The shortest-path problem is a fundamental computer science problem with applications in diverse areas such as transportation, robotics, network routing, and VLSI design. The problem is to find paths of minimum weight between pairs of nodes in edge-weighted graphs, where the weight of a path p is defined as the sum of the weights of […]

With the advances of very large scale integration (VLSI) technology, the feature size has been shrinking steadily together with the increase in the design complexity of logic circuits. As a result, the efforts taken for designing, testing, and debugging digital systems have increased tremendously. Although the electronic design automation (EDA) algorithms have been studied extensively […]

In this paper, we propose a new parallel statistical analysis method for large analog circuits using determinant decision diagram (DDD) based graph technique based on GPU platforms. DDD-based symbolic analysis technique enables exact symbolic analysis of vary large analog circuits. But we show that DDD-based graph analysis is very amenable for massively threaded based parallel […]

Prevailing VLSI trends point to a growing gap between the scaling of on-chip processing throughput and off-chip memory bandwidth. An efficient use of memory bandwidth must become a first-class design consideration in order to fully utilize the processing capability of highly concurrent processing platforms like FPGAs. In this paper, we present key aspects of this […]

This paper presents a study on a high-performance design for a block cipher algorithm implemented on modern many-core graphics processing units (GPUs). The recent emergence of VLSI technology makes it feasible to fabricate multiple processing cores on a single chip and enables general-purpose computation on a GPU (GPGPU). The GPU strategy offers significant performance improvements […]

Graph-based symbolic technique is a viable tool for calculating the behavior or the characterization of an analog circuit. Traditional symbolic analysis tools typically are used to calculate the behavior or the characteristic of a circuit in terms of symbolic parameters (Gielen et al., 1994). The introduction of determinant decision diagrams based symbolic analysis technique allows […]

Sparse linear systems are found in many common scientific and engineering problems. In VLSI CAD tools, performing DC circuit analysis can create large, sparse systems represented by huge matrices. Solving such systems can take orders of magnitude of time to compute. Many attempts have been made to parallelize algorithms to solve these matrices. Graphics cards, […]

In this article, we developed a massively parallel gate-level logical simulator to address the ever-increasing computing demand for VLSI verification. To the best of the authors’ knowledge, this work is the first one to leverage the power of modern GPUs to successfully unleash the massive parallelism of a conservative discrete event-driven algorithm, CMB algorithm. A […]

Stochastic computing performs operations using streams of bits that represent probability values instead of deterministic values. An important benefit of stochastic computing is that it can tolerate a large number of failures in a noisy system. Additionally, for the VLSI implementation of a sophisticated algorithm, a stochastic implementation can consume much less hardware with lower […]

In this paper, we propose a new parallel analysis method for large analog circuits using determinant decision diagram (DDD) based graph technique. DDD-based symbolic analysis technique enables exact symbolic analysis of vary large analog circuits. Once the circuit small-signal characteristics are presented by DDDs, evaluation of DDDs will give exact numerical values. In this paper, […]

Graphics processing units (GPU) of today include hundreds of multi-threaded, multicore processors and a complex, high-bandwidth memory architecture, making them a good alternative to speed up general-purpose parallel computation where large data quantities are processed with same functions. Some successful applications of GPU computation have also been introduced in the field of circuit simulation. The […]

Logic simulation of a VLSI chip is a computationally intensive process. There exists an urgent need to map functional validation algorithms onto parallel architectures to aid hardware designers in meeting time-to-market constraints. In this paper, we propose three novel methods for logic simulation of combinational circuits on GPGPUs. Initial experiments run on two methods using […]
