by LT Clark · 2016 · Cited by 281 — We describe a 7-nm predictive
process design kit (PDK)
called the ASAP7 PDK, developed in collaboration with ARM Ltd. for
academic use. The PDK is ...

it claims to be a Foundry-agnostic PDK.

in practical terms that means it's not an actual Foundry PDK, it will be
more like something that can be run through DRC checking and etc.
etc. but no Foundry *actually* can take the GDS-II Files and create
actual silicon.

to create an ASIC you need a *Foundry* PDK for the specific node.
skywater was more than happy to release their 130 nm PDK: they are
the only one so far.
