When you gather a group of bright semiconductor folks in the middle of San Francisco and ask them what¡¯s the biggest future challenge they¡¯ll face, you¡¯re bound to get a bunch of interesting answers. That was the case at a recent AI-themed panel hosted by Renesas outside the Moscone Center on the edges of SEMICON West.  

Thoughts ranged widely. There was Advantest¡¯s Ira Leventhal, citing the challenge of getting semiconductor industry players to share more design data so everyone can learn faster¡ªsomething of a nirvana situation which may, or may not, ever be possible. Sailesh Chittipeddi from Renesas talked about the need to optimize the power efficiency of complex AI applications to radically reduce the amount of energy consumed. And Synopsys¡¯ own Shankar Krishnamoorthy considered the cost of increased chip design complexity and how generative AI (GenAI) could have a major positive impact on the electronic design automation (EDA) industry over the next five years.

Getting Into Details: Driving Innovation and Creating Value Across the Semiconductor Industry and Beyond

Krishnamoorthy started talking as a musician played Elton John¡¯s ¡°Tiny Dancer¡± on the street below. No tiny dancers on the panel but Krishnamoorthy was next to Evgeni Gousev from the TinyML Foundation. TinyML focuses on the deployment of AI on edge devices using inference techniques to create actionable insights locally. Chittipeddi noted that 75% of all data now comes from edge devices and with the quantity of data being crunched at the edge, and everywhere else, the semiconductor sector is racing towards becoming the first trillion-dollar industry.  

But with great growth comes even greater responsibility. The obvious challenges are oft discussed: is AI good or bad, what about data security and privacy, and how about the cloud¡¯s growing energy footprint¡ªespecially as heavy-duty workloads like ChatGPT become pervasive? But one key issue isn¡¯t quite so mainstream, and that¡¯s where Krishnamoorthy focused as he described the challenges of rapidly rising chip design complexity: ¡°Increasing productivity is crucial, as the cost of migrating complex chip designs to more advanced nodes has more than doubled in recent years while engineering staffing shortages have only grown more acute,¡± he explained. ¡°With 4x more work for engineering teams and a 10%-20% talent gap, AI-driven EDA tools are now a top priority for semiconductor companies.¡± 
 
Krishnamoorthy¡¯s point was that chip design becomes exponentially harder as transistors get ever smaller and that complexity is demanding more engineering resources than the industry can possibly provide. It¡¯s the perfect use case for AI to help us design more AI.  Leventhal was even more bullish, suggesting AI-powered tools will soon be ¡°fundamental¡± for chip design to boost engineers¡¯ productivity. Going even further, Leventhal proposed semiconductor companies should share AI-generated design data ¨C something that today they would never do. Making such an initiative possible would require companies to pool data on shared challenges in a secure way; each company would be able to gain insights from the new ecosystem data lake without any contributor accidentally giving away their secret sauce. It's theoretically possible, and the prospect is truly exciting.

Building a Sustainable Intelligent Edge with Lower-Energy Silicon

Sustainability was another hot topic for panel participants, with Chittipeddi talking about how performing more data processing at the edge was critical to balancing the load on the cloud. The reason being that cloud-based processing is far more energy-intensive overall due to the energy tax of moving data. The solution cuts across silicon and software. 

For software, Chittipeddi said AI developers must step up their ability to prune machine learning (ML) algorithms and models, enabling them to run more efficiently on purpose-built silicon such as low-power neural processing units (NPUs). Gousev continued the thread, stating that the ability to run workloads at the edge on tiny (often battery-operated) devices and drill for data had to be done with privacy in mind.

He quoted one local company seeing huge growth due to their development of specialized sensors and algorithms capable of obscuring faces and other identifiable information. This has opened opportunities to put cameras in sensitive areas such as restrooms to detect problems--for example, someone who had collapsed--without identifying the person. Now, while these edge devices run highly optimized ML models, emphasized Gousev, the software was fully reliant on the amount of processing power available. That brought us right back to chip design, and how AI could optimize the design of AI. 
 
As Synopsys¡¯ Krishnamoorthy told the audience, low-power chips (or any chips) are best designed with AI-driven EDA tools. He evidenced that with figures Synopsys was seeing with its Synopsys.ai? EDA solutions being used by designers to customize and differentiate silicon. ¡°We use AI to optimize AI, which is a great way to achieve 15% energy and power savings,¡± especially for edge devices.

Combining EDA Domain Knowledge and GenAI Expertise to Revolutionize Chip Design

Switching up a gear or two, the conversation shifted to reinforcement learning (RL) and how GenAI would soon be able to help chip designers overcome even greater challenges ¨C particularly when it comes to design complexity. As Renesas¡¯ Chittipeddi pointed out, only 54% of all AI-led programs succeed today, with the rest failing due to an inability to deal properly with design complexity and ease-of-use issues. The challenge for the panel, as for the industry, is that the use of GenAI for chip design is still theoretical as it is not yet fully accurate. As Krishnamoorthy said, a piece of content generated by ChatGPT can be 85% correct, but a chip design ¡°needs to be 100% accurate.¡±

Advantest¡¯s Leventhal was optimistic about the future, saying he looked forward to AI-driven EDA tools playing an even bigger role in helping his company design more complex test devices with increased speed and higher accuracy. Leventhal also pointed to evolving GenAI technologies such as ChatGPT 4, which could spawn a new generation of interactive AI applications and enable engineers to make more impactful decisions in real time. Leventhal¡¯s observation sparked an exchange of ideas about GenAI use cases (both present and future), including using AI-powered assistants such as GitHub Copilot to assist engineering teams with register transfer level (RTL) code suggestions, summarization, migration, and review tasks. Similarly, specialized chatbots could provide contextual understanding and recommendations for tools, with generative search allowing engineers to rapidly sort through extremely large datasets and minimize debug errors.   
 
Noting ¡°companies must disrupt, or they will be disrupted,¡± Synopsys¡¯ Krishnamoorthy emphasized that AI-driven EDA tools must function consistently and accurately throughout the semiconductor supply chain. ¡°GenAI tools will fall short unless they holistically combine EDA domain knowledge and AI expertise, which is why development teams must have an understanding of the complex chip design world and changing AI landscape,¡± he explained. ¡°AI is rapidly evolving, and while we will undoubtedly see some GenAI ¡®killer apps¡¯ during this sunrise stage, others may fade away. As GenAI matures and is easier to use, it will become mainstream for many uses cases, whether designing chips or creating slides.¡± 
 
Krishnamoorthy pointed out that Synopsys.ai, the industry¡¯s first full-stack AI-driven EDA suite, is enabling major semiconductor companies to significantly improve efficiency and reduce development cycles across analog design migration, digital design, verification, and testing. ¡°We are thrilled and excited to see what our customers have achieved with Synopsys.ai over the past year,¡± he added. ¡°Chip designers are accomplishing significantly more¡ªand faster¡ªwithout expanding headcount. We are tracking over 250 completed production designs for DSO.ai? (Design Space Optimization AI) ²¹±ô´Ç²Ô±ð.¡±&²Ô²ú²õ±è;
 
Krishnamoorthy concluded his panel contribution by noting Synopsys¡¯ AI journey was only just beginning, as many EDA tools, including those used for technology computer-aided design (TCAD), rapid node migration for analog designs, and various stages of manufacturing will also benefit tremendously from advanced AI capabilities.
