EDIF Definition
Electronic Design Interchange Format. An industry-standard format for the transmission of design data.
You can generate an EFIF Input (.edf) File from a schematic design or from a VHDL or Verilog HDL design processed with an industry-standard synthesis tool, and then import the file into the Quartus® Prime software as an EFIF Input (.edf) File. The Quartus® Prime software supports EDIF Input Files that contain functions from the library of parameterized modules (LPM).
