++++++++++++

The following shows a simple D-flip flop driven by one clock. ``input wire a`` should be detected as a clock because it drives the flip flop.

As you can see in the generated model, the ``is_clock`` attribute of the ``a`` port is set to 1, while the ``b`` and ``c`` ports have their ``clock`` attribute set to ``a``.
