WebIt gives information on the timing data extensively used in backend VLSI design flows. SDF gives information about. Path delays. Interconnect delays. Timing constraints. Tech parameters affecting delays. Cell delays. SDF file is also used in the back annotation of delays in the gate level simulations for mimicking the exact Si behavior. Q53. Design Exchange Format (DEF) is an open specification for representing physical layout of an integrated circuit in an ASCII format. It represents the netlist and circuit layout. DEF is used in conjunction with Library Exchange Format (LEF) to represent complete physical layout of an integrated circuit while it is being designed. DEF was developed by Cadence Design Systems.
