LT Spice Library models
Design engineers and product development engineers typically start with schematic design and do simulations to optimize their designs. This inductor SPICE model can help engineers model inductors in their circuit.
CWS provides this LT Spice simulation model so that design engineers can select the most optimal inductive component for the circuit design.

LT Spice – how it works

• Analog devices provide the LT Spice Schematic and simulation platform (www.Analog.com) for easy circuit modeling. The LT SPICE platform has become an industry standard for many other simulation software and tools. This platform saves time, cost, and effort by minimizing re-spins of actual circuit hardware.
• Many design engineers and educational institutions use LT Spice to design and simulate the circuits by importing the library components from various manufacturers.
  Various components manufacturers such as inductors, transformers, coils, capacitors, resistors, and other active and passive components have made SPICE Library of their components that users can download and link within their LT Spice circuit design to do the simulation.
• For more details on the LT Spice, please visit http://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html
• We suggest that designers download the latest version from the above link. Analog devises Inc. updates its software regularly to improve its design and simulation tools.

 How to use the LT Spice is provided in the above link from Analog Devices.

Installation of COILWS Model Library 

=====================================================================

Please make sure that LTspice software is not running and follow the below steps

1. The zipped model library folder of the CWS_Spice_Library_CMM for LTspice comprises the following two folders: 
2. - Sub: This folder contains the ASCII data file (C_CMM.lib) that represents the actual library
   • Copy and paste this file to C:Users"USER NAME"DocumentsLTspiceXVIIlibSub .
3. - Sym: This contains the subfolder "CWS Comp.Chokes" which includes the symbol data files for the graphics information required by the graphic user interface.
   • Copy and Paste this file to C: Users"USER NAME"DocumentsLTspiceXVIIlibsym .
4. On the next start of LTspiceXVII, open a New Schematic, Click on the Component Library (or press on F2), and find the [CWS Comp.Chokes] folder appears in the LTspice Component library.
5. Double Click on [CWS Comp.Chokes] folder and choose your Part number.

 NOTE:

• PLEASE DON'T RENAME ANY OF THE ABOVE 2 FOLDERS.
• ' "USER NAME" - this varies for each individual user's laptop/PC 
• In the DEMO circuit attached below - in case the LTSpice shows any error/missing component - please add the 'DEMO Circuit Supplement Library file in the LTSpice folder as explained in the "Readme-Demo-Ckt-Simulation."
