Rapidus Corporation and Cadence Design Systems Inc. (Nasdaq: CDNS) have announced a collaboration to advance agentic artificial intelligence (AI) capabilities for advanced-node system-on-chip (SoC) design by integrating Cadence’s InnoStack™ AI Super Agent into Rapidus’ AI-Agentic Design Solution (Raads).
The partnership combines Rapidus’ AI-focused semiconductor design and manufacturing ecosystem with Cadence’s AI-driven design orchestration technology to help engineering teams improve productivity, accelerate development cycles and enhance design quality across the SoC lifecycle.
As part of the collaboration, Rapidus is targeting up to a two-fold improvement in design turnaround time (TAT) compared with conventional design flows.
The companies said the growing demand for AI infrastructure and physical AI-powered systems requires greater coordination across semiconductor design, manufacturing, packaging and system-level optimisation. Agentic AI, which enables autonomous AI agents to coordinate complex workflows, is expected to play a key role in managing the increasing complexity of advanced semiconductor designs.
Under the collaboration, Rapidus is expanding its Raads platform with two new capabilities — Raads Navigator and Raads Indicator. The tools are designed to support quality assurance processes and help engineers identify and resolve design challenges more efficiently.
The integration with Cadence InnoStack AI Super Agent enables AI-driven orchestration across critical SoC workflows, covering activities from early architectural exploration to implementation and final signoff. The companies said the combined platform uses data-driven optimisation to improve design predictability, manage advanced-node complexity and scale engineering productivity.
“Advanced-node SoC design increasingly requires AI agents that can orchestrate complex workflows across the design lifecycle, not just optimise individual tasks,” said Anirudh Devgan, President and CEO of Cadence.
He said integrating Cadence’s InnoStack AI Super Agent with Rapidus’ Raads platform extends agentic AI capabilities into an advanced semiconductor ecosystem, helping customers improve productivity and accelerate silicon development.
Rapidus is developing its Innovative Integration for Manufacturing facility as an AI-native semiconductor manufacturing site, where artificial intelligence will be integrated across multiple stages of chip production.
“At its completion, our Innovative Integration for Manufacturing facility will be the most advanced, AI-native foundry where AI is incorporated at almost every stage of semiconductor manufacturing,” said Atsuyoshi Koike, Representative Director and CEO of Rapidus.
Koike said the integration of Raads with Cadence’s AI Super Agent technologies will help customers address rising SoC complexity, improve engineering efficiency and maximise the capabilities of Rapidus’ advanced process technologies.
The companies will highlight the collaboration at CadenceLIVE Japan 2026, where Koike will discuss Rapidus’ development of Raads and the role of AI-driven electronic design automation (EDA) in improving advanced-node SoC development.
