WebAug 1, 2009 · Standard Delay Format (SDF) 1.0, 2.0, 3.0, 4.0 SPEF: Standard Parasitic Exchange Format (SPEF) is an IEEE standard for representing parasitic data of wires in a chip in ASCII format. SPEF is most popular specification for parasitic exchange between different tools of EDA domain during any phase of design. WebSPEF (Standard Parasitic Exchange Format) is documented in chapter 9 of IEEE 1481-1999. Several methods of describing parasitics are documented, but we are discussing only few important one.

WebStandard Parasitic Exchange Format (SPEF) OpenTimer reads parasitics of a net set as a resistive-capacitive (RC) network. Each RC network is described in a Standard Parasitic Exchange Format (SPEF) file. If the connection does not have parasitics, then the delay is zero and the output slew is euqal to the input slew. WebSep 6, 2016 · This information is captured in a Switching Activity Interchange Format (SAIF) file. The method for doing this is explained in Section 5.b. THIS IS A MANUAL STEP. The PAD_Flow.pl script is run to create final power and delay information for the design using the SAIF and SPEF files from the previous steps.

Standard Parasitic Exchange Format (SPEF) is an IEEE standard for representing parasitic data of wires in a chip in ASCII format.
