BUILDING CAD PROTOTYPING TOOL FOR EMERGING NANOSCALE FABRICS

The design of CAD tools for nanofabrics involves new challenges not encountered with conventional CMOS technology. In this paper, we describe the design of a prototyping CAD tool targeting design automation of applications on a wide range of nanofabrics. Our proposal is based on a variety of models that capture as well as isolate the differences between the fabrics. This tool supports the design flow from behavioral description to final layout. It integrates fault-tolerant techniques and fabric-related density transformations with more conventional design automation techniques. After an overview of common requirements, physical models, and associated techniques, a case study in the context of NASIC fabrics is used to illustrate some of the concepts.
