// Row 0 Logic (First layer of adders) // We add pp[0][k] with pp[1][k] // This is complex to wire manually without generate blocks. // Below is a structural representation of the addition stages. initial begin // Initialize Inputs A = 0; B = 0; task test_multiply(input [7:0] a_val, b_val); begin @(posedge clk); A = a_val; B = b_val; start = 1; @(posedge clk); start = 0; wait(done); $display("A=%d, B=%d, P=%d (Expected: %d)", a_val, b_val, P, a_val * b_val);

• $Sum = A \oplus B \oplus C_in$
• $C_out = (A \cdot B) + (C_in \cdot (A \oplus B))$

Run with:

            A7 A6 A5 A4 A3 A2 A1 A0   (8 bits)
         ×  B7 B6 B5 B4 B3 B2 B1 B0   (8 bits)
         ---------------------------
            A×B0 (shifted 0)  → 8 bits
           A×B1 (shifted 1)   → 9 bits (with overflow)
          A×B2 (shifted 2)    → 10 bits
              ...
         A×B7 (shifted 7)     → 15 bits
         ---------------------------
         Sum of all → 16-bit product
