Standard Parasitic Exchange Format (SPEF) is an IEEE standard for representing parasitic data of wires in a chip in ASCII format. Non-ideal wires have parasitic resistance and capacitance that are captured by SPEF. These wires also have inductance that is not included in SPEF. SPEF is used for delay … See more SPEF (Standard Parasitic Extraction Format) is documented in chapter 9 of IEEE 1481-1999. Several methods of describing parasitics are documented, but we are discussing only a few important ones. See more SPEF is not the same as SPF (including DSPF and RSPF).
