How to Design a Multiplier Circuit using AHDL?

Hi all: I have a multiplier circuit built using Multisim and I suppoosed to use AHDL to implement the circuit. Problem is, I don't know where to begin and how to actually use the circuit. Here ar...

Step 1: Go to your tutor and tell him that AHDL is an old and unsupported language. From Quarus 10 you wont be able to simulate it at all.

Step 2: Do it in a more modern HDL like VHDL or Verilog that are IEEE standard, not proprietry, languages.

Otherwise: 


MultiplierA :    lpm_mult    WITH (    LPM_WIDTHA                                = 2 , 
                                            LPM_WIDTHB                                 = 2 ,
                                            LPM_WIDTHP                                 = 4 ,
                                            LPM_WIDTHS                                 = 1 ,
                                            LPM_REPRESENTATION                         = "UNSIGNED" ,
                                            LPM_PIPELINE                             = 1 ,
                                            INPUT_A_IS_CONSTANT                     = "NO" ,
                                            INPUT_B_IS_CONSTANT                     = "NO" ,
                                            USE_EAB                                     = "OFF"  ,
                                            DEDICATED_MULTIPLIER_CIRCUITRY             = "YES"
                                        ) ;
MultiplierA.clock = clk;
MultiplierA.clken = VCC;
MultiplierA.dataa = input1;
MultiplierA.datab = input2;
output = MultiplierA.result;
