Modelsim can not find "altsyncram"

[Altera_Forum]

Dear all, I am using Modelsim for simulation, 

 Modelsim says" Instantiation of 'altsyncram' failed, the design unit was not found", even though 'altsyncram' is in "Altera_mf" library, listed on the "library Panel".   What should I do?  Thank you very much!  Other errors: "Instantiation of 'oper_selector' failed, the design unit was not found", there is a .ocp file in altmemphy-library, what does it do? should it be included in Modelsim?

Seeing the library in the library panel does not mean that they are included.  Kind regards  GPK

Could you tell me how to include? how to check?

# get a proper makefile 

exec vmake work > Makefile # Run it to compile what needs to be compiled make # Start simulation vsim -L altera_mf_ver -L lpm_ver -L cycloneiii_ver -L cycloneii_ver work.dut_tb    After those you can simply do: make; restart -f; run -all

I also met this problem.  

 I am using modelsim in a Ubuntu 10.04 LTS Lucid Lynx. Also i am compiling verilog files (and simulating them) in command line.  I fixed it using the following command (after all necessary compilations):  vsim -c -t 1ns -quiet -L $(MEGAFUNCTIONS) work.RomTests -do "run 1000000 1ns; quit"  where MEGAFUNCTIONS should be your path to "altera_mf", which includes all megafunctions from altera: [installation path]/altera10.0/modelsim_ae/altera/verilog/altera_mf

Compile the testbench code <testbench.v> , it gets included in your 'work' library. 2. Select 'Simulate' -> 'Start Simulation' from the menu. 3. Click on the 'Libraries' tab in the new popup window and press 'Add' to include the 'altera_mf_ver' library (if you are working with Verilog) to the 'Search Libraries First (-Lf)' 4. Finally, select your testbench from the 'Design' tab.  The design should simulate now.  I have included some screenshots for assistance.

Many thanks for the explanation listed as the 4 steps above. I am new to Modelsim-Altera and this solved the problem. I am now simulating my memory successfully, however I got caught out because I registered both the address and q without realising. Simulation and google(!) helped me find the bug.
