That is correct. We have FPGAs, qemu, and formal models (that can boot an OS) of CHERI-RISC-V and CHERI-MIPS. Most software development uses qemu as it is faster than the FPGAs at around 100MHz.
Having something in the GHz range will give us a chance to try things we are currently struggling with, e.g. fuzzing is painfully slow.
