BEAM

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES		 l, w, angle
DESIGN TIPS
  • values for l and w end with the letter "u" denoting microns,
  • angle can be either "0" - terminals of type "m" at the left side of the symbol,
    or "90"- terminals of type "m" at the bottom of the symbol,

 

COMB_1

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES		 finger_width, finger_length,
angle,
overlap, gap, fingers,
truss_width_a, truss_width_b,
wing_length_a, wing_length_b
DESIGN TIPS
  • All of them except "angle" require to be ended with the letter "u" denoting microns,
  • Angle can be either "0" - terminals of type "a" at the left side of the symbol,
    or "90"- terminals of type "a" at the bottom of the symbol,
  • The rotor (right side) has a number of fingers equal to the value of "fingers" property, while the stator (left side) has 1 finger more

COMB_2

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES		 finger_width, finger_length,
angle,
overlap, gap, fingers,
truss_width_a, truss_width_b,
wing_length_a, wing_length_b
DESIGN TIPS
  • all of them except "angle" require to be ended with the letter "u" denoting microns,
  • angle can be either "0" - terminals of type "a" at the left side of the symbol,
    or "90"- terminals of type "a" at the bottom of the symbol,
  • the rotor (left side) has a number of fingers equal to the value of "fingers" property, while the stator (right side) has 1 finger more

PLATE

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES		 unitl, unitw, joint_offset,
percentage_holes
angle, unitnum_x, unitnum_y
DESIGN TIPS
  • the plate consists of the plate units which length is unitl and width is unitw, repeated horizontally unitnum_x times and vertically unitnum_y times.
  • An area of holes in each unit is defined by percentage_holes property (i.e. a plate with 50% of holes area holds the percentage_holes property value of 0.5)

ANCHOR

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES		 l, w
DESIGN TIPS
  • values for l and w end with the letter "u" denoting microns;
  • l denotes a direction perpendicular to a side where anchor is connected to another element.
  • w denotes a direction parallel to a side where anchor is connected to another element.

LAYOUT_ORIGIN

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES
DESIGN TIPS defines (0,0) layout co-ordinates and technology library for layout generation therefore it has to be taken from NODAS_poly library.,

COMB_DIFF_1

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES		 finger_width_a, finger_width_b, finger_length,
angle,
overlap, gap, fingers,
truss_width_a, truss_width_b,
wing_length_a, wing_length_b
DESIGN TIPS
  • all of them except "angle" require to be ended with the letter "u" denoting microns,
  • angle can be either "0" - terminals of type "a" at the left side of the symbol,
    or "90"- terminals of type "a" at the bottom of the symbol,
  • the rotor (right side) has a number of fingers equal to the value of "fingers" property, while the stator (left side) has 1 finger more
  • the fingers of stator are differential fingers.

COMB_DIFF_2

SYMBOL
PROPERTY
WINDOW

 
REQUIRED
PROPERTIES		 finger_width_a, finger_width_b, finger_length,
angle,
overlap, gap, fingers,
truss_width_a, truss_width_b,
wing_length_a, wing_length_b
DESIGN TIPS
  • all of them except "angle" require to be ended with the letter "u" denoting microns,
  • angle can be either "0" - terminals of type "a" at the left side of the symbol,
    or "90"- terminals of type "a" at the bottom of the symbol,
  • the rotor (left side) has a number of fingers equal to the value of "fingers" property, while the stator (right side) has 1 finger more
  • the fingers of stator are differential fingers.
