In a groundbreaking announcement at CadenceLIVE Silicon Valley 2026, Cadence has introduced two innovative AI Super Agents—ViraStack and InnoStack—propelling chip design into a new era of automation. These agents, combined with the previously released ChipStack AI Super Agent, cover the entire chip design process from specification to signoff. The AgentStack head agent orchestrates all these Super Agents, enhancing efficiency and collaboration across the chip design spectrum.
**Entering the AI-First Era of EDA**
The growing role of AI in electronic design automation (EDA) marks a shift toward greater autonomy and efficiency. Unlike general-purpose large language models that rely on probabilistic intuition, Cadence’s AI Super Agents integrate LLM-based generative capabilities with rigorous EDA tools. By adopting a structured agentic workflow, these tools break down complex tasks into manageable sub-tasks. The mental models and Cadence Native Skills ensure the alignment of AI actions with engineering principles, providing reliability and accuracy in design outcomes.
**The ChipStack AI Super Agent: Digital Design and Verification**
ChipStack revolutionizes digital RTL design, offering autonomous facilitation of design, verification, and debugging. It efficiently transforms design specifications into working RTL and testbenches, ensuring the implementation meets the outlined specifications. The automation provided by ChipStack reduces the manual workload, speeding up the verification process while maintaining accuracy and reliability.
**ViraStack: Transforming Analog Design**
ViraStack brings its agentic prowess to the traditionally labor-intensive field of analog design. By focusing on schematic creation, circuit optimization, and layout migration, ViraStack helps designers navigate performance, power, and reliability trade-offs. The agent can mine rich libraries of existing analog IP, assisting firms in upgrading older schematics to align with modern specifications.
**InnoStack: From Digital Implementation to Signoff**
Addressing digital design implementation, the InnoStack AI Super Agent covers everything from synthesis to signoff analysis. It optimizes design spaces by fine-tuning constraints and conducting parallel experiments. The result is a streamlined, automated process that uncovers optimizations for performance, timing, power, and area goals, paving the way for quicker convergence and closure.
**Engineering, Accelerated**
Cadence’s AI Super Agents, under the guidance of AgentStack, present a holistic approach to chip design automation. The powerful tools aim to replace time-consuming manual processes with expedient, AI-driven methodologies capable of operating at unprecedented speeds and accuracy, thus reimagining the landscape of electronic design automation. The ChipStack AI Super Agent is ready for customer deployment, while ViraStack and InnoStack are currently engaging with developmental partners, indicating a fast-paced future for chip design innovation.
