Two Pins on the one wire

MatthewLove

Is there a way to place two pins on a wire without creating a short?

I'm trying to make a four port transformer PCell.

Each winding is just a metal path and I can't see how to have input and output pins for each path without causing a short.

In a previous project I used metal resistors to break up the wires but that was time consuming and wouldn't be process independent.

    Hi Matthew,

    maybe you'll find that useful.

    Kind regards,

    Matthias

    Is this a schematic or a layout pcell? If it's a layout pcell, presumably it's not entirely technology independent anyway - and the way to break the connectivity for LVS would depend on how the LVS tool and rule deck (whatever you're using) deals with this.

    Hi Andrew,

    Well, it's just two coils of metal for now and the layers can be supplied with strings as parameters.

    I'll just stick to the workarounds for now then if this isn't simply done.

    Thanks.

    This looks pretty useful though I still need other components otherwise calibre will complain that my layout has no schematic components.

    Looks like I need to use the metal resistors regardless.

    Thanks for the reply.
