that's really cool idea, but for such r&d local hardware/vm seems to be more ergonomic for attaching debugger and if you have to create such abstractions anyway

that's really cool idea, but for such r&d local hardware/vm seems to be more ergonomic for attaching debugger and if you have to create such abstractions anyways, I'm not sure if dev board with second CPU or FPGA for hw emulation wouldn't be better way to handle it, as this would allow you to reuse same boats between generations
