Symbol Generation Options Form

Library Name specifies the library for the generated cellview.

Cell Name specifies the cell name for the generated cellview.

View Name specifies the view name for the generated cellview.

Pin Specifications lets you change pin order or move pins to different sides of the symbol.

Left Pins creates pins for the left side of the symbol.

Right Pins creates pins for the right side of the symbol.

Top Pins creates pins for the top of the symbol.

Bottom Pins creates pins for the bottom of the symbol.

Attributes

List opens a corresponding attributes form that you can use to change the pin direction and the pin graphic attributes.

Load/Save displays options you can use to specify which TSG template file the system references when creating a symbol automatically.

Load consists of a Load button, a cyclic field, and a text field. The cyclic field lists the

TSG template file keywords. The text field changes when you select a keyword. When you click the Load button, the system loads the file displayed in the text field.

Save (TSG File) specifies a path for the file you want to save.

Load Template Data From Symbol specifies a file that contains the TSG template information.

Library Name specifies the library name of the cellview that contains the TSG template information.

Cell Name specifies the cell name of the cellview that contains the TSG template information.

View Name specifies the view name of the cellview that contains the TSG template information.

Edit Attributes expands the form to display the symbol attributes options.

Pin Spacing specifies the spacing between pins.

Stub Length specifies a length for the line that represents the pin wire.

Height increases the minimum height value for the generated symbol. When set to 0

(default), TSG uses pin and label data to determine the minimum height value for the symbol.

Width increases the minimum width value for the generated symbol. When set to 0 (default), TSG uses pin and label data to determine the minimum width value for the symbol.

Pin Connector contains a list of pin connector shapes.

Origin contains a list of possible origin locations for the generated symbol.

Reverse Pin Order creates a symbol with the pins in reverse order.

Edit Labels expands the form to display the label options.

Label contains a list of the current labels.

Name specifies a label that you want to add to theLabel cyclic field.

Label Choice contains a list of label types.

Apply To contains a list of the pin types to which you can apply the label.

Label Type contains a list of the types you can assign to the label.

Orientation specifies the orientation of the label.

Font Height specifies the height of the label text.

Justification specifies the location of the label.

Font Style contains a list of the fonts you can apply to the label.

isOverbar is only a display option. You use this option to specify whether the software displays an overbar over a label in the design window. When disabled (default), the software displays underscore characters ( _ ) in the label as part of the label text string. When enabled, the software interprets underscore characters ( _ ) in the label as toggle switches that control where overbars begin and end.

To avoid confusion when text actually contains underscore characters, Cadence recommends that you disable this display option. It is provided only for backward compatibility.

Location specifies where on the symbol to place the label.

Add adds the pin name you specify in the Name field to the list under theLabel cyclic field.

Delete removes the pin name you specify in the Name field from the list under theLabel cyclic field.

Modify applies the changes you specify in the form to the specified label.

Edit Properties expands the form to display the property options.

Property contains a list of the current properties.

Name specifies a property that you want to add to theProperty List cyclic field.

Value specifies a value for the property you specify in theName field.

Apply To contains a list of the pin types to which you can apply the property.

Property Type contains a list of the types you can assign to the property.

Orientation specifies the orientation of the property in respect to the instance.

Font Height specifies the height of the property text.

Justification specifies the location of the property.

Font Style contains a list of the fonts you can apply to the property.

isOverbar is only a display option. Use this option to specify whether the software displays an overbar over a label in the design window. When disabled (default), the software displays underscore characters ( _ ) in the label as part of the label text string. When enabled, the software interprets underscore characters ( _ ) in the label as toggle switches that control where overbars begin and end.
