As process technology, scales, the wire width and spacing become smaller, while wire thickness is proportionately higher. This results in increasing capacitive coupling between neighboring wires, which increases wire propagation delay and crosstalk of neighboring the wires. More importantly, coupled noise or crosstalk can affect the functionality of noise sensitive receivers. Thus, for noise sensitive datapath and control blocks, shielding signals from each other has become a necessary for implementing reliable circuits. The methodology and tool described in this paper were used to reduce the design time of domino logic control blocks in the UltraSparcIII/sup TM/ microprocessor. The two blocks reported here had delays half that of their static CMOS counterparts, the same area as the static design, capacitive coupling noise of less than 5% of VDD, and were designed in record time using the tools.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

Initially, software quality metrics are reviewed together with their application to hardware description languages. Metrics relating to circuit implementations are then discussed, such as device and testing costs, reliability, etc. A set of metrics are then proposed and evaluated for a range of VHDL specifications and the circuits resulting from logic synthesis. Initial results indicate that there is a strong correlation between specification and circuit metrics, so that their ratio may be used as a measure of design quality. Further work is proposed in order to validate the measure over a larger number of examples.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

Three levels of modeling are exploited: high-level Decision Diagrams (DD) for module test planning and system constraints generation, low-level Boolean differential equations for fault constraints generation, and medium-level Binary DDs for local test pattern generation for modules under the derived set of constraints. The proposed method of generating fault constraints the first time allows us to handle faults which increase the number of states in sequential circuits. Combining the high-level efficiency of solving complex deterministic search problems and medium-level accuracy of fault \"transportation\" analysis with low-level exact fault activation allows us to reach high efficiency in test generation, and high test quality on the other hand. Experimental results compared to the known test generators are provided for demonstrating the high efficiency of test generation achieved by the proposed approach.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

Progress in microelectronic technology is extremely fast and it is outstripping the system designers' abilities to make use of the created opportunities. The complexity and quality of the microelectronics-based systems as well as their design and production cost and time tend to be more limited by the design methods and tools than by the microelectronic technology. Substantial improvement can only be achieved through development and application of a new generation of more suitable design paradigms, methods and tools. In this paper, some new opportunities and difficulties related to the system-on-a-chip technology are overviewed, the nature of the complex system design problems is analyzed and an appropriate quality-driven system design methodology is proposed and discussed. Some important implications of the modern quality concepts for design modeling, design exploration techniques and tools, design decision making, design reuse and design validation are also discussed.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

Removal of conditions causing the equivalence in response exhibited by such faults is necessary, if fault diagnosis quality is to be improved. As Design for-Testability (DFT) methodology aims to deliver a degree of fault diagnosis substantially greater than that obtainable testing unassisted by on-chip test specific hardware, designing a DFT scheme with minimal fault equivalence is an issue to be addressed. Presented is a set of simple and inexpensive tests, applied pre-simulation, for identifying catastrophic resistive component faults that cause numerical equivalent d.c. test model responses. Using a biquadratic notch filter modified with a novel DFT scheme, we demonstrate that equivalent fault information is a useful initial measure for assessing the potential increase in fault diagnosis quality obtainable with a DFT scheme.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.
