Paper Title: Annual Update on Interfaces

Paper Abstract: The common die-to-die interfaces for multi-die systems (or chiplets) today are BoW (Bunch of Wires) from the Open Compute Project (OCP) and UCIe (Universal Chiplet Interface Express) from the UCIe Consortium. Both are open standards that support many architectures and have emerging ecosystems. Both offer high throughput, low latency, low power consumption, and small chip area requirements. Both have governing bodies that will issue extensions and revisions and provide training, education, and other support. Designers must determine which is best suited for their applications currently and which offers the best forward path for later updates and product families and generations.
