Planificar componentes del modelo
Planificar los componentes del modelo para realizar la simulación o la integración con un planificador externo requiere que los algoritmos existan en bloques atómicos Subsystem o Model. El ritmo de ejecución se especifica como periódico (subsistema planificado) o no periódico (subsistema de llamada a función).
Las particiones son componentes de un modelo que se ejecutan independientemente como tareas atómicas. En los modelos multitarea, las particiones se crean a partir de los componentes del modelo. Con las particiones, puede separar las partes del modelo que puede controlar explícitamente en la herramienta Schedule Editor.
Schedule Editor es una herramienta de planificación que representa los componentes del modelo conocidos como particiones, las conexiones de datos entre ellos y el orden de esas particiones. Esta herramienta solo puede utilizarse en los componentes existentes, como los subsistemas atómicos, las funciones de exportación y los bloques de modelos. Schedule Editor es una herramienta interactiva que permite ver y editar fácilmente la planificación de los componentes del modelo.
