Hi Chr_sue, like you said timing related to do in driver, So a task is created for reading the text file in the driver class.

//task for reading txt file in driver
 task read_image_2_hex();
      
    #1009.700ns $readmemh("./image_2_hex.txt", this.temp_mem); 
    if(vif.i_pixel_enable==1'b1) begin   
    for(int i=0;i<2000;i++) begin
    @(posedge vif.i_Pixel_clock);
    arinc_818_tx.i_pixel_data   <= this.temp_mem[i];
    $display("read_file_drv --> temp_mem[%0d] = %h",i,this.temp_mem[i]);
    $display("read_file_drv --> i_pixel_data[%0d] = %h",i,arinc_818_tx.i_pixel_data[i]); //not able to take the value from temp_mem to i_pixel_data
     end
    end
   endtask

// driver task run_phase
  wait(vif.i_reset_n == 1'b1) begin :B3
       fork            
            @(posedge vif.i_Pixel_clock) drive_pxl(arinc_818_tx);
             read_image_2_hex();
            @(posedge vif.i_sys_clock) drive_frmr(arinc_818_tx);
        join
      end :B3
   
endclass :driver
