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).
