Embedded software, unlike general software, is highly dependent on the hardware they are developed for. Thus it became essential to create a hardware-based or hardware-like environment simultaneously with the software for effective testing. Where simulators and emulators can, up to some extent, provide a hardware-like environment for testing embedded software, they can not always be relied upon while testing for safety-critical applications like flight control system. It is this, high dependency on hardware, which makes testing, verification, and validation of embedded Softwares far more demanding than of general software. Moreover, several safety-critical embedded systems are also strictly real-time, or at…
