I would love to hack on FPGAs but always run into the issue of closed toolchains. The recent open source work is a breath of fresh air, but we need to see an FPGA vender that embraces and sponsors this work.
Lattice is seemingly at "wink wink, nudge nudge" levels of support -- their lawyers won't allow them to say anything because they're afraid of pissing off Synopsys, but they also know that they're currently the best supported platform, and don't seem interested in deliberately making things difficult.
I would like to see a FAANG try and support some open tools - it doesn't have to be anything legally sketchy like reverse engineering bitstreams - for example, Yosys only has limited SystemVerilog support
At some point I'd like to see it integrated as the frontend to tools like Yosys to get best-in-class SystemVerilog support in open tools.
