Considering to make nextpnr-ice40 the default P&R tool for the FuseSoC icestorm backend. Any reasons for keeping arachne-pnr default other than not forcing people to install a new tool? Are there any features still missing from nextpnr?

Good to know. I have spent much of the day trying to figure out why arachne-pnr doesn't read some yosys blif files. (seems like read_json ; write_blif creates .subckt cells that arachne-pnr seemingly doesn't handle)

I suspected something like that. Looks like a good opportunity to dig into yosys commands again
