According to the Market Statsville Group (MSG), the Global Hardware-in-loop Testing Market size is expected to grow from USD 835.22 million in 2022 to USD 2,177.08 million by 2033, at a CAGR of 9.1% from 2023 to 2033. Vehicle modernization with advanced features such as Advanced Driver-Assistance Systems (ADAS), cameras, and radar increases the complexity of embedded control systems. Furthermore, the complexity is increased when one electronic control unit (ECU) in a vehicle equates to a massive number of signals representing various functions and I/O types.
