Wave-pipelining: a tutorial and research survey

Wave-pipelining is a method of high-performance circuit design which implements pipelining in logic without the use of intermediate latches or registers. The combination of high-performance integrated circuit (IC) technologies, pipelined architectures, and sophisticated computer-aided design (CAD) tools has converted wave-pipelining from a theoretical oddity into a realistic, although challenging, VLSI design method. This paper presents a tutorial of the principles of wave-pipelining and a survey of wave-pipelined VLSI chips and CAD tools for the synthesis and analysis of wave-pipelined circuits     

A New Approach to Abstracting AltPSM Lithography Requirements for IC Design Domains

This paper lays the groundwork for defining the components needed to get clean alternating phase-shifting masks (altPSM) that ensure the manufacturability of subwavelength circuit designs. The authors create an abstract set of rules that can be used to advantage in various IC CAD tool domains. A new methodology and algorithm are presented that can quickly and easily integrate altPSM into existing and future tools earlier in the IC design flow. Finally, experimental results show how the methodology and algorithm is used to debug process-aware designs and make them altPSM-compliant.Pradiptya Ghosh has a M.S. (Computer and System Engg) from Rensselaer Polytechnic Institute, New York and a B.Engg (Computer Engineering) from Delhi University, India. He is currently working on physical syntesis tool for FPGA. Previously he has worked on alternating PSM methodology and developed tools for integrating it into DFM flow.

Tools for the computer-aided design of multigigahertzsuperconducting digital circuits

The realization of large integrated circuits depends upon the application of computer-aided design (CAD) tools. This paper summarizes the results of a survey of CAD tools targeting superconducting digital electronics. Five categories of tools: circuit simulators, circuit optimizers, layout tools, inductance estimators, and logic simulators are discussed in detail. Within each category, a comparison of several currently available CAD tools is presented, and a tool which has been adapted for use or developed at the University of Rochester is discussed in greater detail. In addition, tools for timing analysis as well as integrated design environments that permit the effective data interchange among various tools and support libraries of design models are discussed. Future tools for timing optimization, automated logic synthesis, and automated layout synthesis are shown to be necessary for the design of superconducting circuits at the very large scale of integration (VLSI) level of integration. Trends regarding changes in the requirements for effective CAD tools are discussed, and expected improvements to existing tools and features of new tools currently under development are presented

Computer-aided design of VLSI circuits

With the rapid evolution of integrated circuit (IC) technology to larger and more complex circuits, new approaches are needed for the design and verification of these very-large-scale integrated (VLSI) circuits. A large number of design methods are currently in use. However, the evolution of these computer aids has occurred in an ad hoc manner. In most cases, computer programs have been written to solve specific problems as they have exist and no truly integrated computer-aided desisn (CAD) systems exist for the design of IC's. A structured approach both to circuit desisn and to circuit verification, as well as the development of integrated design systems, is necessary to produce cost-effective error-free VLSI circuits. This paper presents a review of the CAD techniques which have been used in the design of IC's, as well as a number of design methods to which the application of computer aids has proven most successful. The successful application of design-aids to VLSI circuits requites an evolution from these techniques and design methods.
