Clock associations inference
****************************

* Automatic inference is signal is associated with any clock and include the info in the model
* Automatic clock detection (signals named ``clk`` are considered as clocks)

Blackbox detection
******************

* Model of the leaf ``pb_type`` is generated
* Leaf ``pb_type`` XML is generated

Timings
*******

* All the timings defined for wires with attributes should be included in ``pb_type`` XML
