Leti Innovates with Chiplets and Automated Design Tools

CEA-Leti, a leading French research group based in Grenoble, has unveiled a groundbreaking chiplet architecture tailored for the automotive industry. This innovative approach is complemented by the development of cutting-edge automated tools aimed at enhancing design exploration processes.

The automotive sector's transition towards software-defined vehicles and zonal architectures has spurred the demand for chiplets and advanced design tools at CEA-Leti. Denis Dutoit, the programme manager for advanced computing and chiplets at CEA-Leti, highlighted the group's collaboration with a major automotive OEM to conceptualize high-level E/E architectures.

During the Leti Innovation Day, the chiplet architecture was showcased, signaling a significant leap in automotive design methodologies. Dutoit emphasized the necessity for a fresh approach due to the vast design space, rendering traditional methods obsolete.

With the evolution towards zonal architectures in the next generation of E/E systems, the industry faces scalability challenges. The disparity in compute power and memory bandwidth between low-end and high-end solutions underscores the need for a more efficient and cost-effective approach.

CEA-Leti's strategy involves segmenting systems based on physical location, with a focus on central compute in zonal architectures. The development of specialized chiplets, such as the IO chiplet for low-end applications and the ADAS chiplet for advanced driver-assistance systems, showcases the group's commitment to addressing diverse automotive requirements.
