The GP mentioned 'tooling and expression', I mentioned tooling, you're mentioning expression. Aside from that, other HDLs than just Verilog and VHDL do exist, such as Chisel and CλaSH: https://chisel.eecs.berkeley.edu/ https://chisel.eecs.berkeley.edu/ http://www.clash-lang.org/ http://www.clash-lang.org/ Also, whilst I'm sure open source EDA tools could be improved, some of the basic building blocks exist, it appears to be more of an issue of packaging than availability. Seems like EDA tooling is a niche that a specialist Linux distro could fill (if tutorials are also provided).
