    • Embodiments relate to validating logical statements in code for domain specific languages. An aspect includes parsing logical statements and annotating constraint type logical statements with specific constraint annotations from the logical grammar of the domain specific language. A non-contradiction graph is built using specific constraint annotations constrained to represent cases satisfying the logical statements and is solved to find a case that satisfies the logical statement or prove that no such case exists, thus locating a contradiction. The non-contradiction graph is negated to form a non-tautology graph constrained to represent cases violating the logical statements and the non-tautology graph is solved to find a case that violates the logical statement or prove that no such case exists, thus locating a tautology. A report is provided regarding at least one case satisfying the logical statement and at least one case violating the logical statement whereby the logical statement is validated.
    • 实施例涉及在域特定语言的代码中验证逻辑语句。 一个方面包括从域特定语言的逻辑语法中分析逻辑语句和注释具有特定约束注释的约束类型逻辑语句。 使用受限于表示满足逻辑语句的情况的特定约束注释构建非矛盾图,并且被解决以找到满足逻辑语句或证明不存在这种情况的情况,从而找出矛盾。 非矛盾图被否定以形成被限制为表示违反逻辑语句的情况的非重言式图,并且解决非重言式图以找到违反逻辑语句或证明不存在这种情况的情况,从而定位 重言式 提供了关于满足逻辑语句的至少一个案例和至少一个违反逻辑语句从而逻辑语句被验证的情况的报告。
