Paper Title: Using a Markup Language in Chiplet-Based Design

Paper Abstract: The design of chiplet-based systems requires detailed modeling of chiplet components and assemblies. EDA tools from different vendors must import chiplet models and combine them into systems to design and productize heterogeneous integrated circuits successfully. The design process requires in-depth chiplet data for electrical, mechanical, power, thermal, and testability analysis. Hence designers need a standard model for chiplets and their associated components. The CDXML specification defined by the Open Compute Project Foundation addresses the challenges facing chiplet modeling and design automation. CDXML describes chiplet data using the eXtensible Markup Language (XML) format with an XML Schema Definition. The data is grouped according to type such as mechanical, IO, and electrical. An example project illustrates the use of the specification through the stages of 2.5D and 3D IC chiplet-based design.
