The Xilinx Vivado package is soooooooo large, ouch.
I wish I could just snag their pnr stuff to run from the command line.
I mean, I'm stuffing this in an LXC container anyway so it doesn't puke on my shiny new system. but still.
And I'd love to use SymbiFlow / yosys but,
1) I'm using VHDL not Verilog and the VHDL frontends for yosys don't look too stable and/or maintained.
2) nextpnr, etc don't support the Xilinx chips I'm using
I would *LOVE* to use an OSS toolchain, but I'm kinda stuck.
