MATLAB: Do I receive an error when I run the SETUPMODELSIM command to link a ModelSim installation with Simulink on Linux

EDA Simulator Link MQerrorforinstalllinklinuxmodelsimsupport

The following question appeared at the prompt when I executed the SETUPMODELSIM command to link a ModelSim installation with Simulink on Linux:

 Do you want setupmodelsim to locate installed ModelSim executables [y]/n?

I received the following error when I pressed 'y'

 ??? Error using ==> setupmodelsim                                          
 This platform is not supported by Link for ModelSim

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in Link for ModelSim 1.1.1 (R14) in the way that it handles the SETUPMODELSIM command.

Currently, to work around this issue, try the following:

1. Press 'n' when prompted by the following question:

 Do you want setupmodelsim to locate installed ModelSim executables [y]/n?

2. Enter the path to the ModelSim executable (e.g. /Applications/Modelsim58seinstaller/modeltech/linux/ ) when prompted by the following question:

 Please enter the path to your ModelSim executable file (modelsim.exe or vsim.exe):

3. Press 'y' when prompted by the following question:

 Previous MATLAB startup file found in this installation of ModelSim:
 /Applications/Modelsim58seinstaller/modeltech/linux/../tcl/ModelSimTclFunction
 sForMATLAB.tcl                                                             
 Do you want to replace this file [y]/n?

MATLAB: How to setup Link for ModelSim to work off a network installation of ModelSim

SETUPMODELSIM is strictly a convenience and is not required to use Link for ModelSim. The basic requirement is to start ModelSim by using the VSIM command in MATLAB. SETUPMODELSIM alters the ModelSim installation, so you must have write permission to the ModelSim installation files to use SETUPMODELSIM.

Details:

ModelSim must be configured to work with Link for ModelSim. For example, the Link for ModelSim commands MATLABTB, MATLABTBEVAL, etc., must be registered with ModelSim. If ModelSim is not configured, you will not have access to these commands.

This configuration can be performed in two ways.

1) When you start ModelSim from within MATLAB using the VSIM command, the VSIM command configures that invocation of ModelSim.

2) Running SETUPMODELSIM alters the ModelSim installation so that every invocation of ModelSim will be configured regardless of how you start ModelSim. You no longer have to use MATLAB VSIM to configure ModelSim. If you do use MATLAB VSIM to start ModelSim, the parameters you specify with VSIM override the default configuration created by SETUPMODELSIM.

If MATLAB and ModelSim are not installed on the same system, use the following steps to configure ModelSim:

1. Identify a valid and available socket port on the system that is running ModelSim.

2. Execute the VSIM command in MATLAB with the 'startupfile' option to generate a DO file for ModelSim and the 'StartGUI' option set to 'no', e.g.:

vsim('startupfile','filename.do','StartGUI','no','socketsimulink','tcp_spec');

where 'tcp_spec' specifies a socket port, a TCP/IP socket port number, or service name identified in step 1. For more information about the VSIM command, type

doc vsim

at the MATLAB command prompt.

3. Start ModelSim with the generated DO file by using the VSIM command at the operating system command prompt:

vsim -do filename.do

4. Now call VSIMULINK from ModelSim. Note that this will generate an error because MATLAB and ModelSim are not installed on the same system:

 # Loading D:/Applications/MATLABR14SP2/toolbox/modelsim/win32/simulinklink.dll 
 # ** Error: (vsim-3193) Load of "D:/Applications/MATLABR14SP2/toolbox/modelsim/win32/simulinklink.dll" failed: File not found. 
 # ** Error: (vsim-FLI-3160) Failed to load FLI object file "D:/Applications/MATLABR14SP2/toolbox/modelsim/win32/simulinklink.dll".

You must copy the simulinklink.dll file from the host computer to the computer where ModelSim is installed and recreate the same directory tree or change the DO file manually.

MATLAB: How to pass TCL commands directly to ModelSim from MATLAB using Link for ModelSim 1.4 (R14SP3)

This functionality is available but undocumented in Link for ModelSim 1.4 (R14SP3).

To work around the issue, read the description below on how to use an undocumented option for the HDLDAEMON command. The 'TCLCMD' option will send a TCL command from MATLAB to be executed in ModelSim. This interface has some limitations; using it to send TCL commands that changes the state of the simulator is not recommended and can cause hang-ups. This is a limitation of ModelSim and is documented in their interface.

To send a TCL command from MATLAB to an open ModelSim session, you must first connect to ModelSim using the HLDDAEMON command. You will then be able to use the undocumented 'TCLCMD' option for the HLDDAEMON command, which will pass commands to ModelSim. For example, typing the following command at the MATLAB prompt:

hdldaemon('TCLCMD','echo "Hello"');

This code will display the word "Hello" in the ModelSim prompt. To quit any connected ModelSim sessions, you can use the following command:

hdldaemon('TCLCMD','quit -f')
