Combinational DSP
+++++++++++++++++

A combinational DSP block capable of multiplication and division. Modeled as "combinational block" according to |fig60|_ of `Primitive Block Timing Modeling Tutorial <https://docs.verilogtorouting.org/en/latest/tutorials/arch/timing_modeling/#primitive-block-timing-modeling-tutorial>`_.

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
