Detection of combinational connections
**************************************

* Output has combinational connection with input

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
