Do you only get a choice to run one of the four then? That makes sense to put two comparisons on the same 'test" die, a lower end comparison and a higher level comparison. -- Rick C. -- Get 1,000 miles of free Supercharging -- Tesla referral code - https://ts.la/richard11209

I don't know if you can mix and match with one ARM and the other RISC-V, or if both have to be from the same vendor.
