1. COPY text file by using textio pkg

  process
    file ifile : text is in "test.ccm";
    variable inbuf, outbuf : line;
    variable tempstr : line;
    variable lineno : integer := 0;
  begin

    while not endfile(ifile) loop
      lineno := lineno + 1;
      readline(ifile, inbuf);
      tempstr := new string'(inbuf.all);
      write(outbuf, lineno, right, 3);
      write(outbuf, string'(". "));
      write(outbuf, string'(tempstr.all));
      writeline(output, outbuf);
    end loop;

2. Bug: Can not set AddrA and AddrB

   Change the following part:

     addrA: parts.counterN generic map (18) port map
      ( reset=>reset, clk=>inc_addrA, ld=>ld_addrA, ce=>const_one,
                      ^^^^^^^^^^^^^^
        d=>ABus, q=>addrA_q );


   To:

     addra_clk <= inc_addrA or ld_AddrA;
     addrA: parts.counterN generic map (18) port map
      ( reset=>reset, clk=>addra_clk, ld=>ld_addrA, ce=>const_one,
        d=>ABus, q=>addrA_q );

   Why: Without clk signal, can not set AddrUnit by only "ld_addrA"
        see VHDL code for up-counter.
