© 2013 IBM Corporation A Smarter Design Environment 3 Abstract The chip design environment needs to grow smarter and more intuitive in order to leverage the evolving capabilities of design automation tools / flows and the increasing complexity of technologies beyond 32 nm. This infrastructure intelligence embodies the creation of symbiotic relationships between the software developers applications and the designers exploitation of them. In these relationships, design teams are integral to the development and optimization of the infrastructure. This presentation outlines a set of infrastructure applications / processes that our Design and Technology infrastructure group, working in collaboration with chip design teams, has developed to address these demands for internal and customer projects. These include a cognitive designer interface, an intuitive methodology language/parser, a predictive, “on the fly” and historical analytics system, and an elastic model/tool suite environment. A high level overview of each item, use cases, and benefits is presented as well as how the design engineers were incorporated into their development.

Floor-planning and physical implementation flows now have the design teams actively engaged in developing release-able methodologies.
