Declaring global net in schematic composer

RFStuff

 Dear All,

I want to name a net as global so that it can be accessed in the hierarchy.

But also I want the same net should not be created as a PIN in layout.

Could anybody please tell how that can be achieved ?

Kind Regards,

    Not sure why that would cause an LVS error. Which LVS tool are you using?

    It's VLS XL that is creating a pin for any global net- because at the next level up you're going to need to connect to it and so that would be done using a pin rather than an internal net. There's no reason why you can't just delete the pin in VLS XL though, if you really need to. But you may then have issues using VLS XL at the level above because there's nothing to connect to in the lower level block...

    Regards,

    Andrew.
