Structured and tuned array generation (STAG) for high-performance random logic

Abstract

Regularly structured design techniques can combat complexity on a variety of fronts. We present the Structured and Tuned Array Generation (STAG) design methodology, which provides a complete design solution from logic to layout for regularly structured circuits. The STAG circuit tuning constraints are a key component of the methodology. The tuning contraints first guide a SPICE-level tuner to a violation free region in the design space. Secondly, the tuning methodology provides flexibility for targeting a variety of design contraints and objectives. Design examples illustrate STAG's ability for fast turnaround time as well as for high performance and timing critical random logic. Copyright 2007 ACM.
