并行计算在电子线路分析中的应用

Application of Parallel Computation in the Analysis of Electronic Circuits

在第三代电路模拟技术的基础上，应用撕裂法在电子线路的分析中进行了并行计算。通过对部分支路撕裂而将电路转化为一系列独立的子电路，使电路方程具有加边的分块对角结构。应用Ｇａｕｓｓ－Ｓｅｉｄｅｌ－Ｎｅｗｔｏｎ多重循环迭代及松驰迭代等，实现了多级并行计算。结果表明，计算速度明显提高。

Parallel computation has been applied to the analysis of electronic circuits. In this technique a circuit is partitioned into a series of subcircuits by tearing some branches,and the ma- trix has bordered block-diagonal structure. The multistage parallel computation is accomplished by using the methods of Gauss-Seidel-Newton multicycling iteration and relaxation iteration.
