altsyncram simulating issue (single port RAM core)

Hi,

I'm using Altera's core: single port RAM , which includes the component "altsyncram".

when loading modelsim i get the following warning:

Warning: (vsim-3473) Component instance "altsyncram_component : altsyncram" is not bound.

what does it mean and how can i resolve it?

i compiled the relevant altera libraries for simulating( e.g altera_mf library)

Thanks a lot,

Fina.

    Hi,

    I think, the cause could be that you don't compile the altsyncram component.

    so adding "vcom -check_synthesis [your_dir]/altsyncram.vhd' should do it.

    Cheers

    thanks for your answer :-)

    where can i find the file altsyncram.vhd ? it wasn't supplied with the code.

    Thanks,

    Fina.

    When creating the RAM with Megawizard, it should create a *my_ram*.vhd file.

    You need to compile this file. Otherwise, modelsim doesn't know anything about the component you are declaring.

    (sorry for the confusion about altsyncram.vhd)

    Cheers

    thanks for your answer.

    megawizrd did create a *my_ram*.vhd file. but in *my_ram*.vhd file there is an instantiation of the component altsyncram_component : altsyncram .

    seems that the simulator can't find this component. although i compiled the relevant altera libraries (altera_mf etc...).

    Have you put the corresponding library into the modelsim.ini-file?

    insert

    "altera_mf = [your_altera_installation_folder]/modelsim_ae/altera/vhdl/altera_mf"

    into the library section of that file.

    Cheers

    i compiled altera libraries and add the mapping of the compiled folders to library section of modelsim.

    Hi,

    Try putting the *.hex or *.mif files of your ram

    In the modelsim project folder

    This should solve your problem

    Cheers
