left click with your mouse to position the BJT in your schematic window
click <esc> to stop placing the part
11) Create the intermediate schematic shown below by adding TWO Vsrc parts from the library source.
Note parts can be repositioned by dragging them. See table on right for helpful shortcut keys

Connecting Parts
After placing the parts you may wish to connect them using wires (also called nets).
12) Use hotkey w OR select the Place wire icon from the toolbar on the r.h.s. of the screen (see below)
a) Click your mouse at the starting position of your wire
b) Move (do not drag) your mouse to the location where you want a bend. Click your mouse. This
will create a bend (you may repeat this step for multiple bends)
c) Move (do not drag) your mouse to the end location and click again.
d) Click <esc> key to stop drawing wires.
Place part
Place wire
Place net alias
Click - to start
Click – to bend
Click – to end
13) Draw wires as shown below
14) Naming wires: It is much easier to maintain a design if you name the wires (nets) on your diagram.
a) From the tool bar on the rhs (see below) click the place net alias icon, OR from the top toolbar: Place>net alias
b) Type the name of the net in the menu that follows
c) With your mouse select the net that you wish to name
d) Click <esc> to end the place net alias command
Note wires that have the same name are considered to be connected. You can use this feature
to create less cluttered more readable schematics.
e) Name the wires on your schematic as shown
To simulate a schematic you must have a ground. Ground can be defined by using a ground part
or by naming nets with the number ZERO
Place net
alias ion
This is the
number
ZERO !!
Modifying Properties
15) Double click the value of the resistor (1K) and change it to be 2.5K, click <OK> to close the window.
16) Double click the DC value of the voltage source (DC=) and change it to be 5, click <OK> to close the window.
Your schematic is now complete
17) Save your schematic - ---From the main menu: File->Save
