As silicon integration technology advances and clock frequencies increase, optimizing power and reaching high performances has become crucial in developing Embedded Systems and Systems on Chip (SoC). Field-Programmable Gate Arrays (FPGAs) are semiconductors that offer high flexibility as they can be reprogrammed after manufacturing, offering lower design cost and customization for specific applications. However, this flexibility comes at a price - FPGAs are less performance and energy efficient. Therefore, to achieve significant performance improvements, it is necessary to rely on architectural modifications and technology scaling of digital designs to operate beyond conventional safety limits. Typically, FPGA systems provide large timing guard bands during the design phase to guarantee safe operation across manufacturing and design.
