Abstract: A system for simulating a real-time system using a block-oriented simulation with a static block-update order comprises: a clock providing a time base; a first task function block with a task release block, a task execution block, a task termination block, and a delay block; a first trigger block that triggers the task release block at a first time; and a second trigger block that triggers the task termination block at a third time. The task execution block calculates an output value dependent on an input value. The task release block receives input data from a data source and sets the input value. The task termination block provides the output value to a data sink. The first or second trigger function block triggers the task execution block at a second time provided by the clock. The delay block is arranged between the task release and task termination blocks.

Abstract: A system for executing distributed software under hard real-time conditions comprises a plurality of nodes and a communication channel. Nodes are allowed to transmit data across the communication channel within time windows relative to repetitive communication time intervals of the communication channel, wherein a number of bytes transmitted within the communication time windows may vary from communication time window to communication time window. The data may be transmitted as a message comprising a representation of an identifying tag and a representation of the data. Also a number of bytes representing respective tags may vary from communication time interval to communication time interval.

Abstract: Methods and implementations for constructing a real-time system are disclosed. The real-time system includes at least one module, each module having at least one mode. According to an embodiment, a method comprises: defining a mode period for each mode for a repeated execution of the respective mode by the corresponding module; for each mode, defining one or more synchronous tasks to be executed by the real-time system, whereby each synchronous task is associated with a logical execution time during which the task execution has to be completed; defining an integer number of time-slots for the mode period of each mode; assigning to each task at least one time slot during which the task is to be executed.
