Standard Delay Format
Standard Delay Format (SDF) is an IEEE standard for the representation and interpretation of timing data for use at any stage of an electronic design process. It finds wide applicability in design flows, and forms an efficient bridge between dynamic timing verification and static timing analysis.
It has usually two sections: one for interconnect delays and the other for cell delays.
SDF format can be used for back-annotation as well as forward-annotation.
