Troubleshooting IFV

JASK

 Hi,

    I am new to IFV. I was trying to run the tutorial example (given in ifvtut1 in the docs), but I am facing some errors even at that point.

cd examples/ifv

ifv -f fifo_cntl.f +gui

IFV seems to compile the .vhdl file properly, and is about to launch the GUI window, when an error appears. 

formalverifier: *E,STRPIN:Could not initialize SimVision connection: SimVision process terminated before a connection was established. 

 

When I try without the +gui option too, it gives me an error.

formalverifier: *E,URSYST: Unrecognized system task (did not match built-in or user-defined names) $get_simulationscratch.

 

Has anyone come across this before? I would really appreciate any help in fixing this.

PS: It's a university tool. Could it be an installation bug?

  • Jayanand

    Can you share the platform and version of OS you are running on?  I want to make sure you are running on a supported OS first.

    You can also run "ifv_check".  This utility will check to ensure you are on a supported platform.  You are looking for an overall Pass from this untility.

     Regards,

  • I quickly confirmed that the tutorial runs fine for me.  Let's see the report from ifv_check.

    It would be helpful if you include what version you are using.

    Although it has been fixed in the latest releases, there was a problem if you got your IFV and IUS installation paths mixed. This would happen if you have your IUS path first. What happens is that you call IFV (that doesn’t exist in the IUS release) and so it gets the IFV executable from the IFV release directory. But then you call SimVision that does exist in the IUS release and so it gets a different version from the IUS release directory.

  •  Tim and Jose: Thanks for the prompt response.

    I am running the tool on a Red Hat Linux system (version 5.2 I think).

    IFV and IUS are both version 6.1. I am copy-pasting the log file from ifv_check (see below). It looks like the IUS path is taking precedence for launching SimVision as Tim suggested.

     Could you guys take a look and confirm this?

     

    Thanks,

    Jayanand

  • Jayanand

     The answer is in the output you appended.  As you can see the IUS path is first.  You need to put the IFV path first or have it be the only tool in your path.  Once you correct this, run ifv_check again to ensure your system is supported.  I believe IFV 6.1 was not supported on Redhat 5.  You will need to find a Redhat 3 or 4 system to run on.  If you can, upgrade to IFV 8.1 (same for IUS 8.1) as this version will run on Redhat 4 and 5.

    Hope this helps

    Jose

  • Our tech guys used the info you provided here and corrected the path ordering . Now the tutorial works fine for me. The OS being Redhat 5 is not causing any trouble as of now. 

     Thanks a lot for your help.
