Previous Nomenclature
During the process of preparing the SkyWater SKY130 PDK for public release, consistency around naming, documentation and data cross checking was performed. This attempted to make sure that all references have been updated but despite the SkyWater PDK Author's best efforts, some references may have been missed.
This section of the document include information about previous nomenclature around both the SkyWater PDK, related process and technologies developed both by Cypress Technology, SkyWater Technology and their partners.
.. note::
If you find any references to these terms inside the current documentation,
please create an issue so we can update the documentation!
This section should also help people who have previously had access (under NDA) to Cypress and SkyWater PDK files or older documentation and want to migrate to this new open source PDK.
.. warning::
Despite this repository being released under an open source license, you
should **not** publish publically any Cypress or SkyWater IP you have been
given access to under NDA.
If the IP you are looking at includes references to terms found in this
Previous Nomenclature section, it is a good indication that the IP you have
can only be shared under appropriate NDAs and clearances you should **not**
be publically publishing it.
