That's why nextpnr exists :)

As someone actively working on nextpnr support for a fairly new FPGA architecture, it really is amazing that we have something like that in the open source world.

YosysHQ are one of my favorite companies to exist.

Nextpnr and Project X-Ray are amazing projects. Reverse engineering the physical map of, say, a 7-series FPGA is no small feat. However, I wonder if they'll ever be able to really compete with Vivado without getting access to the characterization models for timing. I would love to switch over, but the Fmax of my project routed with nextpnr is less than half of what I get with Vivado.
