Abstract

We propose a hybrid approach to RTL property checking that combines ATPG and ILP techniques. A special ATPG engine is designed for Boolean logic in our solver. And we use an ILP tool to solve the word-level arithmetic operator. This method is more unified and efficient than those using pure bit-level tools (such as grasp, chaff etc) or pure word-level tools (such as omega, CPLEX etc). The experiments on some public benchmarks and special circuit demonstrate the big advantage in time consumption of our approach
基于ATPG和ILP的RTL特性检测技术
我们提出了一种结合了ATPG和ILP技术的RTL属性检查的混合方法。在我们的求解器中,为布尔逻辑设计了一个特殊的ATPG引擎。并利用ILP工具求解字级算术运算符。这种方法比使用纯位级工具(如grasp、chaff等)或纯字级工具(如omega、CPLEX等)的方法更加统一和高效。在一些公共基准和特殊电路上的实验表明,该方法在时间消耗上有很大的优势
