Is it okay to design with Cadence software and still submit on the MPW runs? If the gds files are published open source?

The "design" needs to be open source which would include design inputs: verilog, netlist, schematic, etc.

So if I post all of these as an OA database from cadence is that fine?

I doubt it. OA requires NDAs to get access

Despite being "Open" Access, it is not very open

<@U018ZPCLWUA> Convert your OA to EDIF for schematics and publish it.

Adding to this the GDS, netlist files and all the other stuff

<@U0175T39732> BTW OA is an open standard and own by any company. But I know that Cadence was driving it’s development and it has it’s own constructs.

<@U01EK2VDMDG> OpenAccess is open like in Open UNIX. I was advized to not sign the agreement to get access to the OpenAccess reference implementation as it would forbid use of the code in open source software.

<@U0177MGKM7A> I didn't read the license in details to be honest here. But thanks for the highlight.
