The closed loop testing segment is expected to grow to the highest CAGR during the forecast period. Closed-loop HIL reduces time spent testing fatigue while allowing for a more accurate validation and testing of safety-critical systems. One of the most significant opportunities for growth is in the automotive industry, as closed-loop HIL is critical for validating ADAS, sensor fusion capabilities, and high-voltage powertrain components in realistic processing environments. Additionally, development in digital twin technologies and artificial intelligence has created opportunities to improve the performance and reliability of a product. Strict global safety and functional compliance regulations like ISO 26262 continue to increase the need for closed-loop systems to ensure stringent validation rigor. Meanwhile, modernization in the aerospace and defense sector has created demands for more advanced simulation platforms to facilitate the testing of avionics and unmanned systems in a dynamic, high-risk environment. This creates opportunities for market participants to partner and invest in platforms with scalable, real-time simulation or testing capabilities.

The power electronics segment is expected to grow at the highest CAGR during the forecast period. Power electronics have the advantage of modulating electric current and voltages by controlling the switching cycles of transistors. Power electronic devices are prominently used for electric applications, such as power grids, PV cells, wind turbines, generators, battery energy storage systems, traction motors, electric drives, electric vehicles, and industrial machinery. Hardware in the loop testing helps in testing power electronic devices, such as electric motors and converters, by simulating the load connected to them. This helps with faster and reliable testing of these devices. The electric vehicle (EV) sector offers a significant growth opportunity with the immediate need to test powertrain components, regenerative braking systems, and onboard chargers in the most accurate way possible. The renewable energy sector, particularly solar and wind, also requires advanced HIL platforms to simulate interactions with the grid, energy storage, and control algorithms in smart inverters. Solid-state transformers and wide-bandgap semiconductors (SiC, GaN, etc.) are also emerging as new opportunities that need fast, high-fidelity HIL simulations for optimization and reliability testing. Participants in this market can take advantage of these areas of growth by designing custom HIL systems that are fast, FPGA-based, and can simulate fast, switching transients while integrating control interfaces in real-time. They could work with original equipment manufacturers (OEMs) in the EV sector, renewable energy companies, and power semiconductor vendors to design customized solutions in specific applications. By aligning with and/or developing solutions to address emerging technology applications, vendors will have a reasonable role in the move to a more electrified, efficient, and sustainable future.

The Hardware-in-the-Loop (HIL) market has significant prospects in areas such as electric vehicles (EVs), autonomous systems, renewable energy, and industrial automation. To develop the market's potential, players can build high-performance, real-time HIL systems that meet customer-defined requirements in some key focus areas, including advanced driver-assistance systems (ADAS), power electronics, and smart grids. In addition, participant companies should partner with leaders in the automotive, aerospace, and energy industries and work with them to provide solutions to the next generation of technology. Lastly, the use of artificial intelligence (AI) and digital twin technologies incorporated into HIL frameworks can provide the capability of intelligent, adaptive testing to improve simulation accuracy and efficiency.

In North America, the US is expected to dominate the market during the forecast period. The hardware-in-the-loop (HIL) industry is undergoing tremendous growth in the US due to the rapidly evolving automotive and aerospace sectors, overall electrification, and automation trend. The US has a lot of prominent automotive manufacturers, aerospace companies, and technology innovators that are now using HIL systems to validate embedded systems in real time, save development time, and ensure safety and compliance. As vehicles become more software-based and digital (i.e., advanced driver-assistance systems (ADAS), autonomous vehicles, electric/drivetrain), the ability to test HIL for accuracy, scalability, and efficiency is becoming increasingly important. One of the biggest enablers of growth in HIL is the transition towards electric vehicles (EVs) and autonomous driving. Companies, from traditional manufacturing and tier-1 suppliers to complementary startups, are investing heavily in R&D for EV development. HIL systems serve an increasingly pivotal role in stakeholders validating battery management systems, motor controller systems, and charging systems. The ability to test high-voltage and safety-critical components means that real-time testing via HIL is becoming an increasingly important aspect of the validation cycle. As the trend continues in the aerospace and defense sectors, with both established players and new entrants, HIL simulation is an essential part of the development cycle as reliability and regulatory compliance are critical to complete certification processes.
