Ansys, TSMC Enable Multiphysics Platform for Optics, Photonics Solutions

Ansys and TSMC deliver a high-fidelity multiphysics solution to address design challenges for artificial intelligence (AI), datacenter, cloud, and high-performance computing (HPC) chips


Ansys announced a collaboration with TSMC on multiphysics software for TSMC’s Compact Universal Photonic Engines (COUPE). COUPE is a cutting-edge Silicon Photonics (SiPh) integration system and Co-Packaged Optics platform that mitigates coupling loss while significantly accelerating chip-to-chip and machine-to-machine communication.

TSMC COUPE, along with Ansys multiphysics solutions that are integrated with Synopsys’ 3DIC Compiler unified exploration-to-signoff platform, enables the next generation of silicon photonics and co-packaged optics designs for applications in AI, datacenter, cloud, and HPC communications. The work spans multiple areas, including fiber-to-chip coupling, integrated electronic-photonic chip design, power integrity verification, high-frequency electromagnetic analysis, and critical thermal management.

TSMC COUPE integrates multiple electrical ICs with a photonic IC and fiber optic connections into a single package. These include Ansys Zemax for optical input/output simulation, Ansys Lumerical for photonic simulation, Ansys RedHawk-SC and Ansys Totem for multi-die power integrity signoff, Ansys RaptorX to model high-frequency electromagnetic analysis between dies, and Ansys RedHawk-SC Electrothermal for vital thermal management of the multi-die heterogenous system. Additionally, Lumerical allows custom Verilog-A models for electronic photonic circuit simulations, which work seamlessly with the TSMC Modeling Interface (TMI) and are co-designed with TSMC’s Process Design Kit (PDK).

“By providing a good silicon photonics integration system we can address both critical issues of energy efficiency and computing performance to support the explosive growth in data transmission that comes with the AI boom,” said Dan Kochpatcharin, head of the design infrastructure management division at TSMC. “We have aligned closely with our Open Innovation Platform® (OIP) partners like Ansys to provide our customers with a solution to the design challenges in this breakthrough technology, enabling their designs to achieve a new level of performance and energy efficiency.”

“Ansys’ multiphysics platform for TSMC’s COUPE technology underscores our focus on delivering the most comprehensive multiphysics portfolio with the best solution for every need,” said John Lee, vice president and general manager of the semiconductor, electronics, and optics business unit at Ansys. “Ansys is a leader in delivering a deep and broad portfolio of integrated multiphysics simulation solutions and platforms. Together, TSMC and Ansys are enabling the next wave of technological innovation.”
