Can't launch the Modelsim-Altera Software after the compilation

I try to re-install Quartus and Models in a different directory and now are both in folder Quartus-Modelsim and the path of simulation assigned is:

C:/Program Files/Quartus-Modelsim/modelsim_ase/win32aloem

but even after the re-installation and the change of directory I have SAME problem.

@kuppe I can launch the Analysis and Synthesis tool and it worked without problem.

I can open Modelsim program without problem but I don't know how lauch a run simulation not started by Quartus. I am a student and I am a very beginner of Quartus but I have to learn to simulate for my exam!

For the log file do you mean this?

possible idea => might be if you have spaces in your project directory

I have this problem for all the projects I try to simulate and they are in differents directory.

this post might help, you might need a \ added to the path

Hello kchan,

Have you run at least the Analysis and Synthesis tool ?

Have you checked the log file ?

Can you run modelsim-altera outside the quartus enviroment ?

If I were you I would change the simulation directory in something like: simulation/modelsim instead of C:\altera\13.1\modelsim_ase\win32aloem

Before open this thread I have already read that post and I already tried but for me that change but don't work.

I solved this problem by putting an extra \ at the end of the path. i.e. C:\altera\13.1\modelsim_ase\win32aloem

Hopefully that is useful to someone.

Problem:

My OS is Windows 7 64 bit. I'm using Quartus II 15.0 Web Edition, and Modelsim 13.1d. I can't launch the Modsim-Altera software after the compilation and the compilation is no error and warning.

I checked Tools>Options>EDA Tool Options:

F:\program file(x86)\15.0\modsim_ase\win32aloem,I can't launch the ModelSim-Altera software. The path to the location of the executables for the ModelSim-Altera software were not specified or the executables were not found at specified path...

I trid to change and add the path:"\" or "/" and cut the modsim_ase files to outside of the program file(x86) files.but don't work.

The way of solving the problem:

The path:"F:\program file(x86)\15.0\modsim_ase\win32aloem" includes a blank space,in other words,program file(x86) contains a blank space or '(' and ')'.You should change the path:for example,

"F:\programfile\15.0\modsim_ase\win32aloem\",

"F:\altera\15.0\modsim_ase\win32aloem\",

"C:\altera\15.0\modsim_ase\win32aloem\"

I try to re-install Quartus and Models in a directory and now are both in folder 15.0 and the path of simulation assigned is:

F:\altera\15.0\modsim_ase\win32aloem\".It does work!!!

note:

1.The install and project directory doesn't have blank space.

2.The default directory path is "C:\altera\15.0".You'd better only change the 'C' to 'F'or other disk.
