Why do I need to draw the same symbol N times?

autodeskguest

More often than not the same chip is available in different packages,

quite often with different number of pins and the packages with fewer

pins omit some of the lesser used signals.

 

Currently, you need to create a different symbol for every package: if

you have a chip that comes in 5 different packages, with a few pin

differences, you need a symbol drawn for ABC1234-SOIC, ABC1234-BGA,

ABC1234-TSOP and so on. It's the same damn chip, just on some packages

some pins are missing.

 

I wonder if I'm alone with the wish of having just one symbol, with

every possible signal drawn. Then, when it gets placed to the schematic

with a package selected, the not bonded pins grey out and don't allow

wires to be connected to them?

    It would help if the Table of Contents view of the library allowed copying

    a symbol, so that you can draw the most extensive symbol for the component,

    copy it, delete some pins from the copy (repeat for all variants).

     

    The way I work around this is by drawing the symbol, saving the library and

    exiting the library editor, then opening the library in a plain text

    editor, find the symbol you just added, then copy/paste it (between <symbol

    name="..."> and </symbol name>), with a modified name for the copied

    symbol. Then reopen the library editor, edit the copied symbol and delete

    the pins not used in that variant.

     

    Why don't you simply use GROUP - CUT - PASTE within the symbol editor?
