About this Webinar

We’ll highlight a collaborative project with HPE where Ansys HFSS and Ansys Lumerical INTERCONNECT were used with other Ansys tools for design scoping, optimization, and multiphysics analyses of an electronic-photonic 3D-IC transceiver for PCI express with co-packaged optics for data center applications. We’ll show signal and power integrity analyses’ results and how TSV configuration, package channel length, receiver-side equalization, and RDL densities achieved an overall system data rate of 384 Gb/s.  On the photonics side, we will show a novel optimization technique and a workflow for thermal power budgeting in co-packaged optics.
