Key Terms

asic technical

ASIC is Australia’s corporate, markets and financial services regulator that enforces rules for companies, financial advisers and market operators; think of it as the referee and rulebook keeper for financial activity. It matters to investors because ASIC’s oversight, investigations and enforcement actions affect company credibility, legal risk and market fairness—actions that can change stock prices, investor confidence and the safety of financial products.

tape-out technical

Tape-out is the milestone when a chip designer delivers the finalized, production-ready blueprint of a semiconductor chip to a foundry for fabrication. Think of it as handing a finished blueprint to a factory: it means design work is complete and manufacturing (with its costs and timelines) can begin. For investors, tape-out signals a clear step toward production, potential revenue, and the transition of technical risk into manufacturing and market risk.

electromagnetic simulation technical

Electromagnetic simulation is a computer-based method for modeling how electric and magnetic fields behave around devices, circuits or systems, letting engineers predict performance without building physical prototypes. Investors care because it speeds product development, reduces costly design errors, and helps foresee issues like signal interference or regulatory compliance—similar to using a virtual wind tunnel to test a car’s aerodynamics before making one.

sub-thz technical

Sub-THz (sub-terahertz) describes electromagnetic waves with frequencies just below one terahertz (1 THz), typically in the range from about 100 gigahertz up to 1 THz. Like the upper end of Wi‑Fi or microwave bands stretched toward light, these frequencies enable very high-speed wireless links, detailed imaging, and compact sensors; investors watch sub-THz technologies because they affect the design, regulation, and market potential of communications, sensing, and semiconductor products.

AI infrastructure silicon delivered from concept to tape-out in under six weeks

SANTA ROSA, Calif.--(BUSINESS WIRE)-- Keysight Technologies, Inc. (NYSE: KEYS) today announced that AttoTude Inc., a pioneer of next-generation ASICs over Dielectric interconnect technology for AI and hyperscale data center applications, has expanded its use of Keysight EDA software to manage its full IC design workflow. As a result, AttoTude has reduced its design cycles by more than 50% while achieving first-pass silicon success across advanced RF, sub-THz, and THz tape-outs that underpin its guided-wave interconnect platform.

Design velocity is emerging as a competitive advantage, with global semiconductor revenue forecast to exceed $1.3 trillion in 2026 and AI semiconductors expected to account for 30% of the market. For organizations developing AI interconnect technologies, accelerating silicon development while minimizing costly respins is vital to delivering the required bandwidth, efficiency, and scalability.

AttoTude designs integrated circuits that support per-lane data rates of 200G, 400G, and 800G, where on-chip interconnects behave as waveguides and accurate electromagnetic simulation is essential. With engineers working in parallel on sub-THz and THz subsystems, coordinating workloads without a shared, version-controlled environment makes first-pass silicon success difficult to achieve at scale. With the Keysight Advanced Design System (ADS) platform, AttoTude has cut design cycles to less than six weeks, with designs consistently performing to specification on first silicon.

Utilizing Keysight's design data management software, AttoTude maintains a single source of truth across its design environment, giving engineers full traceability and visibility at every stage. System-level scenario planning allows the team to explore design trade-offs before committing to silicon, with simulation-to-measurement correlation ensuring results reflect performance. As operating frequencies extend from RF into the sub-THz and THz domains, maintaining consistency between layouts, electromagnetic models, and simulation data becomes critical to delivering reliable silicon.

Richard Chan, ASIC Architect and Development Leader, AttoTude, said: “Developing an ASICs over Dielectric interconnect platform that spans signaling frequencies from 100 GHz to 3 THz requires an exceptional level of design accuracy and simulation fidelity. Keysight’s EDA software has enabled our engineering team to move faster with greater confidence, helping us accelerate development while consistently achieving first-pass silicon success.”

Nilesh Kamdar, General Manager, Keysight EDA, said: “At Keysight, we measure success by what our customers achieve. The next generation of AI infrastructure will be built by the teams that move from design to silicon fastest, and AttoTude is proving what that speed makes possible.”
