To be clear, creating a linux capable Artix-7 image using only open source tools can be done today, right now! https://github.com/SymbiFlow/symbiflow-examples

Awesome! Hadn't seen that, includes the DDR controller too which I thought may be one of the trickier parts to get going under Symbiflow.

Eh, did they finally unlock all the transceivers, MMCMs, DSP48s, etc?

It's super unimpressive to do a basic processor with flip flops and BRAM with a primitive simulated-annealing P&R. You're getting like... 10% of what the chip from a decade ago was capable of.

Eh. I guess. If your time is worth zero and you're willing to overpay for silicon you can't use effectively with your open tools. Webpack is gratis from Xilinx and it stomps the open source stuff, I have no idea why you'd bother.
