Abstract: The automatic generation of a real-time scheduler for scheduling the execution of tasks on a real-time system is disclosed. The scheduler may allow task overruns in the execution of the tasks on the real-time system. The task overruns may occur when the execution of a task for a current sample hit is not completed before a next sample hit. When the task overruns occur, the scheduler may delay the execution of the task for the next sample hit until the execution of the task for the current sample hit is completed. The execution of the task for the next sample hit is performed after the execution of the task for the current sample hit is completed. The present invention may enable users to input information relating to the behavior in real-time execution of the graphical programs or models. The present invention may simulate the graphical programs or models using the information on the behavior of the graphical programs or models executed in the real-time execution.

Abstract: A device receives a model that includes model elements scheduled to execute in time slots on a hardware device. The device identifies time slots, of the time slots, that are unoccupied or underutilized by the model elements, and identifies a set of model elements that can be moved to the unoccupied time slots without affecting a behavior of the model. The device calculates a combined execution time of the model elements, determines whether the combined execution time of the model elements is less than or equal to a duration of a first time slot of the time slots, and schedules the model elements for execution in the first time slot when the combined execution time of the model elements is less than or equal to the duration of the first time slot.
