摘要

本文展示了如何在SAT求解器中处理位向量上的所有不同约束(adc)。它还包含了将该技术应用于有界模型检查中对简单路径约束进行编码的令人鼓舞的实验结果。最后，我们提出了一种新的压缩CNF中位向量上的等式和不等式的编码方法。

Consistency Checking of All Different Constraints over Bit-Vectors within a SAT Solver

This paper shows how all different constraints (ADCs) over bit-vectors can be handled within a SAT solver. It also contains encouraging experimental results in applying this technique to encode simple path constraints in bounded model checking. Finally, we present a new compact encoding of equalities and inequalities over bit-vectors in CNF.
