Multiplier Usage

The Multiplier macros are present at:
<Install_Path>/conda/share/yosys/quicklogic

1. 32 x 32 Multiplier

• Configured as 1 32x32 multiplier

module MULT_32BIT (Amult, Bmult, Valid_mult, Cmult);
    input [31:0] Amult;
    input [31:0] Bmult;
    input  Valid_mult;
    output [63:0] Cmult;

    wire [1:0] valit_int;

    assign valit_int = {Valid_mult,Valid_mult};

    //qlal4s3_mult_cell_macro
    qlal4s3_mult_cell_macro u_qlal4s3_mult_cell_macro (.Amult(Amult), .Bmult(Bmult), .Valid_mult(valit_int), .sel_mul_32x32(1'b1), .Cmult(Cmult));
endmodule

2. 16 x 16 Multiplier

• Configured as 1 16x16 multiplier

module MULT_16BIT_X2 ( Amult1, Bmult1, Valid_mult1, Cmult1,
                       Amult2, Bmult2, Valid_mult2, Cmult2 );
    input [15:0] Amult1;
    input [15:0] Bmult1;
    input Valid_mult1;
    output [31:0] Cmult1;

    input [15:0] Amult2;
    input [15:0] Bmult2;
    input Valid_mult2;
    output [31:0] Cmult2;

    wire [31:0] amult_int;
    wire [31:0] bmult_int;
    wire [63:0] cmult_int;
    wire [1:0] valit_int;

    assign valit_int = {Valid_mult2,Valid_mult1};
    assign amult_int = {Amult2,Amult1};
    assign bmult_int = {Bmult2,Bmult1};
    assign Cmult1 = cmult_int[31:0];
    assign Cmult2 = cmult_int[63:32];

    //qlal4s3_mult_cell_macro
    qlal4s3_mult_cell_macro u_qlal4s3_mult_cell_macro (.Amult(amult_int), .Bmult(bmult_int), .Valid_mult(valit_int), .sel_mul_32x32(1'b0), .Cmult(cmult_int));
endmodule
