Many features of UCIe 2.0 seen as “heavy” are optional, causing confusion.
The spec is defined with so many variants that you can tailor it to your exact needs. It’s applicable for everything from automotive to high-performance compute to AI to mil/aero because it has so many flavors. That’s also a curse to an IP provider. How do you support all those flavors?”
the latter predominates, since virtually all projects underway are internal projects, with all chiplets being internally created and applied. Interoperability with externally sourced chiplets is therefore not a concern
Silicon is the industry standard for semiconductors. However, GaN has become a more beneficial option for RF applications.

China’s biggest semiconductor manufacturer, SMIC, is rumored to complete 5nm chip development in 2025, leading to advanced chip orders from Huawei
Number of designs that are late increases. Rapidly rising complexity is the leading cause, but tools, training, and workflows need to improve.
“Historically, it’s been around 30%. Two years ago it dropped to 24% from 2023 to 2024. It dropped to 14% this time around. That’s one data point. Another is that historically we’ve seen about two-thirds of projects were behind schedule. That increased to 75% behind schedule.”
