This set of two disks contain OrCAD's Verification and Simulation Tools 
(VST) 386+, the major component of Digital Simulation Tools 386+. Digital
Simulation Tools also includes the program PLD Modeling Tools (MOD), which 
is installed from an accompanying disk.

Use OrCAD's INSTALL program to install this disk set. The INSTALL program is
contained on a separate disk, or, if you have installed other OrCAD tools, 
INSTALL may be loaded on your system already.

Installation instructions can be found in the "OrCAD Installation & Technical 
Support Guide."

If you have used an older version of OrCAD's Digital Simulation Tools, 
please note the following:

1.  Digital Simulation Tools 386+ version 1.10 and greater can print.
    Use the Hardcopy command in the simulator to output simulation
    results using the printer driver you select in the Configure Simulation
    Tools option of the Simulate button in the ESP Design Environment.
    If you are using DOS 5 and the GRAPHICS.COM program you can also print
    the simulation image displayed on your video screen by pressing the <Print
    Screen> button key on your keyboard.

2.  The model library for Digital Simulation Tools 386+ contains the 
    following new models:

        Series 74  ALS family (ALS.DSF)

            29809   857

        Series 74   AS family (AS.DSF)

            857

        Series 74 AHCT family (AHCT.DSF)

            592

        Series 74   LS family (LS.DSF)

            671     672     697     698     699

        Series 74    S family (S.DSF)

            226     381

3.  The model library for Digital Simulation Tools 386+ contains the following
    updated models:

        Series 74    F family (F.DSF)

            381

4.  Digital Simulation Tools 386+ uses slightly different formats for the 
    stimulus (.STM) and trace (.TRC) files than the older version did.  
    Digital Simulation Tools 386+ automatically converts your old files to
    the new format.  

    If you need to use Digital Simulation Tools 386+ files with an older 
    version of the simulator, please follow this process:

       1. Decompile the 386+ .STM and .TRC files to text format using 
       "Decompile Simulation Specification."  The resulting stimulus and 
       trace files have the extensions .AST and .ATR

       2. After decompiling the files to text format, compile the ASCII 
       text trace and stimulus files with the Release IV version of 
       Digital Simulation Tools using "Compile Simulation Specification."

       This process is also described in Appendix F of the Digital Simulation
       Tools 386+ Reference Guide.
