This chapter provides a basic tutorial on the Standard Delay Format (SDF) as it applies to component modeling. The overall file format is described. The capabilities of SDF and its syntax are explored. SDF is a convenient way to annotate timing values into a simulation. The standard delay format is based on IEEE … WebAn SDF construct can have multiple matches, in which case each matching specify statement is updated with the SDF timing value. SDF constructs are matched to Verilog constructs as follows: IOPATH is matched to specify path delays or primitives: SDF. Verilog.
