How to add path to Modelsim to correct "the design unit was not found"?

--- Quote Start ---

Error: (vsim-3033) ./submodules/q_sys_altmemddr_0_phy_alt_mem_phy.v(2925): Instantiation of 'cycloneiii_io_obuf' failed. The design unit was not found.

How to add the path so that Modelsim can find the cycloneiii_io_obuf

That sounds like a Cyclone III low-level component. Usually those types of things are in quartus/eda/sim_lib/cycloneiii_atoms.v, which is pre-compiled for Modelsim-ASE. However, I just searched the sim_lib/ folder and could not find that component (11.1sp1 installation).

If you can find where that component is located, then you can add the folder with the vlog +incdir+ option (see vlog -help).

Cheers,

Thank you, I can see the component is listed in the Library window of Modelsim (as shown in attached pic).

But Modelsim seems can not find it to compile.

I found it in my (11.1Sp2.dp8) cycloneiii_atoms.v model

I just rechecked, and I do find it in the 11.1sp1 files too. I must have mistyped something :)

binpersonal: on the Modelsim command line, type 'vmap cycloneiii_ver' and see if the library is mapped correctly. If not, you've messed up your Modelsim library mappings. In that case, I'll try to help you fix it.

Dave,

I have faced this problem, but i have no idea to fix this problem. Would you like to help me to fix. thanks

Hi jame.song,

Can you post a small code example that shows the error?

Or post the error message output by Modelsim.

Do you know that your setup is correct?

For example, run one of the simple Modelsim examples I've posted, eg.,

http://www.alteraforum.com/forum/showthread.php?t=32386

or this one

http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial

(the first is VHDL, the second is Verilog/SystemVerilog, so may be more applicable to testing your setup)

Cheers,

Dave
