Multiplier Verilog Code — 3-bit

// Generate partial products (AND gates) assign pp0 = a[2] & b[0], a[1] & b[0], a[0] & b[0]; assign pp1 = a[2] & b[1], a[1] & b[1], a[0] & b[1]; assign pp2 = a[2] & b[2], a[1] & b[2], a[0] & b[2];

// Stage 3 full_adder fa2 ( .a(s1), .b(pp1[2]), .cin(c2), .sum(product[2]), .cout(c4) );
