Create Multiple Pin Pairs

Pin pairs can be created in Constraint Browser by selecting signals in the Signals tree, and clicking Create Multiple Pin Pairs on the ribbon or clicking Edit > Create Multiple Pin Pairs. Alternatively, right-click selected signals in the Signals box and select Create Multiple Pin Pairs on the assist menu. You can configure and preview new pin pairs in the displayed Create Multiple Pin Pairs dialog. This dialog is not available in Constraint Viewer.

  • In Constraint Browser for eCADSTAR Schematic Editor, signals may include E-Nets and differential pairs.
  • In Constraint Browser for eCADSTAR PCB Editor, signals may include E-Nets, differential pairs and busses.

 

Note
The details of the pin pairs that you create are shown in the Pin Pair Routing Report dialog. However, the following limitations apply:
  • You cannot specify a topology for pin pairs in a non High Speed environment.
  • The Track Width Stack constraint that you specify for a pin pair in Constraint Browser is not adhered to by the Add Route or Autoroute commands. This is specified in the Routing Tab, in the Signals Section, Signals tab in Constraint Browser.

Allow creating pin pairs in the driver component
Allows you to select a receiver component that is already specified as a driver.
  • Selected: a component can still be selected in the 3: Select Receivers section even if already selected in the 2: Select Drivers section.
  • Not selected: if a component is selected in the 2: Select Drivers section, then it cannot be selected in the 3: Select Receivers section.
  Component Displays the names of possible receiver components for the signals that are selected in the Signal box. If components are selected in the Select Drivers box, the contents of the Select Receivers box are automatically filtered to only show appropriate receiver components. Click a component to specify it as a receiver component for a pin pair. Select multiple components using the Ctrl or Shift keys, or by dragging the cursor.
  Part Displays the part name for the relevant component.
Preview box   The Preview box is displayed at the right side of the Create Multiple Pin Pairs dialog. It shows the associated pin pair for each pair of driver and receiver components that you select in the Select Drivers and Select Receivers boxes, for the signals that you select in the 1: Select Signals box.

 

Signal Displays the signal that is associated with each pin pair. The pin pairs are specified by selecting components in the Select Drivers and Select Receivers boxes.

 

Pin Pair Displays the pin pair for the pair of components selected in the Select Drivers and Select Receivers boxes. Pin pairs are displayed for each relevant signal.
Create   Creates new pin pairs for the signals that are displayed in the Preview box. The new pin pairs are displayed in the Signals tree in Constraint Browser, in the Pin Pairs folder for the relevant signals.
Close   Closes the Create Multiple Pin Pairs dialog.
