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.

The methscript language has transformed the methodology development process. Floor-planning and physical implementation flows now have the design teams actively engaged in developing release-able
methodologies.

Methscript – a designer oriented language
Syntax-lite, compact language (positional parameters and simple delimiters)
Simple defaults (e.g. methodology step name used as default applications script)
Short cuts (e.g., one methscript line can generate N-way parallel flow for all modules)
Many single line scope commands “continue on error” parsing
Legacy XML methodology interface
File validity checking at parse time All subflows could be contained in one
methscript file, resulting in multiple XML files
Back annotation of scripts integrated into Guide user interface
Historical runtime data retained in Guide session for use in next run

Design Profiling - smart feedback - design health check example
Automatic collection, analysis, and reporting saves each designer ~ 4 hours per week managing their results and summarizing for team lead/management.

Design Profiling - smart feedback – milestone prediction example
Design teams use design profiling to extrapolate how fast a design will close for next milestone.
Visualization reports can help identify the spots where designers are iterating.
