Component Pin Editor

The Component Pin Editor dialog

Summary

The Component Pin Editor dialog displays all pins for either the component in the active schematic library document or a placed component (or part thereof) in the schematic editor. It provides a single, convenient location for you to modify certain properties of any pin associated to that component. In addition to providing a means of editing pin properties, the dialog also allows you to add new pins or delete existing ones.

Access

The Component Pin Editor dialog can be accessed from either the schematic editor or the schematic library editor by performing the following steps:

1. Double-click on the desired placed component (or right-click then choose Properties from the context menu) to open the Properties panel in Component mode.
2. On the Pins tab of the panel, select a pin then click . 

Options/Controls

Pin Grid

This area presents all pins for the component. For each pin, the following information is displayed:

• Designator - the numerical identifier of the pin. Each pin of a part must have a unique designator.
• Name - the display name for the pin. Note that the pin name is optional, this field can be left blank if required. Alternatively, enter a string into the Name text field, then use the Name checkbox to display or hide the name.
• Desc - the description for the pin.
• Footprint Model Mapping - the title of this is the pad of the indicated linked footprint model to which this pin of the schematic component is mapped. A separate field is presented for each linked footprint model.

• Type - the electrical type of the pin. This type is used when compiling a project or analyzing a schematic document to detect electrical connection errors (using the Electrical Rules Check feature). Available types are: Input, I/O, Output, Open Collector, Passive, HiZ, Open Emitter, and Power.
• Owner - the parent part to which the pin is associated. For a single-part component, this entry will always be 1; it is only meaningful for a multi-part component. A multi-part component also includes a non-graphical part, Part Zero. Part Zero is used for pins that are to be included in all parts of the multi-part component, for example, power pins. 

• Show - reflects whether the pin is visible on the sheet (enabled) or hidden (disabled). The power pins of multi-part components are typically hidden when their display would otherwise cause unnecessary clutter on the schematic sheet. 

• Number - used to determine whether the designator for the pin is displayed (enabled) or hidden (disabled) when the parent part is placed on a schematic sheet. 
• Name - used to determine whether the display name for the pin is displayed (enabled) or hidden (disabled) when the parent part is placed on a schematic sheet. 

• Pin/Pkg Length - this is the pin-package length. 
• Propagation Delay - displays the propagation delay, which is the amount of time it takes for the head of the signal to travel from the sender to the receiver.
• Add - click this button to add a new pin to the component. The new pin will be assigned the next available designator (which can be pin 0), and will have the following default properties:
  • Name - 1
  • Desc - blank
  • Mapping - all 0
  • Type - Passive
  • Owner - the number of the active/selected part.
  • Show/Number/Name - all enabled.

• Remove - click this button to remove the currently selected pin from the component. A confirmation dialog will appear - click Yes to proceed with the removal. If removing a pin from a placed component instance on a schematic, you may need to rewire any existing wiring that was connected to that pin.

Right-Click Menu

The grid right-click menu offers the following commands:

• Jump - use to jump to the currently selected pin within the workspace (zoomed and centered (where possible)).
• Add - use to add a new pin to the component (or part thereof).
• Remove - use to remove the currently selected pin from the component. A confirmation dialog will appear; click Yes to proceed with the removal.
• Edit - this command is non-functional.
• Report - use to open the Report Preview dialog.

Properties Region

General Tab

• Location
  • (X/Y)
    • X (first field) - the current X (horizontal) coordinate of the reference point of the object, relative to the current workspace origin. Edit to change the X position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 
    • Y (second field) - The current Y (vertical) coordinate of the reference point of the object, relative to the current origin. Edit to change the Y position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 
  • Rotation - use the drop-down to select the rotation. Choices are: 0 Degrees, 90 Degrees, 180 Degrees, and 270 Degrees.
• Properties
  • ​Designator - the numerical identifier of the pin. Each pin of a part must have a unique designator. Use  or  to determine whether the Designator for the pin is displayed or hidden when the parent part is placed on a schematic sheet.​
  • Name - use to specify an optional display name for the pin. By default, a newly-placed pin will be named using the designator value. Supplying a display name is particularly useful for IC-type components where a meaningful name enables you to see quickly how the pin is being used. Use  or  to determine whether the Name for the pin is displayed or hidden when the parent part is placed on a schematic sheet.​​
  • Electrical Type - use the drop-down to set the electrical type of the pin. This is used when compiling a project or analyzing a schematic document to detect electrical connection errors (using the Electrical Rules Check feature). Available types are: Input, I/O, Output, Open Collector, Passive, HiZ, Open Emitter, and Power.
  • Description - enter a meaningful description of the pin, if desired.
  • Pin Package Length - enter the pin-package length. The unit will automatically be entered after you press Enter.
  • Propagation Delay - enter the propagation delay. The unit will automatically be entered after you press Enter.
  • Part Number - this field is available when the pin is being added to a multi-part component. Use the up/down arrows to specify the part to which the pin is to be associated. A multi-part component also includes a non-graphical part, Part Zero. Part Zero is used for pins that are to be included in all parts of the multi-part component, for example, power pins.

• Preview Window - this area provides instant visual feedback as you change various options, enabling you to adjust the look and feel of the pin to meet design requirements.
• Pin Length - use to specify the length of the pin in accordance with the currently defined units of measurement. Click the color box to edit the color of the pin.

Symbols Region

• Inside - use to optionally add a symbol to the pin on the inside of the component graphic. Choose from: No Symbol, Postponed Output, Open Collector, Hiz, High Current, Pulse, Schmitt, Open Collector Pull Up, Open Emitter, Open Emitter Pull Up, Shift Left, and Open Output.
• Inside Edge - use to optionally add a symbol to the pin on the inside edge of the component graphic. Choose from: No Symbol and Clock.
• Outside Edge - use to optionally add a symbol to the pin on the outside edge of the component graphic. Choose from: No Symbol, Dot, Active Low Input, and Active Low Output.
• Outside - use to optionally add a symbol to the pin on the outside of the component graphic. Choose from: No Symbol, Right Left Signal Flow, Analog Signal In, Not Logic Connection, Digital Signal In, Left Right Signal Flow, and Bidirectional Signal Flow.
• Line Width - use this field to determine the width of the line used to draw the symbols. Choose from either Small or Smallest. This provides support for meeting GOST standards, which stipulates that these symbols should be of the same width as the line used to draw the component's symbol.
