X-Epic, a prominent Chinese electronic design automation (EDA) start-up, is said to be reducing its workforce by up to 50%, according to a report by South China Morning Post. As chip design is an indispensable part to semiconductor manufacturing, the incident raises concerns about China’s push for technological self-reliance.

X-Epic, founded in 2020 by Wang Libin, a former engineer at US EDA leader Cadence Design Systems, has been established with the goal of creating indigenous EDA tools to challenge the dominance of US rivals. The field is traditionally governed by US giants including Cadence, Synopsys, and Mentor Graphics (now owned by Siemens).

Based on the definition by Cadence, EDA encompasses software, hardware, and essential services used in the design of chips and semiconductor devices. Historically, hardware architects sketched chip designs by hand and used isolated tools. However, alongside the rapid growth of AI, EDA has become indispensable as chip designs get complicated. The tool provides a simulated environment where circuits and designs are conceived and analyzed before being realized in the physical world.

According to the report, as of March, 2023, X-Epic employed approximately 400 people across offices in Nanjing, Beijing, Shanghai, Chengdu, and Shenzhen. However, the company began laying off up to half its employees recently across various departments, including its key research and development division.

The report further analyzes that in In August 2022, Washington first restricted China’s access to the EDA technology by prohibiting the export of gate all-around (GAA) capable EDA software, which creates challenges for Chinese chipmakers in adopting advanced processes such as the 3nm node and in developing high-performance computing or AI chips.

Citing data from the China Semiconductor Industry Association, the report notes that the value of China’s EDA market is projected to reach 18.5 billion yuan (USD 2.55 billion) next year, up from 9.3 billion yuan in 2020. As the market seems to be booming, X-Epic’s reported layoff highlights the challenges China’s EDA companies are facing.

TrendForce’s investigations show that, among the three categories in the upstream semiconductor supply chain, which consist of semiconductor manufacturing equipment, materials, and EDA, China made the most progress regarding self-sufficiency in semiconductor equipment, followed by materials, with EDA coming in last, in 2020. In other words, Chinese companies are relatively slow to develop EDA solutions.

The EDA market is relatively oligopolistic and involves two US companies. That means once the US implements more stringent controls over the export of EDA technologies and products to China, China’s development of semiconductor self-sufficiency will most likely suffer dire consequences as a result. Even if Chinese domestic companies are able to supply semiconductor equipment for mature process nodes as well as technologies for chip design, manufacturing, and packaging/testing, these things are essentially inoperable without EDA software and technical support. That is to say, the EDA industry remains the final piece of the puzzle for China’s quest for semiconductor self-sufficiency. Since China’s new IC policies (termed the Policies for Promoting the High-Quality Development of the Integrated Circuit Industry and the Software Industry in the New Era) place more emphasis on semiconductor equipment, materials, and software, compared to past policies, EDA (for which China’s self-sufficiency rate is lower than 10%) will likely become the top developmental priority within the software category in the new IC policies.

Chinese EDA suppliers are likely to provide domestic substitute solutions for mature process nodes

As the Chinese semiconductor design and manufacturing industries continue to expand, the Chinese EDA software market is expected to grow at a 15.1% CAGR across 2020-2024, which is faster than the global average of 10.3%. Although Synopsys, Cadence, and Siemens still account for an approximately 80% share in the Chinese EDA market, domestic companies in China have been accelerating their pace of development in recent years. For instance, companies that have more than 10 years of experience developing EDA software, including S2C, Empyrean, Primarius, Xpeedic, NineCube, and Cellixsoft, are gradually making waves in the industry, while many other emerging companies, such as X-EPIC, Arcas, LEDA, and AMEDAC have also been attracting more attention in the EDA market recently. Now that China-US trade tensions have yet to be resolved, and China continues to proceed with its new IC policies, Chinese EDA suppliers will likely experience rapid growth going forward, especially in their attempt to create domestic substitutes for 28nm and other mature process technologies.
