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?

    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.
