Spreadtrum Communications, a leading provider of baseband and RF processor solutions for the wireless communications market in China, recently adopted Cadence® Silicon Realization technologies and successfully taped out its first 40-nanometer low-power chip.

Today, mixed-signal design goes far beyond the typical importation of hard analog macros into a digital system-on-chip (SoC). It also involves the creation of full custom digital, analog, and RF IP blocks and integrated circuits. And it means integrating blocks into SoCs that support broad ranges of functionality. The fundamental challenge: being able to concurrently tackle functional, electrical, and physical requirements.

The Cadence approach to Silicon Realization is an end-to-end deterministic path that concurrently optimizes functionality, electrical specifications, and physical requirements. This holistic approach to silicon design, implementation, and verification hinges on three critical requirements: design intent, abstraction, and convergence.

With Cadence tools for consistent representation of design intent, higher levels of abstraction with accurate models, and early visibility into late-stage design and manufacturing data to ensure convergence on goals, Spreadtrum can now prevent silicon failures, adopt more advanced process nodes without the risk, and stay competitive in the global marketplace.

“Time to market, power consumption, performance, and cost efficiency are some of our major concerns at Spreadtrum as we compete in the highly competitive mobile communications market,” said Leo Li, Chairman and CEO at Spreadtrum. “We needed an EDA company that shares our vision and commitment to make it possible to create and deliver differentiated SoC solutions. Cadence and its Silicon Realization products were the clear choice for us. This 40-nanometer chip's one-pass success demonstrated our ability to deliver cutting-edge technology to the 3G communications industry and showcased the capability of our world-class design team with an effective and high-quality development process.”

By consolidating on the end-to-end Cadence Silicon Realization product line, Spreadtrum now has the competitive advantages that result from a deterministic path to silicon.
