Welcome to the OrCAD/VST demonstration disk.{ENTER}
*D0{ENTER}
{ENTER}
OrCAD/VST is a complete, affordable and easy to use{ENTER}
Verification and Simulation Tool designed to run on IBM{ENTER}
or compatible personal computers. This unique high{ENTER}
performance, low cost, logic simulator enables you to{ENTER}
increase design efficiency by allowing you to exercise and{ENTER}
debug a logic design without having to build a prototype.{ENTER}
%
*T
The logic analyzer display format makes it easy to display{ENTER}
up to 50 different channels comprising of a maximum of 250{ENTER}
different signals! With OrCAD's fast screen graphics,{ENTER}
panning is instantaneous enabling you to view the entire{ENTER}
record of the simulation trace without having to re-run the{ENTER}
simulation.{ENTER}
{ENTER}
Of course, OrCAD/VST is completely integrated with the{ENTER}
popular OrCAD/SDT schematic capture package!{ENTER}
The simulator uses the same easy to use menus and keyboard{ENTER}
macros. Your valuable time is spent productively designing{ENTER}
and testing rather trying to learn a new system!{ENTER}
%
*T

This demonstration may be stopped at any time by pressing{ENTER}
CTRL and BREAK. After the demonstration has stopped, the{ENTER}
full features of the program are at your command.{ENTER}
{ENTER}
As this is a demonstration program, saving of files and{ENTER}
hardcopy output has been disabled.{ENTER}
%
*T
OrCAD/VST has been designed to be powerful, fast and easy{ENTER}
to use. The features of the Logic Simulator program, are{ENTER}
accessed through either single character keystrokes or by{ENTER}
using the mouse. The commands and sub-commands all use{ENTER}
pop-up menus or a prompt line at the top of the screen.{ENTER}
%
*T
Commands are entered by pressing the key corresponding{ENTER}
to the first letter of the command name or by selecting{ENTER}
the command from the pop-up menu.{ENTER}
{ENTER}
When using the menu, moving the highlighted bar with the{ENTER}
cursor keys or the mouse and then pressing the ENTER key{ENTER}
executes the command. To abandon a command, press the{ENTER}
ESCAPE key.{ENTER}
%
*T
To enter commands via the mouse, the LEFT and RIGHT mouse{ENTER}
buttons will be used. The LEFT button represents the ENTER{ENTER}
key and the RIGHT button is the ESCAPE key. If the mouse{ENTER}
has three buttons the MIDDLE button has not been defined{ENTER}
and may be used as a command macro.{ENTER}
%
{ENTER}
*T
The main menu is accessed either by pressing the ENTER{ENTER}
key or the LEFT mouse button.{ENTER}
{ENTER}
The main menu allows us to Run the Simulation, Place Markers{ENTER}
for time interval measurements, and gives us access to the{ENTER}
integral pop-up editors which enable you to control stimulus{ENTER}
and tracing functions. Additionally, several commands to{ENTER}
manipulate display data can be accessed using the Trace and{ENTER}
Zoom commands.{ENTER}
%
*D4{ENTER}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{ESC}*D0{ENTER}
*T
To run a simulation, we will use the "OrCAD/VST Demo"{ENTER}
schematic which was created using the OrCAD/SDT schematic{ENTER}
capture package. This drawing is enclosed in the literature{ENTER}
package that contained this demo disk. The example consists{ENTER}
of a design that uses approximately 500 gate equivalent{ENTER}
components.{ENTER}
{ENTER}
As input, the simulator uses a flat or hierarchical netlist{ENTER}
generated by the OrCAD schematic capture package, OrCAD/SDT.{ENTER}
This netlist is automatically loaded and linked by OrCAD/VST{ENTER}
when the program is invoked. This eliminates the need for a{ENTER}
link translator which is required in many other types of{ENTER}
simulators.{ENTER}
%
*T
Before a simulation can be run, we need to define a stimulus{ENTER}
that will be used to exercise the design.{ENTER}
{ENTER}
With OrCAD/VST, the stimulus is defined very easily using{ENTER}
the EDIT STIMULUS command. This powerful editor enables you{ENTER}
to define or modify the clock period and duty cycle of the{ENTER}
applied stimulus.{ENTER}
%
*D4{ENTER}{ENTER}{D}{D}{D}{D}{ENTER}{D}{ENTER}*D0{ENTER}
*W
The stimulus editor is also used to provide clock pulses or forced logic{ENTER}
levels to other inputs in the design. Inputs such as VCC, GND, VSS, CLR,{ENTER}
PRESET, or anything else, may be programmed to have an external stimulus{ENTER}
applied.{ENTER}
%
*W
After you have created a stimulus from within the EDIT STIMULUS{ENTER}
command, the stimulus that you defined may be saved as a file using the{ENTER}
Write subcommand. Likewise, the Read subcommand enables you to load a{ENTER}
previously saved stimulus file.{ENTER}
%
*W
For our demonstration, a partial stimulus file has already been created.{ENTER}
So, we will Read the file and then "Add" the last stimulus for our{ENTER}
astable clock.{ENTER}
%
*D8{ENTER}{ENTER}{D}{D}{D}{D}{D}{D}{ENTER}DEMO2{ENTER}{ENTER}*D0{ENTER}
*W
When we execute the ADD command, a new stimulus record is created and we{ENTER}
are placed into the definition portion of the editor. OrCAD/VST can find{ENTER}
any signal name or device pin number by entering it just as it appears on{ENTER}
the schematic.{ENTER}
%
*W
As demonstrated, we shall add a stimulus called "LOAD" and program{ENTER}
our clock pulse to have a period of 3200 and a duty cycle of 3%.{ENTER}
%
*D12{ENTER}{ENTER}{ENTER}{D}{ENTER}{ENTER}LOAD{ENTER}{D}{ENTER}{D}{ENTER}{D}
{ENTER}{ENTER}3175{ENTER}{ENTER}{ENTER}{ENTER}3275{ENTER}{D}{ENTER}{ENTER}{ENTER}
6375{ENTER}{D}{D}{D}{D}{D}{ENTER}3175{ENTER}*D0{ENTER}
*W
As you can see, we have added a signal which starts as a 1, then at time{ENTER}
3175 goes to a 0 for 100 time units before returning to a 1. At time 6375{ENTER}
a jump to 3175 is performed. This forms a clock with a period of 3200{ENTER}
time units, which is low for 100 units and high for 3100.{ENTER}
%
*W
Other EDIT STIMULUS subcommands include: Set, which enables you to{ENTER}
