The Bonn
& IBM Workshop on Processor Physical Design Efficiency is a collaborative
effort between the University of Bonn and the Electronic Design Automation
(EDA) organization at IBM. The workshop will consist of multiple tracks
covering the most critical ongoing work in support of the 3nm high
performance chips for the IBM mainframes. There will also be focus groups to
fascilitate in person collaboration, engagement and brainstorming to help
drive the most innovative set of EDA tools in the industry. |
