What bothers me, is that all the Digital Design tools are freaking expensive and closed source. For example, building RISC-V is possible on FPGA board, but you have to have Xilinx tools (or some other brand).
Both Xilinx and Altera^H^H^H^H^H^HIntel provides gratis tools for their lower end FPGAs, but those are plenty to implement an SoC, even one that can boot Linux. In particular Cyclone V A9 is a pretty impressive FPGA. Sadly, Intel decided to _not_ provide gratis support for their Cyclone 10 GX :(
