Unrecognized function or variable 'vsim'.

i am getting this error i am working with matlab 2020 a and i instaled modelsim student edition and 11.1 with license . can anyone help me ?

[Walter Roberson]

I notice that you mention "student" . If you are using a MATLAB Student license, then you do not have access to the HDL Verifier product that is needed to use vsim .

However, if you are using a MATLAB license provided by your university then that would probably be either a Campas Wide License (new name) or Total Academic Headcount (old name) license, and those licenses are potentially eligible to use HDL Verifier (if the university purchased rights for that.)

[samira sorayaasa]

i have the code verifier license.

[Bharath Venkataraman]

vsim ships with the HDL Verifier product.

Could you please send the output of ver in MATLAB so we can confirm you have HDL Verifier in your installation?

Please also send the output from running "which vsim" on the MATLAB command prompt.

Component:HDLCoder | Category:HDL error

Hello Samira, I use Matlab with Academic Lisence.

Seems Kiran Kintali answer is nonsense and isn't useful.

Could I ask you please, did you find the solution for this issue?

Answer 1

[Kiran Kintali]

Based on your snapshot of ver command above it looks like you do have access to HDL Verifier.

Try using one of the following commands in MATLAB (depending on whether you have Modelsim or Questasim installed on your machine)

>> !modelsim

or

>> !questasim

If you have modelsim or questasim and set them up correctly, they should open.

This is to test whether you have modelsim or questasim, installed correctly, and MATLAB is also seeing the tool.

we do not have your exact error message you were getting here. However, if MATLAB finds modelsim or questasim after doing the above test. The next issue might be because your system environment variables are set in such a way that by default other applications, like MATLAB, or if you run modelsim/questasim from Windows command window, will pick the student version of the modelsim/questasim. Those versions will not work for HDL Verifier cosimulation.

To make sure MATLAB (or any other application in your PC for that matter) to open the licensed version of your modelsim/questasim you must make sure you have set the correct license variable name with right path in your environment variables and make sure the 'Path' has the path to your licensed executable version.

This is expected setup

(Note: blocked out irrelevant paths in black in the snapshot above)

license variable above is MGLS_LICENSE_FIL (your license path might be a path to a license server, my own local license path as you see above). In 'Path' variable you might have path to executable of many applications.

Windows has a priority scheme in reading the ‘Path’ variable, meaning, if you have path to two versions of modelsim or questasim executables in your 'Path' variable definition, Windows will pick one of them.

Hope some of this helps.

Answer 2

[Kiran Kintali]

Possibly install issue. Do you have this file on your path?

>> help vsim
  vsim  Launch ModelSim for use with MATLAB and Simulink.
  
>> which vsim
<path_to_install_root>\matlab\toolbox\edalink\extensions\modelsim\modelsim\vsim.m

[samira sorayaasa]

i dont know i should do this from matlab or from modelsim commands?

[samira sorayaasa]

# invalid command name "vsimmatlab"

this is the error when i want to link modelsim and matlab??

[samira sorayaasa]

i could not find the modsimrand.hdl and midsim_plot.m files ?how can i download them to do tutorial steps?

[samira sorayaasa]

neither help vsim nor which vsim

>> which vsim

'vsim' not found.

please reach out to support for this install question.

[samira sorayaasa]

I sent a request for that

Answer 4

[samira sorayaasa]

i belive the problem is (install package compiler)
