    should be easy to write in TCL.

    Mif files are read at compile time, so there would be no use in reading the text from a .mif file in compiled VHDL.

    Unless this is for a testbench?

    I would recommend using Intel .hex file format. Its easy to generate using C code, and easy to parse in a testbench directly.

    Wikipedia has the format of .hex files.

    http://en.wikipedia.org/wiki/intel_hex

    Use the Altera tools to generate a couple of example files, and you'll see the format they expect.

    For example, here's a few lines from the start and the end of a MAX II UFM memory contents file: 

    
:020000000000FE
:020001000403F6
:0200020060019B
:020003000400F7
:020004004B802F
:02000500001CDD
:020006000200F6
...
:0201FD00FFFF02
:0201FE00FFFF01
:0201FF00FFFF00
:00000001FF

    You can use the Wikipedia page to 'decode' these bytes. Here's the C-code data to help you decoding the bytes 

    
/* FTDI FT245BM USB-to-Serial with serial number SERIAL01 */
static int usb_to_serial01_data = {
    0x0000, 0x0403, 0x6001, 0x0400, 0x4B80, 0x001C, 0x0200, 0x0A94,
    0x329E, 0x12D0, 0x030A, 0x0046, 0x0054, 0x0044, 0x0049, 0x0332,
    0x0055, 0x0053, 0x0042, 0x0020, 0x003C, 0x002D, 0x003E, 0x0020,
    0x0053, 0x0065, 0x0072, 0x0069, 0x0061, 0x006C, 0x0020, 0x0043,
    0x006F, 0x006E, 0x0076, 0x0065, 0x0072, 0x0074, 0x0065, 0x0072,
    0x0312, 0x0053, 0x0045, 0x0052, 0x0049, 0x0041, 0x004C, 0x0030,
    0x0031, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000,
    0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x896F
};

    Cheers,

    first of all - Thank you very much for your comments and you help.

    secondly- I allready have a GUI software which converts "my language" into MIF file, so for activating a robot by "my language" i have to follow the MIF file .

    i wrote a ROM program (by lpm), and i wrote a program counter which counts up the addresses. but it does not work...

    is some one can guss why ?

    From this comment then, I take it that you understand how to create the MIF file.

    This comment is a little confusing.

    Do you understand how to create a Modelsim simulation? If so, have you created a testbench that reads the ROM and confirms that the bytes are what you expect?

    That would be the first step in confirming that your MIF file has been created correctly.

    Cheers,
