Advanced chipset testing for pre-silicon verification


Spirent and Cadence joint solution accelerates silicon development time to market to enable the latest industry innovations.

Spirent Communications is working with Cadence Design Systems, Inc., to deliver a joint networking system-on-chip (SoC) verification solution that bridges the gap between pre-silicon and post-silicon verification.

The collaboration brings sophisticated virtual Ethernet traffic emulation and testing capabilities to pre-silicon verification in the Cadence Palladium® Z2 Enterprise Emulation and Protium™ X2 Enterprise Prototyping systems. Highly scalable and flexible, the solution has the capacity to emulate any port speed from 1G to 800G at the application level, and quickly introduce additional features to enable new use cases as required.

Jointly developed by Spirent and Cadence, the solution is designed to enable the increasing data bandwidths needed to verify designs for data centers and other high-performance applications. The partnership combines the cutting-edge data rates and port densities of Spirent TestCenter with the industry-leading verification capabilities of the Cadence Palladium and Protium systems as a unified solution with reusable, portable, automated test cases.

“We are pleased to work with a leading computational software vendor to bridge the gap between pre- and post-silicon validation of next-generation networking products with this highly flexible and cost-effective solution,” said Aniket Khosla, VP of product management for Cloud and IP at Spirent. “Our collaboration with Cadence provides access to the latest Chip Design Verification solution to help customers identify critical problems early in the design lifecycle and accelerate time to market for the latest innovations driving the industry. It will help reduce development time, simplify testing of the complex Ethernet chipset design process, and ensure that new products perform as expected.”

Michael Young, senior product management group director, System and Verification Group at Cadence said: “Through our work with Spirent, Cadence is continuing our commitment to work with industry leaders to bring best-in-class solutions to the pre-silicon verification market. When integrated into the Palladium emulation and Protium prototyping systems, Spirent’s’ Ethernet traffic emulation and test capabilities allow mutual customers to extend their verification with real-world traffic and scenarios, greatly reducing time to market.”

Benefits of the joint solution include:

Effective, efficient testing for pre-silicon validation from 1G to 800G for application-level testing,

Comprehensive integration of the test application and emulation environment without the need for external test hardware,

Cost savings from identifying and fixing issues in early-stage chip design

A unified test platform that bridges gaps between pre- and post-silicon verification, enabling continuity of testing from the earliest phases of product development through customer deployment

Capability to test all phases of silicon product lifecycle, time-saving application re-utilization, implementation of standard metrics for more effective measurement and result analysis, and easy integration into CI/CD workflows,

Acceleration of the entire silicon development lifecycle.

“Chip design is time-intensive, testing early at the pre-silicon design phase helps speed up time to market for the latest industry innovations by reducing issues and risks later in the development cycle” says Khosla. “The new unified test platform reduces testing complexity and accelerates the technology design and development of Ethernet chipsets.”
