在大多数情况下,这些操作符就像它们听起来的那样:s_until指定一个属性必须为真,直到另一个属性(必须出现)为真,s_eventually指定某个表达式必须最终为真。 这些运算符上的s_前缀代表strong,表示在无限跟踪中,指定的条件必须在某一点发生。(你可以省略s_前缀以获得这些操作符的“弱”版本,这意味着永远不会达到条件...
线性时态逻辑（LTL）操作符用于构造活动属性，如s_until与s_eventually用于指定条件必须在某个点发生。反序列属性用于检查某些条件永远不会发生，为验证提供额外维度。断言的隐式多线程特性允许多个实例同时进行，这在描述多个行为重叠时尤为重要。然而，应谨慎使用频繁触发的断言，以避免影响性能。综上所述，...
