This paper describes a diagnosis technique for locating design errors in circuit implementations which do not match their functional specification. The method efficiently propagates mismatched patterns from erroneous outputs backward into the network and calculates circuit regions which most likely contain the error(s). In contrast to previous approaches,(More)
In an effort to fully exploit CMOS performance, custom design techniques are used extensively in commercial microprocessor design. However, given the complexity of current generation processors and the necessity for manual designer intervention throughout the design process, proving design correctness is a major concern. In this paper we discuss Verity, a(More)
As devices and lines shrink into the deep submicron range, the propagation delay of signals can be effectively improved by repowering the signals using intermediate buffers placed within the routing trees. Almost no existing timing driven floorplanning and placement approaches consider the option of buffer insertion. As such, they may exclude solutions,(More)

Recent trends in high performance microprocessor design suggest that complex gigahertz processors based on deep-submicron CMOS technologies will be practical in the near future. It is also certain that integration complexity will result in ever-increasing demand for interconnection connectivity and bandwidths. Front-end chip planning, back-end interconnect(More)
Several issues associated with multichip module (MCM) system design are discussed. An early analysis tool for evaluating the tradeoffs between a design and packaging technology is presented. A case study of a possible design point suggested by combining different package elements being used in MCMs settings is included. The case study indicates that the(More)
