Reactive synthesis supports designers by automatically constructing correct hardware from declarative specifications. Synthesis algorithms usually compute a strategy, and then construct a circuit that implements it. In this work, we study SAT- and QBF-based methods for the second step, i.e., computing circuits from strategies. This includes methods based on QBF-certification, interpolation, and computational learning. We present optimizations, efficient implementations, and experimental results for synthesis from safety specifications, where we outperform BDDs both regarding execution time and circuit size.
响应式合成通过根据声明性规范自动构造正确的硬件来支持设计人员。综合算法通常计算一个策略,然后构建一个电路来实现它。在这项工作中,我们研究了第二步基于SAT和qbf的方法,即从策略计算电路。这包括基于qbf认证、插值和计算学习的方法。我们提出了从安全规范合成的优化、高效实现和实验结果,其中我们在执行时间和电路尺寸方面都优于bdd。

The vast quantity of data generated and captured every day has led to a pressing need for tools and processes to organize, analyze and interrelate this data. Automated reasoning and optimization tools with inherent support for data could enable advancements in a variety of contexts, from data-backed decision making to data-intensive scientific research. To this end, we introduce a decidable logic aimed at database analysis. Our logic extends quantifier-free Linear Integer Arithmetic with operators from Relational Algebra, like selection and cross product. We provide a scalable decision procedure that is based on the BC(T) architecture for ILP Modulo Theories. Our decision procedure makes use of database techniques. We also experimentally evaluate our approach, and discuss potential applications.
每天产生和捕获的大量数据导致迫切需要工具和流程来组织、分析和相互关联这些数据。具有固有数据支持的自动推理和优化工具可以在各种环境中实现进步,从数据支持的决策制定到数据密集型的科学研究。为此,我们引入了一种针对数据库分析的可决定逻辑。我们的逻辑扩展了无量词的线性整数算术,使用关系代数中的运算符,如选择和叉积。我们为ILP模理论提供了一个基于BC(T)体系结构的可扩展决策过程。我们的决策过程使用了数据库技术。我们还通过实验评估了我们的方法,并讨论了潜在的应用。
