Open Chiplet EconomyThe Open Chiplet Economy Sub-Project is under the direction of the OCP Server Project Group.

Just as a strategy of modularization has impacted data center hardware at large, from design and operations, so too is this trend coming to the foundations of computing. High-performance and domain-specific system-on-chip (SoC) compute architectures have grown larger and more expensive to produce, and chiplets are the disaggregated, modular equivalent with new advanced 2D and 3D system-in-package (SiP) engineering. This Open Chiplet Economy OCP Subproject and corresponding area of the OCP Marketplace is where the OCP Community applies open collaboration and standardization across the scope of chiplets.

Scope

The Open Chiplet Economy Subproject is where the upstream work happens in the Community. It deals with multiple aspects of building a selection of chiplets into a SiP . The main aspects to this work are,

  1. the Electronic Design Automation (EDA) tools/flows needed to enable the chiplet based design workflows,
  2. the collateral needed to build a SiP consisting of chiplets with a business component that looks at the economics of chiplets and how that changes the marketplace, and
  3. the interfaces that connect chiplets together.

Each of these categories has a number of workstreams working collaboratively to develop coherent specs, white papers, methodologies, etc. for an open chiplet market to thrive.
