Is vivado indirectly required? #82

Open Kreijstal opened 3 weeks ago

Kreijstal commented 3 weeks ago

Since this depends on project x rays, and project x rays depends on an old version of vivado, I guess this project requires vivado, then?

marzoul commented 3 weeks ago

No. Project Xray only uses Vivado to document the bitstream format. Nextpnr only uses the resulting document.

ah, so step 1 of https://github.com/f4pga/prjxray is optional? Or it is for mantainers, not for users, right?

Edit: I actually don't know which steps are meant for users
