You could do this with an emulator I&#x27;m sure. At my company we have fairly high-fidelity models of the hardware we use&#x2F;develop which could probably include on-chip peripherals in the things fuzzed. Also I guess in irradiated environments you use very simple hardware (no caches, MMUs, complex memory bus&#x2F;controller) so that would make it more feasible. Would probably be really fun to develop!<p>Edit: if you had the resources maybe you could even fuzz simulations of the RTL. Our systems take about a week to boot Linux on simulations but I guess that would drop dramatically for simpler MCU systems.
