A Top-Down, Constraint-Driven Design Methodology for Analog Integrated Circuits
Abstract:
A novel design methodology is presented for analog circuit design.
The methodology is aimed at reducing substantially the design cycle of
complex analog and mixed analog-digital systems while maintaining or even
improving the performance of the final design. This goal is achieved
through the use of a hierarchical approach where early verification and
constraint propagation is favored. High-level behavioral simulation is
used for immediate high-level verification of circuit performances and
used for supporting the constraint-driven layout tools. The tools
presented are a first cut at the implementation of the design methodology
advocated.
