1.3 Operators
1.4 Autogenerate Features

1.1 Writing

1.1.1 Go to Draw menu
1.1.2 Select Text
1.1.3 Position the mouse to desired location of the equation on the drawing panel.
1.1.4 Then click the left mouse button.
1.1.5 A textarea window will appear at the bottom point where you can type the text content.
1.1.6 Repeat steps 1 to 5 to add more equations.
1.1.7 To end writing equations, press the "Select" button under "Draw Menu" or the toolbar

1.2 Equations Formats

1.2.1 Constant: "v=const"

"v" is the name of the constant

Must be an alphanumeric string with no spaces and operators before and after
The first character must be an alphabet (A..Y or a..y)

"=" necessary equality sign for all equations
"const" any numeric value
Example: x=3
This assigns 3 as the value of x

1.2.2 Variable: "v=func"

"v" is the name of the variable

Must be an alphanumeric string with no spaces and operators before and after
The first character must be an alphabet (A..Y or a..y)

"=" necessary equality sign for all equations
"func" any logical combinations of variables, operators or constants

Must follow logical operator usage (see operators)
May be the sum of one or more terms
May be a polynomial
All variables used must be declared previously

Example: y=x^2` which will display as y=x²

This assigns the square of x as the value of y

1.2.3 Parametric Function: "v(x)=func(x)"

"v" is the name of the parametric function

Must be an alphanumeric string with no spaces and operators before and after
The first character must be an alphabet (A..Y or a..y)

"(x)" is the name of the parameter

Must be enclosed by open and close parenthesis
Inside the parenthesis, x must be an alphanumeric string with no spaces and operators before and after
More than one parameter may be declared by separating the parameters with a comma eg. (x,y,z)

"=" necessary equality sign for all equations
"func(x)" any logical combinations of variables, operators, constants and the parameter x

Must be follow logical operator usage (see operators)
May be the sum of one or more terms
May be a polynomial
All variables used must be declared previously

Example: y(x)=x^2`+5 which will display as y(x)=x²+5

This function can then be used as y(3)=3²+5 such that y(3)=11

1.2.4 Display Value: "v=?d.pppp unit"

"v" is the name of the variable to display

Must be an alphanumeric string with no spaces and operators before and after
The first character must be an alphabet (A..Y or a..y)

"=" necessary equality sign for all equations
"?" necessary question sign to request for value display
"d.pppp" optional format chars

p determines the number of decimal places
if not specified, it will display as per required to show significant values

" " space to separate the unit

May be just one single space
Marks that the succeeding alphanumeric string is a unit

"unit" any predefined unit or user defined units

Must follow logical operator usage (see operators)
Must be only one term
All elements must be predefined

Example: Assume these were defined earlier R1=700*ohms Vo=12*V Io=[Vi/R1]

Then Io=?d.ppp mA which will display as Io=d.ppp mA will become Io=?17.143 mA which will display as Io=17.143 mA after
pressing the Calculate button

1.3 Types of Operators

1.3.1 Arithmetic Operators

"+" addition example: x+3
"-" subtraction example: x-3
"/" division example: x/y or x/3
"*" multiplication example: 2*x or 3*mA
"^" exponent example: x^3` displays as x³

The end of exponent must always be succeeded by terminator "`"

Precedence:

x=3+2*4 means x=3+8 not x=5*4
x=3*4-2 means x=12-2 not x=3*2
"-" behaves likes "+" and "/" behaves like "*" in the above example

1.3.2 Format Operators

"[" if followed by "/" then "[", then indicates that the characters between "[" and "/"

should be placed on top of a divide line

"]" if preceded by "/" then "[", then indicates that the characters between "/" and "]"

should be placed below a divide line

"[","/" and "]" are used to display divisions in a multiline manner.
Equations written as y=[x+y/x-y] will display as shown below
牋牋牋牋牋_x+y
y=^{燺__________}
牋牋牋牋牋^x-y
"~" subscript operator

The subscript should be terminated by "`"

Example: V~A` will display as V_A
"{" and "}" function value operator deprecated in release 13.0

The function value operator forces the value of a function
when used as part of another equation

Example:

f(x)=x²
y={f(3)}+3 means 3²+3 = 12
release 12.0 y=f(3)+3 will mean 0+3 = 3 since f(3) has no meaning
release 13.0 y=f(3)+3 will mean 3²+3 = 12

1.3.3 Grouping Operators

"(" Open parenthesis
")" Close parenthesis
"("and ")" is use to group precedence of operations

(2+3)*4 means 5*4 not 2+12
(4-2)/(3-1) means 2/2 not 4+0.6667-1

">=" "greater than or equal" such that (2>=2) means (1) , (2>=3) means (0)

"<=" "less than or equal" such that (2<=2) means (1) , (2<=3) means (1) and (3<=2) means (0)
"==" "equals" such that (2==3) means (0) and (3==2) means (0) and (3==3) means (1)

1.3.4 Predefined Operators

1.3.5.1 Trigonometric Functions

"sin" such that sin(pi/4) means 0.707
"cos" such that cos(pi/3) means 0.5

3.6 Moving Vertices/Objects

Any vertex of a line, rectangle, ellipse, or any object
except for the behavior and text that is not yet selected
can be moved while in select mode by dragging the vertex.
When the current object is already selected, dragging at
the vertex would cause the entire object and any other selected object to moved.

3.6.2 Position the cursor to the vertex of an unselected objext, the cursor will
become a cross hair when you hit the vertex.
3.6.3 Press the left mouse button and hold it down without releasing.
This causes the object to be selected. The cursor should turn into a
drag cursor (arrow pointing upper left and lower right) At this stage
while holding the left mouse button, the position of the vertex can be moved
3.6.4 Pressing the left mouse button again would transition the cursor to MOVE
mode (arrow poiting up,down,left and right) since the object was already selected
during the previous press. At this stage the entire object and any other selected
can be moved.
3.6.5 Thus pressing the left mouse button again and again while holding it down
every press will allow you to choose whether to simply move a vertex or move the
entire object

can be set by going to the File Info And Bookmark Tabpane and press on the Spice
library path to set it. Any spice model or subcircuit placed in this directory with a .lib
extension will be used by spice to automatically search upon generation of spice netlist.
5.3.4 Go to the "File" menu.
5.3.5 Choose the "Export" button. Select "Spice Netlist" submenu
A Spice Netlist save dialog box will appear.
5.3.6 Select or type the desired file destination and press okay.
