.LPE File Extension

Layout Parameter Extrat netlist

Question: What is an LPE File?

Have you found, downloaded or received an LPE file, but don't know which software program is required to open it?

Before attempting to open an LPE file, you'll need to determine what kind of file you are dealing with and whether it is even possible to open or view the file format.

Answer: Files which are given the .LPE extension are known as Layout Parameter Extrat netlist files, however other file types may also use this extension. If you are aware of any additional file formats that use the LPE extension, please let us know.

How to open a LPE file:

The best way to open an LPE file is to simply double-click it and let the default assoisated application open the file. If you are unable to open the file this way, it may be because you do not have the correct application associated with the extension to view or edit the LPE file.

This file format was added to our database by a visitor to this site, but no additional information was provided. We have yet to investigate this file type further, or there was not enough information available at the time to report accurately on the format.

Please check back soon for more information as we are constantly updating our file descriptions based on search frequency.

Tip: Try to open the LPE file using a text-editor such as Notepad, as many file types contain simply contain unformatted plain-text and can viewed correctly using this method.

This is a format for SPICE netlists that are derived from a GDSII or other physical transistor layout format. Generally it is used in verification of integrated circuit layouts in CAD tools.

This is used for LVS (layout versus schematic). LVS takes the physical (layout) version of the design and extracts an LVS netlist. It also takes a schematic representation (either CAD drawings or HDL such as Verilog netlist) and writes a spice netlist then compares the physical LPE spice netlist versus the one obtained from the original schematic version.

This ensures that the circuits a design describes in this design are in fact what is represented in the final GDSII file. The GDSII is then sent for manufacture at say IBM, TSMC, SMIC or other IC foundary.
