摘要

提出了一种基于ROBDD表示的多级逻辑综合方法。这种方法使得处理非常复杂的电路成为可能,而这些电路是经典的分解算法无法合成的。使用了两个重要的算法。前者从一个ROBDD生成一个多级表达式。后者从表示不完全指定的布尔函数的两个ROBDD构建最小的ROBDD。这种方法是在逻辑合成软件logic中实现的,该软件是作为ALLIANCE CAD软件包的一部分开发的。

Multilevel logic synthesis of very high complexity circuits
This paper presents an approach based on ROBDD representation for multilevel logic synthesis. This approach makes it possible to handle very high complexity circuits that cannot be synthesized by the classical factorization algorithms. Two important algorithms are used. The former generates a multilevel expression from an ROBDD. The latter builds a minimal ROBDD from the two ROBDDs representing an incompletely specified Boolean function. This approach is implemented in the logic synthesis software LOGIC developed as part of the ALLIANCE CAD package.<>
