The cell name portion of a symbol cellview into which the generated symbol is stored; must be enclosed in quotation marks.
|
|
t_pinType
|
The type of pin: must be enclosed in quotation marks.
Valid Values: input, output, io
By default, all input pins are drawn on the left side of the symbol from top to bottom, all output pins are drawn on the right side of the symbol from top to bottom, and all I/O pins are drawn on top of the symbol from left to right.
To move a pin to any other side, specify the pin in the pinLocSpec construct. If a pin specified in pinLocSpec is also specified in the output or io constructs, an error message is generated.

symbolParam
|
Specifies symbol parameters. They can be included in any order without replication. They are not stored in the symbol master property list.

|
f_spacing
|
The minimum spacing between any pair of adjacent pin wires on a side, rounded to the nearest multiple of snap spacing.
|
|
f_length
|
The length of each pin wire (a pin stub), rounded to the nearest multiple of snap spacing
Default: twice the value of the wireSpacing field
|
|
f_vLength
|
The minimum length of the vertical sides, rounded to the nearest snap spacing. If the value you supply is less than the computed default, the computed default is used.
|
|
f_hLength
|
The minimum width of the horizontal sides, rounded to the nearest snap spacing. If the value you supply is less than the computed default, the computed default is used.
|
|
t_connector
|
The default pin connector graphic (each entry is mapped into a cellview that contains the graphics for the connector); must be enclosed in quotation marks.
Valid Values: square, block, circle
|
|
t_origin
|
The default placement of the symbol origin.
Valid Values: topLeftPin, bottomLeftPin, centerLeft
|
|
symbolLabels
|
Define symbol labels. If this construct is not specified, a set of default labels is generated on the symbol.
|
|
t_labelText
|
The text of the label; must be enclosed in quotation marks.
|
|
controlParam
|
Contains control parameters to define execution behavior.
This control parameter is not stored in the property list of the symbol master.
|
|
g_boolean
|
Use only when the specified symbol master already exists in the library. When set to t, TSG asks several questions interactively. When set to nil (the default), TSG assumes an existing symbol should be overwritten. It does not prompt you for permission to overwrite an existing symbol cellview.
Valid Values: t, nil
Default: nil
This control parameter is the only one that can be included in this construct and is not stored in the property list of the symbol master.
|
|
pinNumSpec
|
This construct is most often used for printed circuit board design libraries.
|
|
t_pinName
|
A pin name; must also be declared in input, output, or io.
|
|
x_pinNumber
|
A pin number.
|
|
pinLocSpec
|
Allows you to override default pin placement locations; specifies the pin location in any order without replication.
|
|
t_leftPinName
|
The names of pins to draw on the left of the symbol; must be enclosed in quotation marks. Must also be specified in the input, output, or io construct.
Other pins can be drawn on the left of the symbol. Pins specified in input are also drawn on the left of the symbol. A pin specified in input but not specified in pinLocSpec is drawn on the left before those in leftPins. A pin name in leftPins cannot be specified again in the other three subconstructs.
|
|
t_rightPinName
|
The names of pins to draw on the right of the symbol; must be enclosed in quotation marks. Must also be specified in the input, output, or io construct.
Other pins can be drawn on the right of the symbol. Pins specified in output are also drawn on the right of the symbol. A pin specified in output but not specified in pinLocSpec is drawn on the right before those in rightPins. A pin name in rightPins cannot be specified again in the other three subconstructs.
|
|
t_topPinName
|
The names of pins to draw on the top of the symbol; must be enclosed in quotation marks.
Other pins can be drawn on the top of the symbol. Pins specified in io are also drawn on the top of the symbol. A pin specified in io but not in pinLocSpec is drawn on the top before those in topPins. A pin name in topPins cannot be specified again in the other three subconstructs.
|
|
t_bottomPinName
|
The names of pins to draw on the bottom of the symbol; must be enclosed in quotation marks.
A pin name in bottomPins cannot be specified again in the other three subconstructs.
|
|
pinGraphicSpec
|
Identifies special pin graphics, such as negation bubbles and clock indicators, to be drawn with the specified pins.
|
|
t_pinGraph
|
Identifies special pin graphics, such as negation bubbles and clock indicators.
Valid Values: actHi, actLo, ieeeActLo, clock, actLoClock
Default: actHi
Each of these values must match an entry in the schConfig.il file.
|
|
pinLogicSpec
|
Using this construct is not recommended, but it remains supported for backward compatibility. The pinGraphicSpec construct is the preferred method for specifying special pin graphics.
Specifies negation indicators.
|
|
t_posPin
|
A list of pin names that indicate the positive logic type of the pins; must be enclosed in quotation marks.
|
|
t_negPin
|
A list of pin names that indicate the negative logic pin type; must be enclosed in quotation marks. Negative pins appear in the symbol as a bubble.
|
|
clockPins
|
Using this construct is not recommended, but it remains supported for backward compatibility. The pinGraphicSpec construct is the preferred method for specifying special pin graphics.
Specifies the display of clock indicators.
|
|
t_clockPin
|
A list of pin names that indicate clock pins. Any pins must also be specified in input, output, or io. Clock pins are designated by a small triangle next to the pin.
