Book Synopsis Parallel Algorithms for Time and Frequency Domain Circuit Simulation by : Wei Dong

Available in PDF, EPUB and Kindle. Book excerpt: As a most critical form of pre-silicon verification, transistor-level circuit simulation is an indispensable step before committing to an expensive manufacturing process. However, considering the nature of circuit simulation, it can be computationally expensive, especially for ever-larger transistor circuits with more complex device models. Therefore, it is becoming increasingly desirable to accelerate circuit simulation. On the other hand, the emergence of multi-core machines offers a promising solution to circuit simulation besides the known application of distributed-memory clustered computing platforms, which provides abundant hardware computing resources. This research addresses the limitations of traditional serial circuit simulations and proposes new techniques for both time-domain and frequency-domain parallel circuit simulations. For time-domain simulation, this dissertation presents a parallel transient simulation methodology. This new approach, called WavePipe, exploits coarse-grained application-level parallelism by simultaneously computing circuit solutions at multiple adjacent time points in a way resembling hardware pipelining. There are two embodiments in WavePipe: backward and forward pipelining schemes. While the former creates independent computing tasks that contribute to a larger future time step, the latter performs predictive computing along the forward direction. Unlike existing relaxation methods, WavePipe facilitates parallel circuit simulation without jeopardizing convergence and accuracy. As a coarse-grained parallel approach, it requires low parallel programming effort, furthermore it creates new avenues to have a full utilization of increasingly parallel hardware by going beyond conventional finer grained parallel device model evaluation and matrix solutions. This dissertation also exploits the recently developed explicit telescopic projective integration method for efficient parallel transient circuit simulation by addressing the stability limitation of explicit numerical integration. The new method allows the effective time step controlled by accuracy requirement instead of stability limitation. Therefore, it not only leads to noticeable efficiency improvement, but also lends itself to straightforward parallelization due to its explicit nature. For frequency-domain simulation, this dissertation presents a parallel harmonic balance approach, applicable to the steady-state and envelope-following analyses of both driven and autonomous circuits. The new approach is centered on a naturally-parallelizable preconditioning technique that speeds up the core computation in harmonic balance based analysis. The proposed method facilitates parallel computing via the use of domain knowledge and simplifies parallel programming compared with fine-grained strategies. As a result, favorable runtime speedups are achieved.

Book excerpt: Circuit simulation tools (e.g., SPICE) have become invaluable in the development and design of electronic circuits. However, they have been pushed to their performance limits in addressing circuit design challenges that come from the technology drivers of smaller feature scales and higher integration. Improving the performance of circuit simulation tools through exploiting new opportunities in widely-available multi-processor architectures is a logical next step. Unfortunately, not all traditional simulation applications are inherently parallel, and quickly adapting mature application codes (even codes designed to parallel applications) to new parallel paradigms can be prohibitively difficult. In general, performance is influenced by many choices: hardware platform, runtime environment, languages and compilers used, algorithm choice and implementation, and more. In this complicated environment, the use of mini-applications small self-contained proxies for real applications is an excellent approach for rapidly exploring the parameter space of all these choices. In this report we present a multi-core performance study of Xyce, a transistor-level circuit simulation tool, and describe the future development of a mini-application for circuit simulation.

Download or read book Parallel and Distributed Multi-algorithm Circuit Simulation written by Ruicheng Dai and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the proliferation of parallel computing, parallel computer-aided design (CAD) has received significant research interests. Transient transistor-level circuit simulation plays an important role in digital/analog circuit design and verification. Increased VLSI design complexity has made circuit simulation an ever growing bottleneck, making parallel processing an appealing solution for addressing this challenge. In this thesis, we propose and develop a parallel and distributed multi-algorithm approach to leverage the power of multi-core computer clusters for speeding up transistor-level circuit simulation. The targeted multi-algorithm approach provides a natural paradigm for exploiting parallelism for circuit simulation. Parallel circuit simulation is facilitated through the exploration of algorithm diversity where multiple simulation algorithms collaboratively work on a single simulation task. To utilize computer clusters comprising of multi-core processors, each algorithm is executed on a separate node with sufficient system resource such as processing power, memory and I/O bandwidth. We propose two communication schemes, namely master-slave and peer-to-peer schemes, to allow for inter-algorithm communication. Compared with the shared-memory based multi-algorithm implementation, the proposed simulation approach alleviates cache/memory contention as a result of multi-algorithm execution and provides further runtime speedups.

Book Synopsis Partitioning Algorithms for Parallel Circuit Simulation by : David Ching-Kai Yeh
Download or read book Partitioning Algorithms for Parallel Circuit Simulation written by David Ching-Kai Yeh and published by . This book was released on 1990 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Circuit simulation is an indispensable tool in the design and analysis of Very Large Scale Integrated (VLSI) circuits. The most widely used circuit simulators rely on direct methods and offer the most accurate, reliable, and technology-independent means of simulating integrated circuits. The simulation process is inherently very computation intensive and, hence, can require a significant portion of the computational resources available for the development of VLSI circuits. With the use of multiprocessor computers becoming more widespread, there exists an opportunity to speed up the simulation by partitioning the circuit so that the computation may be spread among the processors. To accomplish this, the circuit is partitioned into subcircuits using a node tearing method. If the circuit matrix is ordered subcircuit by subcircuit followed by the tearing nodes, then the matrix takes a bordered-block-diagonal form and the LU-factorization of the diagonal blocks may take place in parallel. This thesis defines the important objectives for this partitioning task and presents two algorithms that may be used to meet the partitioning goals. The first algorithm is an iterative improvement algorithm and the second is a network flow algorithm. Partitioning results and speedups are given for a variety of circuits.
