Terminal(Pin) Properties

PartQuest Portal Subscription: Essential or Professional

When you are creating or editing a custom symbol for a PartQuest Portal part with the Symbol Creator tool, you can adjust the property values of the symbol pins.

Description

Some properties have dependencies on each other. The following table will help ensure you only select valid combinations of properties.

Property

Description

Name

Required

Defines the name of the symbol terminal(pin). This is the same name that is referenced when mapping the symbol terminal(pin) names to the footprint terminal(pin) names.

The Symbol Creator tool allows you to use duplicate terminal(pin) names, and displays the duplicate names on the resulting symbol. However, the tool assigns each duplicate terminal a hidden name with a suffix of __x, where “x” is a number starting at 0 and incrementing by 1 for each duplicate terminal(pin) name on the same symbol.

Terminal #(Pin #)

Maps the terminal(pin) names to individual footprint terminal(pin) numbers. This field is not required to create your symbol, but your part may not be ready to use with your design entry tool unless you complete this.

Inverted

Marks the terminal(pin) as inverted. The tool adds a graphic (line above terminal name) to the terminal(pin) to represent it as inverted on the generated symbol.

Direction

Defines the direction of the signal for this terminal(pin) as In, Out, or In/Out. Graphic annotations are shown for "In/Out". Use the PartQuest settings to control if graphic annotations are shown for "In" direction terminals(pins) on the right and "Out" direction terminals(pins) on the left.

Elec. Function

Defines the general function of the terminal(pin) as Signal, Ground, Power, or No-Connect.

Elec. Type

Defines whether the terminal produces or consumes an Analog or Digital signal.

Electrical Type is only valid for “Signal” terminals(pins).

Output Type

Defines the terminal as Open Collector, Open Emitter, Tristate, or Open Drain.

Output Type is valid for terminals(pins) that are defined as “Out” (Direction).

Connect. Type

Defines the signal as a Load, Source, or Terminator.

Implicit

Sets a terminal(pin) to either Yes or No. Terminals set to Yes are included on the part, but do not show on your symbol.

Power, Ground, and No-Connect terminals(pins) can be set to implicit (Yes). The implicit terminals(pins) are represented appropriately in the flow you are using.

Clock

If set to Yes, defines the terminal(pin) as a clock.

Active High1

If set to Yes, defines the terminal(pin) to be active on a high level.

Active Low1

If set to Yes, defines the terminal(pin) to be active on a low level.

Hysteresis1

If set to Yes, defines the terminal(pin) to be hysteresis.

Enable1

If set to Yes, defines the terminal(pin) function to be an enable.

Amplifier1

If set to Yes, defines the terminal(pin) function to amplify the signal.

Passive Pull-up1

If set to Yes, defines the terminal(pin) as having an internal connection through a passive device to a second, more positive, supply voltage in addition to the internal connection to an active device through a supply voltage.

Passive Pull-down1

If set to Yes, defines the terminal(pin) as having an internal connection through a passive device to a second, more negative, supply voltage in addition to the internal connection to an active device through a supply voltage.

Rated Voltage

Sets the maximum voltage that may be applied to the terminal(pin), beyond which damage may occur.

Power Dissipation

Sets the maximum power that may be applied to the terminals(pin), beyond which damage may occur.

1 Use the Symbol Creator tool settings to specify whether you want a graphic annotation to be shown for the property. See Configuring Symbol Creator Tool Settings.
