Chiplets and the Early Adopter’s Dilemma


Early adopters of a new technology often face a serious dilemma. On one hand, moving early means exploiting the most aggressive new technology available. But on the other hand, making early technology decisions can lock a product line into a path that will later become uncompetitive—either a single-vendor solution that can’t guarantee continuity of supply, or a roadmap that can’t shift an... » read more

Developing Workflows To Streamline System-Level Design


Experts At The Table: One of the big challenges facing EDA companies is explaining to customers what's possible, how to streamline their designs, and what can be accomplished at what level of risk. Semiconductor Engineering sat down to talk about how relationships are fundamentally changing between EDA companies and their customers Michal Siwinski, chief marketing officer at Arteris; Chris Muet... » read more

Enabling Efficient Multi-Die Design Implementation and IP Integration


Many industry trends are driving chip developers to consider multi-die designs using advanced 2.5D and 3D technologies. Such designs enable incorporating heterogeneous and homogeneous dies in a single package, increasing density while reducing signal propagation times. However, multi-die designs introduce new challenges that must be addressed by all relevant electronic design automation (EDA) a... » read more
