These days, an electronic product is much more than the silicon hardware that enables some of its functionality. More products are now driven by sophisticated software—consider the modern car with its 500 million lines of code! With software-defined products, in which operations and enablement of new features are primarily managed through software, verification and validation of these systems is dominating the cost of product development. For these products, digital twins enable a dramatic reduction in cost.
In the technology world, a digital twin is a virtual model or representation of a system under development, providing an efficient way to explore, analyze, and optimize a design before it is finalized. And once the product is out in the field, digital twins allow adjustments or even redesigns based on simulations using real-time data collected from sensors on the product. With a value of $12.9 billion in 2022, the digital twin market is expected to grow at a CAGR of 35% to 40% through 2030, according to industry analysts. This market growth is primarily driven by the increasing adoption of enabling technologies such as AI, enterprise internet of things (IoT) platforms, augmented reality (AR), and virtual reality (VR).

After Apollo 13’s oxygen tank exploded, NASA used multiple simulators to evaluate the incident, extending a physical model of the spacecraft to include electronic components. These days, digital twins are used in an array of industries in addition to aerospace and government, including automotive, healthcare, manufacturing, and construction. Besides physical objects, they can also represent persons or processes. Even Google Maps, serves as an example of a digital twin, in its case of the Earth.
In the semiconductor space, digital twins along with AI and automation, offer the promise of higher quality outcomes along with faster development times. With renewed support of the semiconductor industry through investments such as the U.S. CHIPS and Science Act of 2022, and its counterparts across the globe, anything that can boost productivity in this sector is welcome news.
What Are the Benefits of Digital Twins to the Semiconductor Industry?
According to a of 1,000 companies in segments including life sciences, consumer, energy/utilities, and discrete manufacturing, 80% were employing digital twins. The reasons were varied: new product development, operational efficiency improvements, enhancements to worker safety, and better sustainability.
The , which promotes awareness, adoption, interoperability, and development of digital twin technology, notes that these virtual representations are beneficial because they accelerate a holistic understanding of the product, while enhancing decision-making and effective action. Real-time and historical data allow digital twins to represent the past and present and simulate the future.
Historically, digital twins have largely been used for mechanical parts and components. But as electronic systems continue to feature more complex compute platforms and more software, digital twins have become more common over the last several years. Used at the hardware and software levels, digital twins provide valuable insights that allow designers to examine performance issues, test-drive new features, and optimize different aspects of their product throughout the design and manufacturing processes. They can be applied to virtually any component, from the chip level through sub-systems and all the way up to the system level (like, say, a vehicle).
Silicon chip manufacturers are taking a cue from other manufacturers and using digital twins to accelerate production timelines. For example, , its first AIoT factory leveraging AI and IoT technologies, uses digital twins to simulate process optimization plans and renovation work without disrupting operations. and has made its technology available to other manufacturers.
