    Updating the Symbol Pins while doing schematic PIN change Reply

     Dear All,

    I I ahve already created a symbol for the schematic. 

    But now I modify some pins in Schematic but I am not observing same modifications being propagated to its corresponding symbol.

    Is there any way to achieve the same.

    Kind Regards,

    It doesn't happen automatically. You can use Create->CellView->From CellView to create the symbol again - you can pick "Modify" rather than "Replace" and then it will delete any pins from the symbol which are no longer present, and then add the new pins at the bottom (with a note telling you it did this) - if you've chosen to "Edit" the resulting symbol you can clean it up afterwards - of course, it doesn't know where it is safe to add the new pins, so it leaves that to you to decide.

    Regards,

    Andrew.

     Dear Andrew,

    Thanks a lot for your reply.

    Couple of doubts:-

    1)

    If composer finds one to one realtionship between the symbol pins and the pins in schematic, then I think one can exploit this relationship. What I mean is:- Suppose there is a PIN A in schematic and corresponding one in Symbol. If I rename PIN A to B,then through the above relationship the corresponding PIN in symbol should change to B. Of course adding a NEW pin is totally a different story.

    2)

    I think if I have modified the original created symbol by composer ( it is generally a square/rectangle) to a suitable circuit looking symbol let's say for example a OPAMP symbol for a OPAMP circuit, then Create -> CellView-.... method will change the shape from OPAMP to a rectangle which I don't want.

    Kind Regards,

    1. In theory it could, but it doesn't
    2. The "Modify" mode doesn't change the shape - it leaves the existing symbol graphics as is, and only adjusts the pins.
