On September 23, Cadence Design rose 3.04% in regular trading, trading at $313.31 per share, with turnover of $61.9966 million. The gain follows the company's announcement of an expansion to its Chipstack AI super-agent platform, introducing new intelligent agents focused on RTL generation and early-stage PPA (Performance, Power, and Area) optimization.

The new agents are designed to help chip design teams capture and optimize core metrics at earlier stages of the design cycle, shortening front-end timelines and laying a stronger foundation for downstream optimization. This product enhancement reflects growing industry demand for more intelligent, automated EDA tools driven by AI. The move also builds on the company's strong momentum from Q2, where revenue grew 24% year-over-year to $15.8 billion, non-GAAP EPS rose to $2.11, and operating margin expanded to 45.5%, prompting management to raise full-year guidance.

Additionally, Cadence Design was highlighted as a key beneficiary in the EDA segment amid broader semiconductor industry discussions around advanced packaging and system-level interconnect optimization trends.