define a stimulus in either Absolute or Relative time formats. Edit,{ENTER}
is used to edit the detail specification of the highlighted item.{ENTER}
Also, the format of a test vector file can be defined within the Test{ENTER}
Vector Editor.{ENTER}
%
*W
After the stimulus inputs are defined, we can execute the Return{ENTER}
subcommand to take us back to the main Stimulus Editor level.{ENTER}
%
*D8{ENTER}{ENTER}{D}{D}{D}{ENTER}*D0{ENTER}
*W
Now, we will execute the "Use" subcommand which automatically compiles the{ENTER}
data into a format usable by the Stimulus Generator. In addition, if{ENTER}
there are any errors in the definition, they are detected and displayed to{ENTER}
the screen.{ENTER}
%
*D8{ENTER}{ENTER}{D}{D}{D}{D}{D}{D}{D}{D}{D}{ENTER}*D0{ENTER}
*W
The final step before we can run our simulation, is to use the trace{ENTER}
editor to define the signals that are to be traced and displayed on the{ENTER}
screen. We will enter the trace editor by executing the TRACE command{ENTER}
from the main command level.{ENTER}
%
*D8{ENTER}{ENTER}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{ENTER}*D0{ENTER}
*W
The TRACE subcommand menu is now displayed on the screen.{ENTER}
%
*W
Tracing signals performs the same function as connecting a logic{ENTER}
analyzer to your design. If the trace function is like a logic{ENTER}
analyzer and the stimulus function is similar to a waveform generator{ENTER}
... then why can't we breadboard our digital design on the computer?{ENTER}
%
*W
That's exactly what we will do with OrCAD/VST. By selecting the Trace{ENTER}
Edit subcommand, we can select the signals that we want to trace and{ENTER}
display on the screen.{ENTER}
%
*D8{ENTER}{D}{D}{D}{D}{ENTER}*D0{ENTER}
*W
Like the Stimulus Editor, we can load previously saved files into the{ENTER}
trace editor with the Read subcommand. In this demonstration, we will{ENTER}
use the file which was loaded at the start of our demonstration.{ENTER}
%
*W
The main display of the Trace Editor contains 4 pieces of information{ENTER}
about each trace item. The "Display Name" is the name that appears on the{ENTER}
screen or on hardcopy. "Type" tells us if the item is a signal or what{ENTER}
type of bus is being displayed.{ENTER}
%
*W
"Trace" and "Display" tells us if tracing and/or displaying of the signal{ENTER}
is enabled. This enables you to trace a signal and have the option to{ENTER}
display it on the screen. If you think that displaying the signal might{ENTER}
be required at some time, you can trace it and display it later on.{ENTER}
%
*W
Enabling the trace, displaying, changing the type of bus, are commands{ENTER}
that we found are frequently executed. So, OrCAD decided to make these{ENTER}
commands easy to change from the main trace editor level. By moving the{ENTER}
cursor over Type, Trace, or Display, the command options will appear at{ENTER}
the top of the screen on the prompt line.{ENTER}
%
*W
With the cursor over the "Display Name" column, let's add a new item to{ENTER}
be traced and displayed on the screen. The "LOAD" signal that we entered{ENTER}
in the Stimulus Editor is a good example. With the Insert subcommand,{ENTER}
let's enter the new trace, LOAD, above the "U1 QA" display name.{ENTER}
{ENTER}
%
*D10{ENTER}{D}{D}{D}{ENTER}{D}{D}{D}{D}{ENTER}*D0{ENTER}
*W
This detailed portion of the Trace Editor enables you to specify the{ENTER}
Hierarchy and Signal Name the same way we did in the Stimulus Editor. If{ENTER}
a bus type is specified, up to 16 signals can be specified. Now, let's{ENTER}
label the "Display Name" LOAD SR and specify the "Signal Name" as LOAD.{ENTER}
%
*D10{ENTER}{ENTER}{ENTER}LOAD SR{ENTER}{D}{D}{D}{D}{D}{ENTER}{ENTER}LOAD{ENTER}
*D0{ENTER}
*W
The Signal Name, LOAD, is the exact signal name taken from our sample{ENTER}
schematic printout. If the signal you want to trace does not have a Signal{ENTER}
Name, OrCAD/VST enables you to select any signal by entering the desired{ENTER}
reference designator and pin number from your schematic.{ENTER}
%
*W
For example, instead of entering LOAD for the Signal Name, you could have{ENTER}
entered ".U7-1" instead. The ".U7" refers to the components reference{ENTER}
designator and "-1" refers to the device pin number. This information is{ENTER}
obtained from your schematic.{ENTER}
%
*W
When you have entered all of the trace data, you select the Return{ENTER}
subcommand to return you back to the main level of the Trace Editor. By{ENTER}
executing the "Use" subcommand, the trace data is automatically compiled{ENTER}
and is displayed on the screen.{ENTER}
%
*D8{ENTER}{ENTER}{D}{D}{ENTER}{ENTER}{D}{D}{D}{D}{D}{D}{D}{D}{ENTER}*D0{ENTER}
*W
Now, you can see the trace names that you specified in the Trace Editor{ENTER}
displayed on the left side of the screen. Also shown, are the trace{ENTER}
times which are displayed along the bottom of the display.{ENTER}
%
*W
Before we start our simulation, we want to specify our simulator to{ENTER}
sample the trace at specific time units. For this demo, we will change{ENTER}
our VIEW to 50. This is done within the TRACE command at the "Change{ENTER}
View" subcommand. In effect, we have told our simulator to sample the{ENTER}
trace every 50 nano seconds.{ENTER}
%
*D8{ENTER}{ENTER}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{ENTER}{ENTER}50{ENTER}*D0{ENTER}
*W
So, let's run the simulation !{ENTER}
%
*W
We enter the Simulation Length to be 24000 and press the return key.{ENTER}
%
*D6{ENTER}{ENTER}{D}{D}{D}{D}{D}{D}{D}{D}{D}{D}{ENTER}24000{ENTER}*D0{ENTER}
*W
Wasn't that fast! From the time the signal traces were displayed on{ENTER}
the screen, until now, we have just completed a simulation of our{ENTER}
500 gate design!{ENTER}
%
*W
Notice, that when trace data is displayed on the screen, a vertical{ENTER}
cursor line and arrow appears. This cursor can be moved with the mouse{ENTER}
or cursor keys. Additionally, the arrow can move up and down along the{ENTER}
cursor line.{ENTER}
%

