静态时序分析（英语：Static Timing Analysis, STA），或称静态时序验证，是电子工程中，对数字电路的时序进行计算、预计的工作流程，该流程不需要通过输入激励的方式进行仿真。

传统上，人们常常将工作时钟频率作为高性能的集成电路的特性之一。为了测试电路在指定速率下运行的能力，人们需要在设计过程中测量电路在不同工作阶段的延迟。此外，在不同的设计阶段（例如逻辑综合、布局、布线以及一些后续阶段）需要对时间优化进程内部进行延迟计算（Delay calculation）。尽管可以通过严格的SPICE电路仿真来进行此类时间测量，但是这种方法在实用中耗费大量时间。静态时序分析在电路时序快速、准确的测量中扮演了重要角色。静态时序分析能够更快速地完成任务，是因为它使用了简化的模型，而且它有限地考虑了信号之间的逻辑互动。静态时序分析在最近几十年中，成为了相关设计领域中的主要技术方法。

Static timing analysis (STA) is a simulation method of computing the expected timing of a digital circuit without requiring a simulation of the full circuit.

High-performance integrated circuits have traditionally been characterized by the clock frequency at which they operate. Gauging the ability of a circuit to operate at the specified speed requires an ability to measure, during the design process, its delay at numerous steps. Moreover, delay calculation must be incorporated into the inner loop of timing optimizers at various phases of design, such as logic synthesis, layout (placement and routing), and in in-place optimizations performed late in the design cycle. While such timing measurements can theoretically be performed using a rigorous circuit simulation, such an approach is liable to be too slow to be practical. Static timing analysis plays a vital role in facilitating the fast and reasonably accurate measurement of circuit timing. The speedup comes from the use of simplified timing models and by mostly ignoring logical interactions in circuits. It has become a mainstay of design over the last few decades.
