In most of the engineering firms that I have worked at, the PCB board was the problem. There would either be a lack of boards due to costs, systems being bulky etc. All these could easily be emulated using Qemu. Is Qemu lacking a good way to model the entire system quickly to start with BSP and application software development? Any help would be appreciated.
