Hi Eitan,

Thanks for the reply. I have successfully installed OMNET++ package
on my machine and I am able to run samples available in that package.

But when I tried to run a sample network from the ib_macro_model package,
the run is getting aborted with the following message.

RUNTIME ERROR. A cRuntimeError exception is about to be thrown,
and you requested (by setting debug-on-errors=true in the ini file)
that errors abort execution and break into the debugger.
 - on Linux or Unix-like systems: you should now probably be running the
   simulation under gdb or another debugger. The simulation kernel will now
   raise a SIGABRT signal which will get you into the debugger. If you're not
   running under a debugger, you can still use the core dump for post-mortem
   debugging.
 - on Windows: your should have a just-in-time debugger (such as
   the Visual C++ IDE) enabled. The simulation kernel will now
   cause a debugger interrupt to get you into the debugger -- press
   the [Debug] button in the dialog that comes up.
Once in the debugger, use its "view stack trace" command (in gdb: "bt")
to see the context of the runtime error. See error text below.

<!> Error in module (IBGenerator) FABRIC.H_1.gen: has no parameter
called `GenModel'.
Aborted

Do you have any idea why it is happening ?
