OCP and JEDEC advance chiplet design

The Open Compute Project Foundation (OCP) and JEDEC announced a collaboration to revolutionize chiplet design, manufacturing and integration.

In a significant development, the integration of OCP CDXML into JEP30 has reached a critical milestone, enabling chiplet builders to provide standardized chiplet part descriptions to their customers electronically. This advancement opens the door to automating System in Package (SiP) design and assembly using chiplets. The chiplet descriptions encompass crucial information for SiP builders, including thermal properties, physical and mechanical requirements, behavior specifications, power and signal integrity properties, testing in-package and security parameters.

The Chiplet Design Exchange (CDX), an open-source working group operating in the Open Domain-Specific Architecture (ODSA) sub-project within the Open Compute Project, comprises a team of experts from diverse fields, including EDA, system design, IC and SiP design, OSAT, IC fabrication and material supply. Their collective mission, and that of the OCP ODSA Project, revolves around nurturing a flourishing open chiplet economy. The CDX group presented a whitepaper at the IEEE 3DIC 2021 conference in October 2021, introducing standardized chiplet models designed for development and validation of 3D IC designs. While many of these models drew from established standards, a standout innovation emerged in the form of machine-readable models for electrical and mechanical properties, which have since evolved into the JEDEC JEP30 PartModels. These models form the foundation of a Chiplet Design Kit (CDK).

“The integration of JEDEC JEP30 and OCP CDXML is truly a groundbreaking endeavor, creating a unified platform that revolutionizes chiplet and electronic part integration,” said Michael Durkan, JEDEC Task Group Chair and PartModel Sponsor. He continued: “Enabling component manufacturers to create standardized digital part models that can be easily used by designers and engineers in all varieties of electronic systems will help propel the industry forward with next-level digitalization and automation.”

“By uniting the power of OCP CDXML and JEDEC JEP30 standards, we are forging a new era of collaboration and innovation in the chiplet industry. This integration empowers engineers, manufacturers and designers with a comprehensive framework that enhances efficiency, compatibility and customization,” said Cliff Grossner, Ph.D., Chief Innovation Officer with OCP. He added: “The OCP CDXML-JEDEC JEP30 collaboration embodies OCP’s value proposition and its commitment to driving progress and elevating the industry as a whole.”


Nokia carries 800G single wavelength over 7865 km

Nokia announced two new world records in submarine optical transmission: 

  • 800 Gbps on a single optical wavelength at a distance of 7865 km – the distance between Tokyo and Seattle. Nokia Bell Labs achieved this milestone at its optical research testbed in Paris-Saclay, France.
  • a net throughput of 41 Tbps over 291 km via a C-band unrepeated transmission system. This record was achieved by both Nokia Bell Labs and Nokia subsidiary Alcatel Submarine Networks (ASN).  C-band unrepeated systems are commonly used to connect islands and offshore platforms to each other and the mainland proper. The previous record for these kinds of systems is 35 Tbps over the same distance. Nokia Bell Labs and ASN broke the record at ASN’s research testbed facility, also in Paris-Saclay.

Nokia said the achievements were made possible by higher-baud-rate technologies. The research behind these two records will have significant impact on the next generation of submarine optical transmission systems. While future deployments of submarine fiber will take advantage of new fiber technologies like multimode and multicore, the existing undersea fiber networks can take advantage of next-generation higher-baud-rate transceivers to boost their performance and increase their long-term viability.  

Sylvain Almonacil, Research Engineer at Nokia Bell Labs, said: “With these higher baud rates, we can directly link most of the world’s continents with 800 Gbps of capacity over individual wavelengths. Previously, these distances were inconceivable for that capacity. Furthermore, we’re not resting on our achievement. This world record is the next step toward next-generation Terabit-per-second submarine transmissions over individual wavelengths.”

Hans Bissessur, Unrepeated Systems Group leader at ASN, said: “These research advances show that that we can achieve better performance over the existing fiber infrastructure. Whether these optical systems are crisscrossing the world or linking the islands of an archipelago, we can extend their lifespans.”
