Process Design Kit (PDK) Development for particular technology

farhan89

Hello,


I have recently started to develop PDK for our own technology, It is currently in research phase and we do not have much information about technology parameters. My task is to develop PDK. I know there is a FreePDK available that I could use as a base PDK. But, I am planning to start everything from scratch (because it is not CMOS technology). I have already written the basic technology file (*.tf) using DEFT and also the display.drf. Now I am moving towards pCell development. I have some experience with CAD tools and programming (C,perl, SKILL). My question is how hard would it be to make a develop whole PDK flow (Schematic, layout, simulation, DRC, LVS, extraction) for our own technology.

Secondly, I have heard about this Open-Acess PDK's but haven't worked with them. Should I focus open-access based PDK development ?.  After developing whole PDK would it be difficult to convert it to open-access based PDK?.  Any good guides related to Open-Access PDK development

Thanks

    Given that the last non-Open Access Cadence release was IC5141, which was released in 2004, had the last hotfix in November 2011 and had the final end-of-all-support date at the end of 2015, there is absolutely no good reason to create a non-Open Access PDK. It's a waste of time. There have been 8 major Open Access-based IC releases since then (plus three advanced node variant releases).

    Here's a useful document on developing PDKs for OA.

    Regards,

    Andrew.

    Thank you Andrew for the explanation regarding OpenAccess. I have tried to access the document via the link you have given, when I entered the host key it gives me error that host key not found in the system.

    Is it because we are academic institute and we got the license from Euro Practice ?

    Hi Farhan,

    As part of the EuroPractice scheme you should be able to access to support.cadence.com (not for submitting cases to support, but for reading the material there). I suggest you contact one of the contacts on the EMEA section of this page:

     

    The benefits certainly say you can access support.cadence.com; I just don't know the mechanism for registering an account for an academic institution.

    Regards,

    Andrew.
