Simulation and Verification

[rrlagic]

Hello,

I am using ISE 13.3 and Modelsim 6.6d as simulator.

I have compiled simulation libraries already, they reside in default location.

When trying to run simulation from ISE environment, Modelsim fails with error

# vsim -do \{do \{tb_ofdm_cnt.fdo\}\}
# ** Error: (vsim-19) Failed to access library 'work' at "work".
# No such file or directory. (errno = ENOENT)
# Error loading design

There is modelsim.ini file in the project directory. There are references to copiled libraries in it. But the real trouble, I guess, is that work library is not created. Even work folder does not get created. I've tried to created that folder manually, but it did not help.

Please advise, how to debug the problem.

Thanks in advance.

Hi.

What happens when you enter

   vlib work

in the project directory?

Do you get error messages?

Does work appear in your modelsim library list?

When the script ends (after the error message) and you enter

  pwd

are you in the correct directory?

Are there spaces or other weird chars in your path?

Have a nice simulation

Hi,

Thanks for spending your time.

There were no weird characters and spaces in path. When launched from ISE, work library did not get created. Somewhere else I seen there was trouble to run modelsim 6.6d from ISE 12.4. I've tried next version, modelsim 6.6e, works for me. Root cause remains unknown to me.

This is a known issue in Modelsim 6.6d/10.0. Please refer to the following answer.

You can reload the .do file in Modelsim.

do xxx.fdo
