@Jonah Saunders - There are some people who have apparently done it -- but it is not anything I have any real insight into. 

A few things to keep in mind:
 * (a) There is **no support** from wafer.space or GF for doing this.
 * (b) It doesn't matter what Cadence reports around DRCs and such, the only thing that matters is what https://platform.wafer.space reports.
 * (c) There is a proprietary PDK for GF180MCU -- if you have an existing NDA (& direct relationship with GF) then you ***might*** be able to get that. wafer.space will *not* provide access to this and you must also see (b) -- (IE It doesn't matter what the proprietary PDK might say, if platform.wafer.space doesn't report it as clean then it isn't clean). GF will also **not** respond to people requesting access to this PDK for wafer.space tape outs.
 * (d) wafer.space does not offer or support waivers.

Generally, if you have the money for a Cadence Virtuoso license, then you probably have money to use a different service which does support those tools. If you are getting a Cadence Virtuoso license for free, then it is likely you don't have the rights to use it for wafer.space tapeouts (if you read the terms and conditions as written).

This makes me wonder about my Intel work computer "personal use policy"

I know virtuoso requires a license

But I've got absolutely no clue what it's details are, and no one has ever told me I need to care or read anything about it
