Systemverilog DPI

SystemVerilog

Hi all,

I am looking for a practical example in which systemverilog DPI is connected to Matlab via C Wrapper. Is there any paper published in this field?
I appreciate any suggestion to read about it…

Thanks

Hi Mohammed,

I am an engineer from MathWorks. Although we do not have any specific examples or papers on this topic, there are several ways you can do this, but it depends a little bit on your goal:

If you need full debugging capabilities of both ModelSim/QuestaSim and MATLAB, I would suggest the use of HDL Verifier from MathWorks. This provides a co-simulation link between ModelSim/QuestaSim and MATLAB or Simulink and does not limit your visualization or debug options.

On the other hand, if your goal is different, I would suggest you take a look at a couple of capabilities that allow you to export from MATLAB/Simulink. The above post mentions a couple of these, but just to add/re-iterate you could also:

  • Generate TLM 2.0 models
  • Generate Verilog and VHDL models
  • Generate C/C++ that can be integrated using the DPI

If you are interested in any of these suggestions, let me know. I’d be happy to delve into one further!

Also, I just found an article in the cookbook that has an example you can download.

Hello All,

I ran the example on the socket connection from the following : Matlab/Integration | Verification Academy, but seems could not make the socket connection right from the VSIM client. I am using the QuestaSim 10.1d and Matlab 2012a. From the README.txt, it should work on 10.1/2011a. I got the following errors:

MLerr - connect() failed: Sock Failure ID =111 Connection refused

MATLAB server may not be available, use hdldaemon(‘socket’,5001)

Could the cross network be the problem? Any help is greatly appreciated.

Thanks,
