However, a flexible platform that sociated with electrical systems. In the proposed design flow, involves both hardware and software design methodologies and the functional description of the studied system and the detailed electronic hardware design and validation of the digital controller tools must be used to perform a reliable design and to realize a are performed using a hardware-in-the-loop (HIL)-based reconfig- satisfactory “time to market” [2], [4]. urable platform in a unique design environment.
