Graphical PCell support

Naveen002
Naveen002 over 1 year ago

Hi Team,

Recently while trying to work with Graphical Pcell, I got a warning in the CIW (snip below).


This means, after the Graphical Pcell option is removed, the Pcells created by GUI option won't work. Is that the case?
Could you please let us know the impact on this?

Actually we are using GUI PCell option for developing some basic PCells. If it doesn't work after the support is removed, then we feel it's not worth it, developing through graphically.
Please clarify on this.

Thanks,
Naveen Prasad

    Naveen,

    I think I've been advising customers to not use the graphical PCell environment (i.e. Launch→Plugins→PCell) for a good 25 years, and I'd say it's been our general recommendation to not use it. Whilst it's not too bad for simple things, the approach used gets very hard to maintain for anything complex plus they are not very efficient. There has been no significant development of the old graphical tool for many years.

    We've now put a stake in the ground by issuing the message in IC23.1 that this will be removed in future. That doesn't mean that existing graphical PCells will stop working, but the ability to edit them would be removed.

    The recommendation is to use a more modern tool such as Cadence PCell Designer or to use SKILL. Our near roadmap for PCell Designer is to have an import mechanism to import existing graphical PCells into PCell Designer to allow further editing in the more advanced tool (at the moment we have a way of doing this via the general "assimilate" mechanism, but a dedicated import would be better).

    Regards,

    Andrew
