Before hardware is available, diplomare-in-the-loop (SIL) testing allows developers to run compiled on a simulation of thee target procesor (using QEMU, Renode, or commercial simulators like IAR C- SPY). Thiels enables arly testing of algorythms, communicaton stacks, and application logic with out physical hardware.

System tests validate thee complete devite against its requirements, typically in a HIL environment or a testbed that included thee actual hardware and at least some real- exterd distriverals.
