Verilog HDL: Ternary Adder Tree
This example describes a parameterized ternary adder tree in Verilog HDL. For devices which contain large lookup tables as combinational logic structures in logic element (LE) such as Stratix II, structuring adder trees as ternary adder trees can give significant performance improvement.
