PartQuest Portal Subscription: Essential tier
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.
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 High |
If set to Yes, defines the terminal(pin) to be active on a high level. |
Active Low |
If set to Yes, defines the terminal(pin) to be active on a low level. |
Hysteresis |
If set to Yes, defines the terminal(pin) to be hysteresis. |
Enable |
If set to Yes, defines the terminal(pin) function to be an enable. |
Amplifier |
If set to Yes, defines the terminal(pin) function to amplify the signal. |
Passive Pull-up |
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-down |
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. |
You can specify IEEE ANSI graphic annotation to appear with the following properties: Active High, Active Low, Amplifier, Enable, Hysteresis, Passive Pull-down, and Passive Pull-up.
