  • OK, I didn't realise you were doing it on a hierarchical component rather than a leaf cell. If you do that, it omits the instance line, but still netlists the underlying schematic as a .subckt - it just wouldn't be referenced.

    If you don't want it to appear at all, what I'd suggest is going to the library manager, and copying the symbol view for the block you wish to ignore to be called "auCdl", and then open the auCdl view for edit, and add a cellView property (Edit->Properties->CellView in the symbol editor) and then adding a boolean property called "lvsIgnore" with value t.

    Then the instance and the definition won't appear.

    Regards,

    Andrew.
