            # LUT with FlipFlop Example


            An example of the classical LUT with FlipFlop pair.

            ## Blackbox detection


             - [ ] model of the leaf `pb_type` is generated

            
             - [ ] leaf `pb_type` XML is generated

            
             - [ ] all dependency models and `pb_type`s are included in the output files


            ## Carry chain inference


             - [ ] `pack_pattern` inference - `pack_pattern`s defined on wires with `pack` attributes should be propagated to `pb_type` XMLs
