Targeting 400Gb and 800Gb optical fiber applications in data center and telecommunications markets

MIGDAL HAEMEK, Israel, San Jose, CA and Vancouver, BC,July 10, 2019TowerJazz, the global specialty foundry leader, Cadence Design Systems, Inc. (NASDAQ: CDNS), and Lumerical Inc., a leading developer of photonic design and simulation tools, today announced the availability of a complete custom design Silicon Photonics (SiPho) and Silicon Germanium (SiGe) integrated process design kit (PDK). The differentiated PDK is based on the Cadence® Virtuoso® custom IC design platform, providing native synthesis using the Cadence CurvyCore engine and Electrical-Optical co-simulation capability in Lumerical’s photonic integrated circuit simulator INTERCONNECT. The complete, photonics-optimized solution provides SiPho designers with a single, streamlined design environment for developing complex multi-fabric systems, while enabling them to collaborate in a shared IC design environment to leverage the electro-optical interface that is critical for enabling 400GB optical transceivers.

“We are excited to expand our industry-leading SiPho technology, and to be the first major foundry to offer, through this collaboration with Cadence and Lumerical, the co-optimization of electrical SiGe and optical SiPho components in a single EDA environment,” said Marco Racanelli, senior vice president and general manager of the Analog IC Business Unit at TowerJazz. “This new capability enables our mutual customers to shortcut development cycles and accelerate the introduction of 400Gb and 800Gb breakthrough products.”

Customers using the new TowerJazz PDK can now confidently synthesize non-Manhattan shaped photonics designs utilizing the Cadence CurvyCore technology, which allows to systematically manage curvilinear shapes within the Cadence Virtuoso design environment using its high-performance shape generation and manipulation infrastructure with dedicated SKILL API.
Delivery of the new TowerJazz PDK encompasses the previously available Lumerical Compact Model Library (CML) to enable a proven, complete solution incorporating co-simulation utilizing industry leading tools.

“TowerJazz and Cadence customers can begin leveraging the high-performance shape generation technology within the Virtuoso design environment to further advance the development of complete multi-chip photonics systems,” said Glen Clark, Vice President, Research and Development at Cadence. “TowerJazz, Lumerical and Cadence have a long history of collaboration that enables our mutual customers to achieve success in delivering quality products to market faster and easier.”

“A touchstone of the commercialization of photonics is ecosystem development by world class companies,” said James Pond, Lumerical CTO. “Our partnership with Cadence and TowerJazz enables photonic integrated circuit designers to co-simulate their electro-optical and photonic components using leading tools they are familiar with, and fabricate those designs at TowerJazz, a foundry they have utmost confidence in.”
