Please provide a source for this claim. Yosys, for example, can't route [1] designs even for Xilinx 7-series devices, and that architecture has been introduced 15 years ago.
[1] Not to be confused with synthesis, mapping, or placing, all of which come earlier in the flow, and for all of which sufficient information is public available.
Yosys doesn't do place-and-route - typically that part would be handled by nextpnr, and there's an experimental fork of that for Xilinx series 7 devices:

It works well enough to build a working litex RISC-V SOC capable of running Linux, for the QMTech Kintex-7 325T board.
I don't think the Cyclone V project has got as far, but I could be wrong. (It kind of slipped off my radar after I realised I was spending way too much time on Discord and purged all but a very few servers to reduce my distractions.)
