    symbolic pin in IC6 Reply

     I don't know if this is the right place for my question.

     Recently i begin to use IC6.1, and i need to put a name to some metal lines. In IC5, i used symbolic pin for this, but in cadence 6 i dont know how can do. I try use Netname in metal layer, but when i extract the device, the netname change.

    How can i put a name in a net in layout view? I need know V in this net after simulation.

    Thanks in advance and sorry for my english.

    If you're using a Cadence extraction tool (QRC) and a Cadence LVS tool (e.g. Assura or PVS) you would typically add a pin (geometric pin) at the I/O of your cell - i.e. the pins corresponding to pins on the schematic. You might also have it set up that you can add labels on an appropriate layer to create pins. 

    However, the LVS/extraction process should result in an extracted views where the nets have names corresponding to the matching schematic. 

    SInce this all ought to work, it would probably help if you said what tool you're using for LVS and what you're using for parasitic extraction.

    Thanks,

    Andrew.

    I use DIVA for extract devices and parasitics. I use p-cell and i don't want to do DRC and LVS. For this reason i think i need this:

     how i can do this?

     Thanks
