Describes Standard Delay Format (SDF) an existing OVI standard for the representation and interpretation of timing data for use at any stage of the electronic design process. It serve as a complete specification of the Standard Delay Format (SDF). It contains: - Detailed information on how SDF is used in the design process. - Detailed semantic descriptions of all SDF constructs. - The formal syntax. - Examples.

The Standard Delay Format (SDF)is an existing OVI standard for the representation and interpretation of timing data for use at any stage of the electronic design process.The ASCII data in the SDF le is represented in a tool and language independent way and includes path delays,timing constraint values,inter-connect delays and high level technology parameters. This standard is published with a double logo IEC-IEEE. standard.
