Multi-terminations

A multi-termination is any connectivity pattern where a single pin doesn't map to a single, simple net-to-pin relationship. Connectivity Hub supports three use cases:

1. Multiple nets connecting to the same pin.
2. One net connecting to multiple pins.
3. Loopback — a pin connecting back to another pin on the same device/component.

Prerequisite

To map multi-terminations, connectivity must first be synthesized on the component — multi-termination mapping works on synthesized connectivity, the same way ordinary pin mapping does.

Adding multi-termination connectivity: the Interface Map

Multi-terminations are set up via the Edit Interface Map action:

1. Add signal(s)/message(s) to the Interface Map.
2. Specify the interface and carrier.
3. The updated Interface Map provides additional connectivity, which can then be mapped to pins.

Multi-terminations are identified in the pin list with a dedicated icon, so they're visually distinguishable from ordinary one-to-one pin mappings once added.

Visualizing and saving multi-terminations

• Visualizing component connectivity displays multi-terminations directly.
• Saving the component as an ICD respects multi-terminations — an ICD correctly records multiple nets defined on the same pin rather than collapsing them.
• In a schematic, multi-terminations result in a single net — i.e. the multiple logical connections captured in the ICD render as one physical net in the schematic view, which is expected and not a data-loss issue.
