DCFIFO Megafunction simulation problem

i've the attached the waveform and here the test-bench code

`timescale 1ps/1ps
module tb_dc_fifo();
  
reg wr_clk, rst, rd_clk;
reg  data;
reg rdreq, wrreq;
wire  q, data_out;
wire rdempty, rdreq_o;
initial 
  begin
    
    wr_clk = 1'b0;
    rd_clk = 1'b0;
    data =45'h0AAAAAAAAAAA;
    rst  = 1'b1;# 45 rst  = 1'b0;
    rdreq = 1'b0;
    wrreq = 1'b1;
    
  end
always# 100  wr_clk = ~wr_clk;  
always# 5    rd_clk = ~rd_clk;
