Yes I totally agree claude can write some damn good firmware! but at an enterprise development team scale for testing needs simulation. It has and always will for any critical embedded system. I think its the other way around that the viability will only get greater. Only this year did people start trusting LLMs with firmware so the bet based on what we saw at industry, the better the AI the better you want the simulation it can use for your development.
The other contributing cause is the actual lack of silicon in supply and we are seeing it especially for the automotive industry, which is only spiking demand for better simulations to unblock teams.
If you want to ship with agents at scale you need a good testing pipeline now more than ever. We don't replace the bench setup test, we look to enhance what you bring to it.
But that doesn't take away from the fact that, yes you could just let your LLM continuously loop on some hardware setup, rinse and repeat for weeks. If you have the hardware and the time to spare.
