Setting the Equipotential Attribute for a Pin

You can set the Equipotential attribute for a pin in Capital Logic Designer. This provides the ability to merge nets that have been defined separately into a single signal. The Equipotential attribute is defined on an instance of a device pin. That means that it is stored within a design and can therefore be revised with that design. In other words, you can have multiple revisions of a system design and the definition of equipotential signals can be different in each.

For details of the effect of setting this, see Equipotential Nets at a Pin.

Procedure

Right-click the device pin and choose the Properties option from the pop-up menu.
The Edit Properties dialog box displays. Go to the Attributes section of the General tab.
For the Equipotential attribute, click in the Value field and select a net name from the drop-down list. The listed nets are those that connect to the pin. The name that you select is the name that is used for the single signal in Capital Systems Integrator.If you select the blank value for the Equipotential attribute, the nets are not treated as equipotential. Note If the selected net is later deleted, the attribute changes to reference another net connected to the pin. If the deletion leaves just one net connected to the pin, the attribute remains set so that the equipotential behavior is preserved in case another net is later multitermed at the pin.
Click the OK button to exit the Edit Properties dialog box.Note When wiring is synthesized in Capital Systems Integrator, the system recognizes the equipotential attribute and creates a single signal containing the connectivity of all the nets attached to this device pin. This signal is synthesized as a single entity.
