Porting a design from one technology to another (even the finished layout)

FormerMember

Hello,

I'm looking for help in porting a design from one technology to another (both fairly similar 180nm CMOS) and I already have routines to translate schematics and match up corresponding pCells. However, I'd like to know if the same thing can be done for a layout. Is there any information out there for translating a finished design into a new technology and keeping the connectivity and pCell information for the layout as well as the schematic?

I'd found this post from six years ago but I can't get to the COS solution mentioned and the discussion just sort of peters out.

https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/23001/translating-existing-cells-into-a-different-technology#

Is what I am trying to do not realistic or are there some basic elements that already exist that could help me.

Thanks for the help if anyone has any suggestions.

    Hi Matthew,

    I fixed the broken link to the COS article in that thread, but the article is actually all about schematic migration not layout migration.

    We do have a tool called Virtuoso Layout Migrate which is intended for this purpose, but it's normally only provided under a services engagement because the setup is quite complex and hard to set up; usually the benefit is when you have a lot of similar designs that need migrating as the effort needed to polish the migration can be significant. 

    If you're interested, please contact your account team. Not sure it's necessarily what you're looking for though...

    Regards,

    Andrew.

    Hi Andrew,

    Thanks for the reply. That's the information I was looking for. I had in mind that it was "significant effort" but just wanted to check.

    I'll see if the Layout Migrate is of interest.

    Best regards,

    Matt
