Enhancing Chip Design with Cadence's AI-Powered Voltus InsightAI Solution

Cadence's Innovative Leap in EDA


In the rapidly evolving landscape of electronics, Cadence has taken a significant step forward with the introduction of Voltus InsightAI, a groundbreaking technology that leverages artificial intelligence in Electronic Design Automation (EDA). The increasing integration of AI in various applications has resulted in complex challenges for chip designers, particularly in relation to power, performance, and area (PPA). This new release from Cadence aims to tackle these intricacies head-on.

The evolving demands of the semiconductor industry have put chip designers under pressure to create devices that are not only smaller and faster but also consume less power. As we move towards advanced manufacturing nodes, especially those under 5nm, these challenges multiply exponentially. The sheer number of electromigration (EM) and IR drop violations presents a daunting task for designers—one that often requires extensive manual efforts to assure compliance with design objectives.

The Challenge of Power Integrity


One of the most critical challenges faced at advanced nodes is maintaining power integrity. Traditionally, designers have struggled with substantial numbers of violations at design sign-off, making it imperative to address power integrity issues early in the design process. Cadence recognized this drawback and incorporated AI into their design solutions to provide an innovative approach.

Voltus InsightAI is positioned as the first generative AI technology designed specifically to automatically identify the root causes of EM-IR drop violations during the design phase, paving the way for effective fixes that contribute to improved PPA metrics. According to Albert Zeng, the Senior Software Engineering Group Director at Cadence, the system uses advanced AI technologies to derive the most efficient ways to enhance designs while integrating seamlessly into the existing Cadence Innovus Implementation System.

Another noteworthy feature of Voltus InsightAI is its computational efficiency. In a landscape where computational resources can be stretched thin due to the enormous size and complexity of power networks, this technology drastically reduces the time and resources required to resolve up to 95% of violations before final sign-off. This capability is particularly advantageous in the context of large designs where manually managing violations would be impossible.

Transforming Challenges into Opportunities


Zeng asserts that Voltus InsightAI is essential for helping customers enhance both on-chip and chiplet power integrity. With its fast IR inferencing engines, IR drop diagnostics, and multi-method fixing capabilities, it empowers chip designers to unveil issues early, thereby significantly improving workflow efficiency.

Unlike any competitor solutions on the market, Voltus InsightAI is built on Cadence's reputation for delivering signoff-quality analysis. This inherent integration not only streamlines the user experience but also ensures that any modifications made throughout the design process correlate accurately with final sign-off data. Zeng emphasizes that this unique advantage positions Cadence as the only EDA vendor offering a combined solution that includes both implementation and power integrity technology.

Recognizing Innovation


In acknowledgment of these remarkable advancements, Voltus InsightAI received the prestigious Innovation RD Award at the EE Awards Asia 2024. This recognition serves not only as validation of Cadence’s efforts but also as motivation for the team to continue exploring innovative solutions. Zeng conveyed gratitude towards his team, highlighting the collaborative work that enabled the development of this significant tool even amidst initial skepticism.

Looking Towards the Future


With the initial success of the Voltus InsightAI platform, Cadence is committed to continuous improvement and refinement of its capabilities. The company has already integrated feedback from leading-edge customers into the evolving technology, which will help in releasing subsequent updates to further enrich user experience.

As AI continues to revolutionize the EDA sector, Zeng anticipates a trajectory that will enhance productivity across various stages of design, including early exploration and optimization processes. The integration of AI is not merely a trend but is expected to fundamentally reshape how electronic design is approached, ultimately benefiting new engineers by helping them navigate complex design challenges.

In summary, Cadence's Voltus InsightAI is not just an innovative solution addressing immediate EDA challenges but also a promising glimpse into the future of chip design powered by AI, setting the stage for even more advanced development in the years to come.
