DELRAY BEACH, Fla., 29 April 2025 – The global hardware-in-the-loop (HIL) market is projected to experience significant expansion over the next five years, growing from an estimated US$1.1 billion (£885 million) in 2025 to approximately US$1.78 billion (£1.43 billion) by 2030, according to a new industry report released by MarketsandMarkets. This equates to a robust compound annual growth rate (CAGR) of 10.1% for the forecast period.
HIL simulation is a crucial method for testing and validating embedded systems in real time. It forms an integral part of the development process for complex control systems, particularly in sectors where safety, accuracy, and operational efficiency are paramount. These include automotive, aerospace, defence, energy, and industrial automation. In simple terms, HIL allows engineers to simulate real-world operating conditions for a control system without putting the actual system at risk.
The anticipated growth in the HIL market is being driven by the increasing complexity of electronic control units (ECUs) and a growing reliance on embedded software across various applications. The trend towards electrification in the automotive sector – including the rise of electric vehicles (EVs) and advanced driver-assistance systems (ADAS) – is a key factor fuelling increased demand. According to a report by the International Energy Agency, EV sales exceeded 14 million globally in 2023, and that momentum is expected to continue through the decade.
Automotive manufacturers are investing heavily in simulation technologies to reduce design cycles and improve safety standards. HIL systems allow these companies to test vehicle control systems for braking, steering, and battery management in simulated environments long before a prototype is physically assembled. This leads to faster development times and reduced cost.
The report also highlights the growing adoption of HIL simulation in aerospace and defence. As avionics systems become more interconnected and sophisticated, real-time simulation tools offer engineers a means to evaluate performance and safety without the high cost of full-scale physical testing. According to the European Defence Agency, simulation and modelling technologies are seen as strategic enablers for modern defence capabilities.
North America currently leads the global HIL market, owing to the strong presence of key industry players, including National Instruments, dSPACE GmbH, and OPAL-RT Technologies. However, the Asia-Pacific region is expected to grow at the highest CAGR during the forecast period. This growth is propelled by the manufacturing boom in countries such as China and India, particularly within the automotive and consumer electronics sectors. Rapid digitisation and increased R&D investment in these regions are also contributing to the surge.
The report further notes that the automotive sector is expected to remain the largest end-user of HIL systems through 2030, due in part to stringent regulatory compliance requirements across emissions, safety, and performance. For example, the European Union’s General Safety Regulation, which mandates advanced safety systems in new vehicles from 2024 onwards, is likely to drive more widespread adoption of testing technologies like HIL.
As industries continue to prioritise digital transformation and real-time validation, hardware-in-the-loop is increasingly being viewed not just as a testing tool, but as a strategic component of engineering innovation. The continued evolution of cyber-physical systems, artificial intelligence, and the Internet of Things will only accelerate its importance in the years to come.
