Hello

I am using simulation waveform editor (Altera Quartus II 64-Bit 14.0 Web Edition) to simulate a simple RS latch with verilog as follows.

---------------------------------------------------
module rs_latch (Clk, R, S, Q);
input Clk, R, S;
output Q;

wire R_g, S_g, Qa, Qb;

and(R_g, R, Clk);
and(S_g, S, Clk);
nor(Qa, R_g, Qb);
nor(Qb, S_g, Qa);

assign Q = Qa;
endmodule
---------------------------------------------------

The input setup of RS latch simulation in simulation waveform editor is as attachment.
And when I use "Run Functional Simulation" or "Run Timing Simulation", it would start to run a series processes, and I would get a error message as follows.
(only list part of error message because of the characters number limitation in this forum.)

Determining the location of the ModelSim executable...

Using: C:\altera\14.0\modelsim_ase\win32aloem

To specify a ModelSim executable directory, select: Tools -> Options -> EDA Tool Options
Note: if both ModelSim-Altera and ModelSim executables are available, ModelSim-Altera will be used.

Error.
--------------------------------------------------------------------------------------------

By the message, I think when it links to the library, it can not search the correct library path.
I know it links to the library by the "modelsim.ini" in the path "C:\altera\14.0\modelsim_ase\", and part content of "modelsim.ini" is as follows.

----------------------------------------------------------------
altera_mf = $MODEL_TECH/../altera/vhdl/altera_mf
altera = $MODEL_TECH/../altera/vhdl/altera
altera_lnsim = $MODEL_TECH/../altera/vhdl/altera_lnsim
lpm = $MODEL_TECH/../altera/vhdl/220model
220model = $MODEL_TECH/../altera/vhdl/220model
maxii = $MODEL_TECH/../altera/vhdl/maxii
maxv = $MODEL_TECH/../altera/vhdl/maxv
fiftyfivenm = $MODEL_TECH/../altera/vhdl/fiftyfivenm
...................

----------------------------------------------------------------

I have tried all possible setting about the library path, but I still can't solve this problem.
Can someone help me to solve this problem or tell me how can I correctly link simulator to the library path?
Or did I miss some important steps here?
Look forwarding to your help.
Thank you very much!!!!

Hmmm.. the libraries in The Altera edition of Modelsim should have pre-compiled libraries.

In your project, verify Assignment->Settings->EDA Tool Settings->Simulation->Tool Name = ModelSim-Altera

Also verify the path at Tools->Options->EDA Tool Options->ModelSim-Altera  points to the correct path to the winXX binaries.
