Abstract

Chiplet technology can significantly reduce the cost and time needed to develop custom high-performance silicon products. To realize a chiplet-based product, a die-to-die (D2D) network to interconnect the chiplets is required. Almost all of today's chiplet-based products use proprietary D2D interfaces. Industry has primarily paid attention to D2D PHYs. A design also requires logical information flow between chiplets. Current designs use proprietary PHYs and logic protocols between components. This approach makes it challenging to integrate chiplets from multiple vendors. The open domain-specific architecture (ODSA) is a project within the open compute project (OCP) community that aims to establish open physical and logical D2D interfaces for chiplets. Ultimately, the ODSA aims to create open interfaces to enable a marketplace of interoperable chiplets. This will allow product designers to develop chiplet-based products that integrate best in class chiplets from multiple vendors. This article reviews technical developments within the ODSA.
