puzzle about the session defination

imagesensor123

Hi all,

    i saw in the artsit skill guide, there are several "session". ususally, we can use the sevSession(O_entry) to get a simulation environment session, the return value is "session", and many times, i saw the required data type is "o_session", is it the same thing? could you please give some introduction abou the "session" , and what's the session indeed.

 

  • Because you can have multiple ADE sessions, many of the functions require something to tell it which session you're talking about.

    The simulation environment ("sev") needs to know which simulation environment you're talking about, so that's a "sevSession". The underlying OASIS layer (which is the Analog Simulation Interface, "asi") requires the asi session. A sevSession is actually just a symbol, and a asi session is an instance of a class. Typically the sev functions expect a sev session (such as sevSession(hiGetCurrentWindow()) and the asi functions expect an asi session (such as asiGetCurrentSession()). There are some functions like sevEnvironment(sevSessionId) which will return the asi session corresponding to the sev session. 

    It's all about which layer in the system you're dealing with. For example, OCEAN is all built on top of the "asi" layer - there is no simulation environment (sev) at all - because there's no UI.

    That was probably as clear as mud ;-)

    Regards,

    Andrew.
