Interfaces compuestas

Agrupe las señales o los mensajes para reducir la complejidad del modelo en las interfaces de los componentes

Para reducir la complejidad del modelo, agrupe las señales individuales o los mensajes en líneas compuestas utilizando buses.

Los buses virtuales cumplen la mayoría de los requisitos de modelado de las interfaces compuestas y ofrecen la flexibilidad necesaria para combinar diferentes tipos de señales.

Para comparar las técnicas de modelado, consulte Composite Interface Guidelines.
