Merge activities with upstream #26

Open unbtorsten opened 2 years ago

unbtorsten commented 2 years ago

This issue is a reminder to regularly review code and

push tested code to upstream projects where possible.
separate i) system requirements (readily available from upstream), ii) customization of upstream tools (make setup), and iii) minimum working examples (e.g. make blinky) whenever possible

@hansfbaier, @jrrk2, @rwhitby et al.

After talking with @mithro, I advocate for merging the activity in this organization and its repositories entirely with F4PGA (formerly 'SymbiFlow'), cf. https://github.com/f4pga/f4pga. In fact, this is where I will place my focus as we are moving forward.

I believe that the code of this repo has its place in https://github.com/chipsalliance/f4pga-examples, anything related to setting up tools has a place in https://github.com/chipsalliance/f4pga-docs. Discussions of all sorts of related aspects take place in #f4pga's slack channel at https://slack-invite.chipsalliance.org/

I'm ok with that, but the slack link didn't work for me - it asks for a workspace URL.

f4pga-example seem to be f4pga toolchain only. Do they accept nextpnr-xilinx examples?

Wouldn't that go directly to https://github.com/gatecat/nextpnr-xilinx/tree/xilinx-upstream/xilinx/examples ? Either way, @gatecat may be able to answer that question for you.

That doesn't seem to be a publicly accessible server? Is an invite required?

Sorry about that.. yes, here is the link: https://slack-invite.chipsalliance.org/

It makes sense to not duplicate effort, however the F4FPGA(Symbiflow) flow has a lot more steps in it than the nextpnr flow, starting from the same prjxray-db database. The conversion to symbiflow doesn't actually work for Kintex7 at the moment, possibly because the prjxray-db is incomplete.
