Silicon-photonics and SiGe-integrated PDK targets 400Gb/800Gb applications
TowerJazz, Cadence Design Systems, and Lumerical have 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.

CurvyCore allows designers to create and edit complex curvilinear shapes common in photonics, MEMs, microfluidics and conformal metal routing.

“This new capability enables our mutual customers to shortcut development cycles and accelerate the introduction of 400Gb and 800Gb breakthrough products,” said Marco Racanelli, senior vice president and general manager of the Analog IC Business Unit at TowerJazz.

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.
