1.0) Introduction

     This file describes how to setup and run the classroom versions of
     PSPICE and PROBE.  You are welcome to make as many copies as you
     find convenient of all the files on the Classroom Version PSpice
     diskette.  You may run the classroom version of PSpice on as
     many different PC's as you wish.

     This diskette came from a desire to respond to many requests we
     have received for using PSPICE for teaching electronics courses.
     Since the commercial version of PSPICE and PROBE are $950 and $450,
     respectively, cost was a problem when trying to provide the program
     to an entire class. From discussions we have had with professors it
     appeared that for many situations a restriction on the circuit size of
     10 transistors was acceptable.  That restriction allows us to offer
     this version of PSPICE to all electronics professors in the United
     States at no charge.  We hope that it will be useful to you.

2.0) System Configuration

     PSPICE will run on an IBM PC, XT, or AT with 512kbytes of memory.
     The floating-point co-processor (8087 or 80287) is optional.  If present,
     the program will run at full speed.  Otherwise it will run 5-15 times
     slower.  Either the monochrome or color display may be used.  Any
     printer may be used.

     PSPICE runs under MSDOS 2.0+ and requires the system to have been
     booted with a CONFIG.SYS file which contains the statement:

          FILES=10

     It is also recommended that the CONFIG.SYS file contain the statement:

          BUFFERS=10

     Such a CONFIG.SYS file is included on Diskette 1.

     For PROBE the only difference is that the floating-point processor
     is not optional.  It is required.

3.0) Running PSPICE

     PSPICE is 2 programs: PSPICE1.EXE (on Diskette 1) and PSPICE2.EXE (on
     Diskette 2).  For systems with a fixed disk, simply copy the all the
     files into a directory and then start PSPICE with the command:

          PSPICE input-file output-file

     For PC systems, you must run PSPICE1.EXE and then PSPICE2.EXE.  You can
     either use one drive for the program diskettes, switching them between
     PSPICE1.EXE and PSPICE2.EXE, or use 2 drives, putting one program
     diskette in each.  In the 1st case, the input, output, and scratch
     files would go on the 2nd drive.  In the 2nd case, the files would go
     on the drive which has diskette PSPICE1.  For both cases regarding the PC,
     the input and output files are specified when PSPICE1.EXE is run:

          PSPICE1 input-file output-file

     For all the above cases, the input-file and output-file may have
     pathnames.  The program files, too, can be on any directory specified
     by a previous DOS PATH command.  Note that PSPICE1.EXE does not call
     or overlay or chain to PSPICE2.EXE.  PSPICE2.EXE must be explicitly
     run.  See PSPICE.BAT for an example.

     The input file must be specified, but its extension need not be.  Its
     extension defaults to .CIR.  The output file is optional, its name
     defaults to the input file's name and its extension defaults to .OUT.
     If the input file is not specified you will be prompted for it.  The
     output file may be a device, such as the printer.  This command would
     run EXAMPLE1 to the printer:

          PSPICE EXAMPLE1 PRN

     assuming that you have the standard DOS reserved names.

     PSPICE1.EXE creates 2 temporary files, PSPICEA.TMP and PSPICEB.TMP,
     which are passed on to PSPICE2.EXE.  PSPICE2.EXE creates 2 more
     temporary files, T3.TMP and T4.TMP.  At normal program termination of
     PSPICE2.EXE all 4 temporary files are deleted.  For a long run their
     combined size will be about 40kbytes.

4.0) Format of the Input and Output Files

     The input and output files are ordinary text files and follow the
     same rules as those for the UC Berkeley Spice program, version 2G.6,
     with these omissions:

       1) There is no distortion (.DISTO) analysis.  We recommend using the
          .TRAN and .FOUR to calculate harmonic distortion.  This method
          correctly accounts for clipping, which .DISTO does not.
       2) There is no .ALTER command.

     In addition, numerous enhancements to the Berkeley Spice have been
     added including GaAs MESFET devices, group delay, and the ability to
     reference device libraries in other files.  For more details on these
     and other PSPICE enhancements, the PSpice User's Guide may be
     purchased from MicroSim for $40.00.  Unfortunately, the user's guide
     is not available in machine-readable format.  It is typeset and
     contains both formulas and diagrams.

5.0) Restrictions for the classroom version

     This version of PSpice will run in 512kbytes.  It will run with or
     without the floating-point co-processor.  All the features of the
     production PSpice as of May 1986 are included except that the circuit
     size is restricted to a maximum of about 10 transistors.  The production
     version of PSpice comes with a library of models for about 100 standard
     devices (diodes, bipolar transistors such as the 2N2222, power MOSFET's,
     opamps, and comparators).  This diskette includes a reduced version of
     the standard parts libraries.

6.0) Running Probe

     This diskette also contains Probe, the graphics post-processor for PSpice.
     Probe is run by adding the statement:

          .PROBE

     to the input file to PSpice.  Then, PSpice stores all the node voltages
     and device currents calculated during the simulation into a file called
     PROBE.DAT.  The presence of the PROBE.DAT file will cause Probe to be
     run automatically as soon as PSpice is finished.  In addition, once
     the PROBE.DAT file is created, Probe can be run by itself (that is,
     without re-running PSpice) by typing

          PROBE

     To run Probe the first time, we recommend adding a ".PROBE" statement
     to EXAMPLE1.CIR with a text editor and then typing:

          PSPICE EXAMPLE1

     PSpice will simulate EXAMPLE1 and create a PROBE.DAT file.  After
     PSpice is finished Probe will start up automatically.

     Probe accepts commands through a menu displayed at the bottom of the
     screen.  Most of these commands are self-explanatory.  Note that the
     Add Trace command allows you to enter arithmetic expressions of voltages
     and currents as well as the voltages and currents themselves.

     The PROBE.DEV file contains a list of the devices attached to your
     system.  The allowed devices for "Display = " are:

          Text:          Non-graphics display
          IBM:           IBM CGA (640x200 no color) adaptor
          IBMEGA:        IBM EGA (640x350 with color) adaptor
          Hercules:      Hercules graphics (720x348 no color) adaptor
          FutureNet:     DASH2 graphics (640x350 no color) adaptor

     The allowed devices for "Hard-copy = " are:

          Text:          Non-graphics printer
          Text132:       Non-graphics printer (132 columns)
          Epson:         Epson FX-80 printer

          HI             Houston Instruments DMP pen plotter
          HPLJ           Hewlett Packard LaserJet printer

     We recommend that you use "Text" first before trying out your system's
     graphic devices.  Note: this classroom version of Probe is for IBM and
     IBM-compatible PC's only.  It will not run on the Texas Instruments
     professional.

     This version of Probe requires the 8087 floating-point co-processor.
     Unlike PSpice it will not run without it.  This version of Probe has
     all the capabilities of the production Probe as of May 1986.

7.0) Device Libraries

     The classroom version of PSpice comes with models for some standard
     parts.  These are found in the files with extension ".LIB".  These
     are ascii, text files and we recommend that you print them out and
     read them, starting with the file NOM.LIB.

     Libraries may be referenced by using the statement:

          .LIB <file name>

     in the .CIR file.  See NOM.LIB for examples.  If <file name> is left
     out then it defaults to "NOM.LIB".  If any device in the .CIR
     file references a model or subcircuit that is not defined in the .CIR
     file then PSPICE will search all files referenced by .LIB statements
     and use .MODEL or .SUBCKT statements found in the library files.

     Our level of technical support for the commercial version of PSPICE is
     quite high.  Unfortunately, we cannot provide the same kind of service
     for the classroom version due to the large number of users and the fact
     that it is provided at no charge.
