以下是将该段代码转换为Verilog代码的示例：

// Define module and input/output ports
module fft_module(
  input clk,
  input rst,
  input inValid,
  input signed [dataWidth-1:0] dataIn_re,
  input signed [dataWidth-1:0] dataIn_im,
  output reg busy,
  output signed [dataWidth-1:0] [0:stageNum] stageIntf1,
  output signed [dataWidth-1:0] [0:stageNum] stageIntf2
);

// Define parameters
parameter FFTLength = 64;
parameter dataWidth = 16;
parameter binaryPoint = 8;

// Calculate stageNum and dCount
localparam stageNum = $clog2(FFTLength) - 1;
reg [log2Ceil(3*FFTLength+stageNum)-1:0] dCount;
initial dCount = 0;

// Calculate busy signal
always @(posedge clk, posedge rst) begin
  if (rst) begin
    dCount <= 0;
    busy <= 0;
  end else begin
    if (inValid || (dCount != 0)) begin
      if (dCount == (3.5*FFTLength+stageNum-1)) begin
        dCount <= 0;
      end else begin
        dCount <= dCount + 1;
      end
      busy <= 1;
    end else begin
      busy <= 0;
    end
  end
end

// Calculate stageIntf1 and stageIntf2
always @(*) begin
  for (genvar i = 0; i <= stageNum; i++) begin
    stageIntf1[i] = 0;
    stageIntf2[i] = 0;
  end
  // Pre-stage
  reg [dataWidth-1:0] commutatorReturn [0:1];
  {commutatorReturn[0], commutatorReturn[1]} = Commutator(dataIn_re, dataIn_im, dCount[0], 1);
  stageIntf1[0] = commutatorReturn[0];
  stageIntf2[0] = commutatorReturn[1];
end
