采用标准-活动。 本标准中定义了标准延迟格式（SDF）。SDF是一种文本文件格式，用于表示电子系统的延迟和定时信息。虽然人机可读，但在其最常见的用途中，它将是机写和机读的，以支持时序分析和验证工具，以及其他需要延迟和时序信息的工具。本标准的主要受众是支持该格式的工具的实现者，但是有人需要了解该格式吗？s的内容会发现它很有用。

Adoption Standard - Active. The Standard Delay Format (SDF) is defined in this standard. SDF is a textual file format for representing the delay and timing information of electronic systems. While both human and machine readable, in its most common usage it will be machine written and machine read in support of timing analysis and verification tools, and of other tools requiring delay and timing information. The primary audience for this standard is the implementers of tools supporting the format, but anyone with a need to understand the format's contents will find it useful.
