The aim of the methodology is to increase design and product quality. At system level, emphasis is given to architecture generation, reconfiguration and quality assessment. Quality metrics and criteria, focused on design and test issues, are used for the purpose. At physical level, a Defect-Oriented Test (DOT) approach and test reuse are the basis of the methodology to estimate test effectiveness, or defects coverage. Tools which implement the methodology are presented. Results are shown for a public domain PIC processor, used as a SOC embedded core.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

In this paper we propose a Low Power Automatic Test Pattern Generator (LPATPG) with peak power. reduction. The technique can be used during on-line testing of large circuits requiring low power consumption. The LPATPG can be implemented using linear cellular automata (CA) with appropriate external weighting logic. While the average power is reduced by finding the optimal signal activities (probabilities of signal switching) at the primary inputs, the peak power is reduced by restricting the number of active primary inputs. Results on ISCAS benchmark circuits show that while achieving high fault coverage, average power reduction up to 90%, peak power reduction up to 37% and energy reduction up to 93% can be achieved (compared to equi-probable random pattern generator by linear cellular automata), and the ratio of the number of high power vectors (vectors violating the power limit) in the LPATPG sequence to the number of high power vectors in the equi-probable random sequence can be as low as 0.44%.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

In this paper, we address the issues related to the gate bridge, which is serious in sub-quarter micron technology, and the wide range of contact CD (Critical Dimension) variation. We present the efficient gate CD control method by introducing the critical area correction. In addition, the contact CD variation is reduced under the target CD range due to the combination of the contact biasing and the process calibration. The correction time and output data volume are drastically reduced by the hierarchical data manipulation using a DRC (Design Rule Check) tool, which basically exploits the characteristics of the design layers in ASICs. The newly proposed incremental on-line violation filtering method also reduces the correction cycle time significantly.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

Delay skew was shown to generate common-mode currents at a rate of four times that of slew rate skew. Radiated EMI levels were shown to follow increasing common-mode currents. Attention to delay skew imbalance should be an important design consideration at the chip level, the transmission line level and at the load in order to produce high speed differential circuits with low emission characteristics. While models using identified waveforms predict common-mode waveform harmonics that include only odd harmonics, measurements with real devices indicate the presence of all harmonics due to waveform asymmetries, such as dirty cycle distortion and rise/fall time asymmetries.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

The design of the chip at functional-block level is directly captured by the simulator, allowing the assessment of the chip layout impact on the system performance due to the elevated operational temperature. The heat generation for each block is obtained by running the circuit-level electrical simulation separately on individual functional units. The thermal diffusion equation is then solved based on the actual structure of the chip including substrate and interconnect/insulating layers. Different thermal conductivity can be specified for each material layer. The effect of package on chip temperature distribution is modeled using thermally resistive layers as the boundary between the simulated structure and surrounding environment. Proper adjustment of the boundary thermal resistance results in the correct range of simulated temperature distribution as compared to the measured data. Both physics and implementation for the thermal simulation are described. The code is applied to the analysis of a realistic design of a CPU chip made of SOI technology with up to six metal interconnect layers. A comprehensive review of the simulation results is presented.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.

In this paper, the space- and time-oriented compaction techniques are considered together. First, the space-oriented data compaction technique is analyzed. We present a scheme, which can compress the data of k-output circuit into 1-bit signature stream with zero-aliasing and zero-performance-degradation for single stuck-line faults. Based on the investigation of the space's odd-sensitized and space's even-sensitized faults of the circuits under test, we discuss the compact methods of space's odd sensitization and space's even sensitization test responses, respectively. The graph coloring is adopted to decrease space compactor overhead. The coloring complexity is greatly decreased owing to only painting the output notes with respect to the space's even-sensitized faults. Next, we take into account the time-oriented data compaction scheme. We use the property that a test vector detects multiple faults in the time's even sensitization response compaction. In the time-oriented compaction approach developed in this paper, an s-bit long data stream can be compressed to an r-bit signature with zero-aliasing, where s/spl Gt/r. Experimental results are presented to demonstrate the effectiveness of the proposed space- and time-oriented compaction techniques.","PeriodicalId":113766,"journal":{"name":"Proceedings IEEE 2000 First International Symposium on Quality Electronic Design (Cat.
