Choosing High-Speed Implementation for High-level Functional Module

• The designer can manually change the implementation selection specified synthetic library cell instances by setting the variable set_implementation as follows:

• Set_implementation <implementation_type> <cell_list>

• If A1 is an instance of the DW01_ADD cell in the current design, a cla carry-lookahead implementation can be specified to implement A1

• set_implementation cla A1
