CompoundTek Collaborates with Cadence and Lumerical to Deliver Integrated Electronic-Photonic Design Automation PDK for Silicon Photonics ICs

New advanced EPDA flow supports the continued development of SiPh solutions.

CompoundTek, a global foundry services leader in emerging silicon photonic (SiPh) solutions, today announced that it has collaborated with Cadence Design Systems, Inc. and leading photonics design and simulation provider, Lumerical, on the delivery of a new CompoundTek process design kit (PDK) for SiPh ICs. The PDK consists of a new, advanced electronic-photonic design automation (EPDA) flow with features aimed at further advancing the development of differentiated SiPh solutions.

The PDK is based on the Cadence® Virtuoso® custom IC design platform, utilizing the Cadence CurvyCore engine, Cadence Spectre® simulation platform and the electrical-optical co-simulation capability in Lumerical’s photonic integrated circuit simulator INTERCONNECT. The kit includes active and passive devices such as optical waveguide devices, fiber-to-waveguide couplers, high-speed waveguide Ge photo-detectors and high-speed modulators to enable SiPh designers to design and verify their photonics products more quickly and efficiently before fabricating physical prototypes.

“Our strategic collaboration with Cadence and Lumerical enables customers to leverage an integrated EPDA PDK, which features an open SiPh manufacturing platform to accelerate the adoption of SiPh solutions for various applications ranging from datacom transceivers, smart sensor, bio-medical, automotive lidar, quantum computing and artificial intelligence,” said KS Ang, chief operation officer of CompoundTek.

SiPh mask geometries and their curvilinear shapes introduce unique challenges for layout designers. Using the Cadence CurvyCore™ technology, users of the CompoundTek PDK can systematically manage curvilinear shapes within the Cadence Virtuoso design environment. Similarly, having an ecosystem that supports simulation of electrical and optical parts of large systems together, including complex electro-optical effects that must be co-simulated, facilitates the development of larger and more complex integrated electronic-photonic circuits and systems. This PDK helps customers overcome both of these challenges.

“As the market moves toward more highly integrated electro-optical designs, accurate co-simulation of electrical and optical components becomes critical,” said Dr. James Pond, chief technology officer of Lumerical. “CML Compiler allows foundries and end users to easily build and maintain accurate photonic compact models for co-simulation with Cadence Spectre Simulator and Lumerical INTERCONNECT. Our collaboration with CompoundTek and Cadence is enabling these key capabilities for our customers.”

“Through our collaboration with CompoundTek and Lumerical, customers can now design photonics IC chips, leveraging the complete Virtuoso platform, from high-performance curvilinear shape generation with CurvyCore-based PCells to entire system-level thermal and EM analysis,” said Glen Clark, corporate vice president research and development, in the Custom IC & PCB Group at Cadence. “The PDK incorporates the Cadence schematic and layout-driven photonics design flow, enabling mutual customers to achieve SoC design excellence and deliver products to market faster.”
