Good stories often start over a beer. While sharing a libation or n + 1 with several friends from the industry, one of them mentioned a problem with their fab supplied PDK. Another had a similar problem with a different PDK, by the end next round, I had collected a list of common problems that design groups were having with their PDKs. A process design kit (PDK) models a specific fabrication process for a set of tools used in the design flow blessed by the fab. Using this PDK and following one of the fab supported design flows, the designers can create and verify a design that is manufacturable in that process.
The PDKs available from the fabs not only reflect the specific manufacturing process but can be tailored for markets with the addition of processing steps and devices. This generic PDK works very well for many of the design groups. You can create a design and it can be manufactured. With the competition in some markets, the design groups must take any advantage it can over its competitors. They choose the tools and methodologies specific to their design market and design style, these may deviate from the supported flows. These groups want to enhance the PDK to meet their needs. It isn’t just a drinking problem; these issues are industry wide. An industry wide problem can be solved with a collaboratively developed solution.
In this tutorial, we will explore ways of customizing PDKs to support the tools and devices in your design flow without rewriting the existing PDKs. We will jump in with parameters, resetting defaults and other control and adding new parameters. On to PCells, customize the shapes, connectivity and properties without source code. Add new tools to the flow, integrating the technology and supporting new parameters and models. Integrate your own devices into the PDK and not have them overwritten on an uprev from the fab. These solutions addressed many of the problems seen by the PDK Users. They represent what can be done by working collaboratively to solve common problems yet allowing each user to customize the implementation.
Working together to address common issues, under the anti-trust protections provided by Si2 membership, SIG members create ideas, write white papers, conduct surveys, and develop prototypes; unique solutions sharing a common understanding of the problems.
