OpenSTA is a gate level static timing verifier. As a stand-alone executable it can be used to verify the timing of a design using standard file formats. Verilog netlist; Liberty library; SDC timing constraints; SDF delay annotation; SPEF parasitics; OpenSTA uses a TCL command interpreter to read the design, specify timing constraints and print.

LPE is an acronym for Layout Parasitic Extraction The way I confirm it is to just go through the full flow of a design: schematic simulation -> DRC -> LVS -> parasitic extraction -> post-layout simulation A quick sanity check would be see if you can create a new lib attaching the tsmcN65 library tech file, then try to instantiate a schematic cell, say nmos_rf, then create a layout for it.

The SPEF provides a standard medium to pass parasitic information between EDA tools during any stage in the design process. Syntax All keywords in SPEF start with an asterisk (*), followed by all capital or underscore. e.g. `*D_NET` Keywords, identifiers, characters, and numbers are delimited by syntax characters, white_space, or newline.

May 31, 2020 by Team VLSI. SDC is a short form of “Synopsys Design Constraint”. SDC is a common format for constraining the design which is supported by almost all Synthesis, PnR and other tools. Generally, timing, power and area constraints of design are provided through the SDC file and this file has extension .sdc.

SPEF also has a syntax that allows the modeling of capacitance between different nets, so it is used by the PrimeTime SI (crosstalk) analysis tool. SPEF is smaller than SPF and DSPF because the names are mapped to integers to reduce file size. SBPF is a Synopsys binary format supported by PrimeTime. Parasitic data converted to this format.
