DIRECTIONS TO USE COMPARATORS ORCAD CAPTURE LIBRARY
******************************************************************
The COMPARATORS Orcad Capture Library archive contains the following files

1. COMPARATORS.olb file, which is the symbol library file containing Orcad Capture
   symbols of all the devices in the library.

2. Orcad Capture/PSpice A/D compatible spice subcircuit files for all the devices in the symbol library. 
   For each device there will be a separate subcircuit file named after the device part number
   and with a .lib extension.

3. This README.txt file.

HOW TO USE SYMBOLS AND SUBCIRCUIT FILES IN ORCAD CAPTURE/PSPICE A/D ENVIRONMENT.
********************************************************************************   

1. Save the Symbol file and the subcircuit files to any convenient location.

2. COMPARATORS.olb symbol library file is like any other Orcad Capture library 
   file which can be edited by opening it in Orcad Capture from menu File->Open->Library.      
  
3. Symbols in the library can be used to draw circuit schematic in Orcad Capture environment. 
   To use symbols in the symbol library use menu Place->Part. Use the Add Library button in the 
   Place Part dialog box. Browse and open the COMPARATORS.olb file from where
   it has been stored. All the devices in the library will be listed in the parts list. Select 
   the device to place it into the schematic.

4. Before running the Pspice A/D simulation, .lib subcircuit files of the devices used from the 
   COMPARATORS symbol library should be included in the simulation profile of the 
   design. For including the subcircuit files use menu PSpice->Edit Simulation Profile. In the 
   simulation setting dialog box choose Configuration Files section. Select the library category, 
   browse for the subcircuit files, click Add to Design and Apply. Normal procedure for simulation 
   can be now followed for simulating the design. For more details refer to the Orcad Capture or 
   Pspice A/D manuals.
