Edit Pin Name and Width

cgurleyuk

Hello,
I want to create a new schematic from the library which is created by me. I put an instance from this library to the new schematic. I want to change pin names of this instance. The problem is that some pin names have a bus notation ( Ex: A<3:0>) and i want to change width of this pin (Ex: A<5:0>). Cadence document says width of pin cannot change by " myInst~>pin~>term~>numBits". Is there any way to do this?

Regards

    You can't change the name of the pin on an instance - it makes no sense. This is nothing to do with it being a bus pin - but the pin name (or rather terminal name,) can only be set on the master (i..e the symbol itself). This then has to match the corresponding schematic, otherwise view switching during netlisting won't work.

    So I'm not sure what you're really trying to do here?

    Regards,

    Andrew.
