This disk contains the OrCAD ESP Design Environment (ESP) software.

INSTALLING ESP

1. Insert the disk labeled "ESP Disk 1" in your computer's floppy disk drive.

2. At the DOS prompt, enter the name of the drive the disk is in. For example,
   if you placed the installation disk in drive A, type A: and press <Enter>.

3. Type INSTALL and press <Enter>.

From this point on, INSTALL prompts you to enter the information it needs to
install the software on your system.

If you are upgrading an existing installation and have designs that need to 
be updated, INSTALL tells you it is going to use FIXDAT to update your local 
configuration screens. Press any key if you use the directory structure 
recommended by OrCAD. Press <Esc> if you have a different directory 
structure, and run FIXDAT from the command line.


USING FIXDAT

FIXDAT transfers configuration information from older versions of ESP to 
newer versions, eliminating the need to reconfigure tool sets, local 
configurations, and the on/off status of Transfer tools after updating the 
software. FIXDAT updates the ORCADESP.DAT files in your design directories.

FIXDAT takes two arguments:  

*  The path and filename of the old ORCADESP.DAT file to update. In this 
   discussion, the file to update is called oldDATfile.  

*  The path and filename of the new ORCADESP.DAT file. In this discussion, 
   this is called newDATfile.  

This is how FIXDAT works:  

1. FIXDAT reads in newDATfile followed by oldDATfile.  

2. FIXDAT compares the two files and finds buttons in newDATfile that have 
   the same name as buttons in oldDATfile. If it finds a match, FIXDAT copies 
   the local configuration setting for that button from oldDATfile to 
   newDATfile. When FIXDAT is through with the comparison, you have a new 
   newDATfile with as many of oldDATfile's local configuration settings as 
   apply.   

3. FIXDAT replaces oldDATfile with the updated newDATfile.  

If newDATfile has buttons that don't exist in oldDATfile, the local 
configuration settings for the new buttons are set to OrCAD's defaults.  

NOTE: If you do not run FIXDAT when you install your update, the ORCADESP.DAT 
file is copied to a TEMPLATE directory on the hard disk drive you specified 
as the drive on which to install the OrCAD software. 

Syntax:

   FIXDAT [oldDATfile newDATfile] [switches]  

Updates oldDATfile so that it has all of the buttons found in newDATfile. 
The settings in oldDATfile remain unchanged.  

/A  Reads the ORCADPROJ environment variable to find the TEMPLATE design 
    directory. The ORCADESP.DAT files in ALL of the design directories are 
    updated to the version of the ORCADESP.DAT file in the TEMPLATE design. 
    oldDATfile and newDATfile are not specified when the /A switch is used.  

/L  Reads the ORCADPROJ environment variable to find the TEMPLATE design 
    directory. The ORCADESP.DAT file in the current directory only is updated 
    to the version of the ORCADESP.DAT file in theTEMPLATE design directory. 
    oldDATfile and newDATfile are not specified when the /L switch is used.  

/U  Does the transfer even if oldDATfile and newDATfile are already the same 
    version. The /U switch can be used in conjunction with the /L switch or 
    /A switch. If so, oldDATfile and newDATfile are not specified.  

NOTE: FIXDAT reports an error if either newDATfile or oldDATfile does not 
exist.  

Examples:

The next sections describe how to use FIXDAT to:  

* Update all your ORCADESP.DAT files  

* Update TEMPLATE's data file and data files in selected designs  

* Update one ORCADESP.DAT file  


Update all your ORCADESP.DAT files

If your directory structure is standard and you want to update all your
data files, follow these steps:

1. Change to the TEMPLATE design and enter this command at the DOS prompt:

      C:\ORCAD\TEMPLATE> fixdat orcadesp.dat orcadesp.421  

   ORCADESP.DAT is the data file with all your current configuration
   settings. ORCADESP.421 is the data file with the latest updates to the
   design environment, and is saved in the TEMPLATE directory only when
   FIXDAT is run from the command line (not during installation). This 
   command updates your data file to the new version without losing your 
   configuration settings.

2. To update the data file in each design, enter this command from anywhere 
   in the directory structure:

      C:\> fixdat /A

3. Delete ORCADESP.421 from your TEMPLATE design to prevent copying it to new
   designs. (If you allow INSTALL to automatically update the ORCADESP.DAT 
   files, INSTALL automatically deletes ORCADESP.410 for you.)


Update TEMPLATE's data file and data files in selected designs  

1. Change to the TEMPLATE design and enter this command at the DOS prompt:

      C:\ORCAD\TEMPLATE> fixdat orcadesp.dat orcadesp.421  

   ORCADESP.DAT is the data file with all your current configuration 
   settings. ORCADESP.421 is the data file with the latest updates to the
   design environment, and is saved in the TEMPLATE directory only when
   FIXDAT is run from the command line (not during installation.  This 
   command updates TEMPLATE's data file to the new version without losing 
   your configuration settings.  

2. Change to the design containing the ORCADESP.DAT file you want to update.

3. Enter this command at the DOS prompt:  

      C:\ORCAD\YOURDESN> fixdat /L  

4. Repeat steps 2 and 3 for each design you need to update.  

5. Delete ORCADESP.421 from your TEMPLATE design to prevent copying it to new
   designs.  


Update one ORCADESP.DAT file  

To update a data file in a specific design without updating any other data  
files, follow these steps:  

1. Copy the new data file ORCADESP.421 to a floppy disk. In this example, the
   floppy disk is in drive A.  

2. Delete ORCADESP.410 from your TEMPLATE design.  

3. Enter this line:  

      C:\> fixdat \orcad\yourdesn\orcadesp.dat a:\orcadesp.421  

   FIXDAT updates ORCADESP.DAT in the YOURDESN directory to match the version
   of ORCADESP.421 in the A drive.  


ADDITIONAL TECHNICAL INFORMATION

1. Before you can run OrCAD executables from outside the ESP environment, 
   your AUTOEXEC batch file must include a line to tell the OrCAD executables 
   which driver to load. For example, if you use a VGA driver AUTOEXEC.BAT 
   should include the following line:

      SET ORCADDD=C:\ORCADESP\DRV\VGA640.DRV

   This assumes that you installed the default directories on your C drive.

2. Any special video drivers you create with the GENDRIVE utility are not 
   displayed in the configuration scroll boxes. To use your custom driver, 
   delete the driver name selected and enter the name of the custom driver.
