An example of the classical LUT with FlipFlop pair.

This is shown in Figure 28 of the Architecture Reference section of the Verilog to Routing Documentation and reproduced below;

Figure 28 from Verilog to Routing Documentation Fig. 28 Pack Pattern Example.

Blackbox detection

  • [ ] model of the leaf pb_type is generated

  • [ ] leaf pb_type XML is generated

  • [ ] all dependency models and pb_types are included in the output files

Carry chain inference

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