The Parametric Generation (Transistor) dialog allows you to generate the shape of transistors. It is displayed by selecting Home > Generate >Parametric > Transistor on the Footprint Editor ribbon. This command is only available in 2D View mode.
Pin Shape Tab
Symbol Mark Tab
Component Area Tab
Pin Shape Tab
Allows you to specify the configuration of the pins for a transistor, as shown below.
Pin pitch W
| Value | Description |
|---|---|
| Real number equal to, or greater than 0. | Specify the pitch for a pin shape. |
Padstack Name
| Value | Description |
|---|---|
| String | Select the padstack or pad that is used for a pin shape. |
Position
Specify the pin position that is set as the origin. Select from the following options:
- Left Pin
- Center Pin
- Right Pin
Symbol Mark Tab
Allows you to generate a symbol mark for the transistor.
Generate symbol mark
| Value | Description |
|---|---|
| Selected | Allows you to generate a symbol mark. All relevant fields in the Symbol Mark tab are made available. |
| Not selected | Specifies that a symbol mark shape is not generated. All fields in the Symbol Mark tab are made unavailable. |
Shape
This setting is only made available if Generate symbol mark is selected. Specify a symbol mark shape from the following options. The dimensions shown on each image refer to the values in the Symbol mark shape settings table.
- Semicircle
- Rectangle
Symbol mark shape settings
These settings are only made available if Generate symbol mark is selected.
| Parameter | Value | Description |
|---|---|---|
| Symbol length X | Real number greater than 0. | Specify the length of the symbol mark shape in the direction of the X-axis. |
| Symbol length Y | Real number greater than 0. | Specify the length of the symbol mark shape in the direction of the Y-axis. |
| Gap D | Real number. | For a symbol mark shape, specify the distance between the center pin, and the center point of a circle that makes up a semicircle. This is done using a positive value for the upper side, and a negative value for the lower side. Specify this value if the Shape field is set to Semicircle. |
| Mark width M | Real number equal to, or greater than 0. | Specify the distance between the lower side of the rectangle for a symbol mark shape, and the horizontal line. Specify this value if the Shape field is set to Rectangle. |
Line width
This setting is only made available if Generate symbol mark is selected
| Value | Description |
|---|---|
| A real number greater than 0. | Specify the width of the line. |
Line attributes
This setting is only made available if Generate symbol mark is selected in this tab.
| Value | Description | |
|---|---|---|
| Line type | Specify the format of the line. | |
| Solid | A solid line is generated. | |
| Dash | A dashed line is generated. | |
| Dash dot | A "dash-dot" line is generated. | |
| Dash dot dot | A "dash-dot-dot" line is generated. |
Generation layer
This setting is only made available if Generate symbol mark is selected
| Value | Description |
|---|---|
| Layer name | Specify the layer on which a symbol mark shape is generated. |
Component Area Tab
Allows you to generate a component area for the transistor.
Generate Component Area
| Value | Description |
|---|---|
| Selected | Allows you to generate a component area. All fields in the Component Area tab are made available. |
| Not selected | Specifies that a component area is not generated. All fields in the Component Area tab are made unavailable. |
Length X
The following setting is only made available if Generate component area is selected.
| Value | Description |
|---|---|
| Real number greater than 0. | For a rectangular component area, this setting specifies the
X value of its dimensions. The default value is the same as Symbol length X on the Symbol
Mark tab. |
Length Y
The following setting is only made available if Generate component area is selected.
| Value | Description |
|---|---|
| Real number greater than 0. | For a rectangular component area, this setting specifies the
Y value of its dimensions. The default value is the same as Symbol length Y on the Symbol
Mark tab. |
Height (Standoff - Maximum)
The following setting is only made available if Generate component area is selected.
| Value | Description |
|---|---|
| Real number equal to, or greater than 0. | Specify the spatial height of the component area. |
Generation Layer
The following setting is only made available if Generate component area is selected.
| Value | Description |
|---|---|
| Layer name | Specify a layer from which to generate a component area. |
