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 with 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 pad designator that corresponds with the pin. Note that the pad 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 of 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.

  The mapping of component pins to model pins can be updated in the Model Map dialog.
• 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.

  • For a multi-part component, the power net connections should ideally be assigned through the use of Part Zero. A pin is included in Part Zero by placing it, then setting the Part Number property to 0. Pins placed in Part Zero will appear on all parts.
  • The pins placed in Part Zero can also be hidden if required. While this practice is not recommended, for each pin that is required to connect to a power net in this way, enter the net name in the Hidden Net Name field in either the SCHLIB List panel or the SCH List panel and then disable the Show option in the Component Pin Editor dialog (or enable the Hide option in the SCHLIB List panel or the SCH List panel).

  • Show – reflects whether the pin is visible on the sheet (enabled) or hidden (disabled). While this practice is not recommended, the power pins of multi-part components can be hidden when their display would otherwise cause unnecessary clutter on the schematic sheet.

    Hidden pins for a component can be revealed on the sheet in the schematic editor or schematic library editor by enabling the Show All Pins option in the Pins region of the Properties panel. In the schematic library editor, the Show Hidden Pins option must also be enabled in the Edit main menu.
  • 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.

    To negate (include a bar over the top of) a pin name, use one of the following methods:

    • Include a backslash character after each character in the pin name (e.g. H\O\L\D\).
    • Enable the Single '\' Negation option on the Schematic – Graphical Editing page of the Preferences dialog, then include one backslash character at the start of the pin name (e.g. \HOLD).
• 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.
  Upon clicking OK in the dialog, any newly added pins will be initially placed at the bottom-right of the component (or part thereof). Reposition as required.
• Remove – click this button to remove the currently selected pin from the component. A confirmation dialog will open; 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 design space (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 open; 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 design space 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 design space 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.
• 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.

    To negate (include a bar over the top of) a pin name, use one of the following methods:

    • Include a backslash character after each character in the pin name (e.g. H\O\L\D\).
    • Enable the Single '\' Negation option on the Schematic – Graphical Editing page of the Preferences dialog, then include one backslash character at the start of the pin name (e.g. \HOLD).

  • Function – use this field to specify a number of names (functions) for the multi-functional pin being edited. Enter an alternative name of the pin, then press Enter or click the  button at the right of the field. Added alternative names will be shown as labels below the field. Click 'x' in the label of a function to remove it.

    After placing the component on a schematic sheet, the function that will be shown as the pin name can be selected on the Pins tabs of the Properties panel in the Component mode.
    The ability to specify multiple functions for a pin is currently in Closed Beta and is available when the Schematic.CustomNamesForMultifunctionalPins option is available in the Advanced Settings dialog. The Advanced Settings dialog is accessed by clicking the Advanced button on the System – General page of the Preferences dialog. If any changes are made in the Advanced Settings dialog, the software must be restarted in order for the changes to take effect.
  • 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).
  • 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.
    • A pin is included in Part Zero by placing it, then setting the Part Number property to 0. Pins placed in Part Zero will appear on all parts.
    • The pins placed in Part Zero can also be hidden if required. While this practice is not recommended, for each pin that is required to connect to a power net in this way, enter the net name in the Hidden Net Name field in either the SCHLIB List panel or the SCH List panel and then disable the Show option in the Component Pin Editor dialog (or enable the Hide option in the SCHLIB List panel or the SCH List panel).
  • 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
  These symbols are purely graphical. The true electrical property of the pin is determined by the entry set for the pin's Electrical Type.

  • Inside – use to optionally add a symbol to the pin on the inside of the component graphic.

  • Inside Edge – use to optionally add a symbol to the pin on the inside edge of the component graphic.
  • Outside Edge – use to optionally add a symbol to the pin on the outside edge of the component graphic.
  • Outside – use to optionally add a symbol to the pin on the outside of the component graphic.

  • Line Width – use this field to determine the width of the line used to draw the symbols. 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.

    The Line Width setting will also apply to the automatic symbol used in relation to the pin's defined Electrical Type.
