can we delay read and write transactions(axi4) by providing delay in register slice?

Basically I want to provide delay of 15 clock cycles  for writing and reading through axi4 bus .Is it possible?

  • Hello,


    I think your code might support only the 4 burst case from the description below.

    always @(posedge clk) begin
      if (w_complete_ns | reset) begin
        cnt <= {C_CNT_WIDTH{1'b1}};
      end else if (whandshake_i) begin
        cnt <= cnt - 1'b1;
      end
    end
    always @(posedge clk) begin
      if (reset | w_complete_ns) begin
        subburst_last <= 1'b0;
      end else if ((cnt == {{C_CNT_WIDTH-1{1'b0}},1'b1}) & whandshake_i) begin
        subburst_last <= 1'b1;
      end
    end