*W
When the arrow is moved along the cursor and placed below a traced signal,{ENTER}
the logic value of the signal or bus is displayed at the "Value" prompt in{ENTER}
the lower right portion of the screen. Watch the "Value" change as we{ENTER}
move the arrow.{ENTER}
%

*W
Also displayed at the lower left and center of the screen is the "SysTime"{ENTER}
and "Cursor" values. "SysTime" indicates present time of the simulator{ENTER}
engine, while "Cursor" indicates the current position of the cursor.{ENTER}
%
*W
When auto panning is enabled, with the SET command, a horizontal pan{ENTER}
will occur when the cursor is moved beyond the left or right border.{ENTER}

To pan vertically, the <PgUp> and <PgDn> keys can be used to pan through{ENTER}
as many as 50 traces which you may have.{ENTER}
%
*D6{ENTER}{PGDN}{D}{D}{D}{D}{D}{D}{D}{U}{U}{U}{U}{U}{U}{U}{PGUP}*D0{ENTER}

In addition, several of the ZOOM sub-commands enable you to control how{ENTER}
the panning is initiated. Such as beginning and ending at the cursor,{ENTER}
or to pan to different pages.{ENTER}

PLACE MARKER command as follows.{ENTER}
%
*D6{ENTER}{ENTER}{D}{D}{D}{D}{D}{D}{D}{D}{ENTER}{R}{6}*D0{ENTER}

By enabling Multiple Markers with the SET command, you may place up to{ENTER}
three different markers with OrCAD/VST. This makes timing analysis even{ENTER}
easier!{ENTER}
