exiting an ocean session in the CIW

markbeck

I'm trying to create an external netlist with a skill script and the only way that I know how to do this is to issue the following commands:

simulator('spectre)
design(t_lib t_cell t_view)
netlistDir("/some/directory/path")
createNetlist()

This works fine, but if I don't issue the run() command, the CIW thinks that I'm still in an ocean session. I can't issue an exit() command because the CIW interprents this as "exit virtuoso".  

Does anyone out there know how to exit an interactive ocean session in the CIW without issuing a 'run()' command?

Thanks,
Mark

  • Hi Mark,

    I have not tried this out, but it looks promising from the function name and documentation: ocnCloseSession()

    ocnCloseSession( )
         => t / nil


    Closes the current OCEAN session without saving any settings made during the session. The command has no effect if no session is currently active.

    The "simulator()" command starts the simulator session, so I hope this function closes it.

    Hope it helps!

  • That's exactly what I was looking for.  (sigh... need to learn how to search the documentation better...)

    Thanks,

  •  Ok, I now know why I didn't find it.  I was searching in the 5.141 documentation.  That is a new ocean function.

    Is there a way to do this in 5.10.41?

  • Hi Mark,

    I'm not sure for IC5141, running "simulator()" again would close the current session, but it would start a new session, so I'm not sure if that meets your requirements?

    Hope it helps.

    Regards,
    Lawrence.

  • Mark,

    The only way to do this (that I know of) in IC5141 is to use a private SKILL function. Actually just discovered that even the private way breaks things, so I definitely won't be suggesting that! Why do you need to close the OCEAN session? It shouldn't cause any problems for running things in IC5141 if the session is still active.

  • The main reason that I want to end the session is that I was seeing the ADE-L license being held long after the netlist was written out.  The 'nicest' way to release it is to end the ocean session.  But the other way, would be to release the ADE-L license with the lmCheckIn() command.

  •  Mark,

    I guessed that might be the reason. Unfortunately there doesn't seem to be a way to destroy the OCEAN session in IC5141; when I tried it, I found that I couldn't run any more OCEAN sessions unless I quit icfb/ocean. That's why the new function was added in IC61.

    Regards,

    Andrew.
