System-on-a-chip designs will have a tremendous impact on the efficient management of design data. Time-to-market constraints require hierarchy and component re-use, while the increasing chip complexity, design sizes, and specialization of components will make geographically distributed design teams more likely. While in an ideal world the definition of interfaces would allow these distributed teams to work in parallel on their respective modules with little interaction, in reality a successful design is likely to require intensive interaction and collaboration throughout the design process. Critical to this process will be the ability to build, integrate, and test the distributed design components, which will require a scalable and efficient data caching architecture.

We are working to identify the needs and requirements for an architecture that will provide integration between heterogeneous tools and efficient support for collaborative incremental design. Areas of interest include relaxed transaction models suited towards collaborative work and intelligent, distributed caching of design data. We are combining tool usage metrics, design data characteristics, and likely interactions throughout the design process to build a representative model of EDA data interactions. This model will be used in experiments that will analyze the tradeoffs of different data management techniques in various design scenarios and resource organizations. Our research goal is to find reliable design data management and transactional semantics for large datasets in a distributed, potentially unreliable, network environment.
