Simulating real-time software components based on logical execution time

A method for simulating a real-time system using a block-oriented simulation system with a static block-update order, the method comprising:

• providing a first task function block that includes a task release block, a task execution block, a task termination block, and a delay block, wherein the first task function block has a logical execution time interval in which are performed functions of the task release block, the task execution block, the task termination block and the delay block;
• triggering, using a first trigger block, the task release block at a first time, wherein the task release block is triggered at a beginning of the logical execution time interval;
• triggering, using the first trigger block or a second trigger block different from the first trigger block, the task execution block at a second time after or equal to the first time;
• triggering, using the second trigger block, the task termination block at a third time at or after the second time, wherein the task termination block is triggered at an end of the logical execution time interval;
• and
• delaying data flow between at least one of:
• (i) the task release block and the task execution block and (ii) the task execution block and the task termination block,
• wherein the task execution block calculates, when triggered, an output value dependent on an input value in accordance to a desired transfer function,
• wherein the task release block receives, when triggered, data from a data source and sets the input value of the task execution block dependent on the received data, and
• wherein the task termination block provides, when triggered, the output value of the task execution block as data to a data sink.

A non-transitory computer readable medium storing computer software that simulates a real-time system using block-oriented simulation with a static block-update order, the computer software comprising:

• executable code that provides a first task function block that includes a task release block, a task execution block, a task termination block, and a delay block, wherein the first task function block has a logical execution time interval in which are performed functions of the task release block, the task execution block, the task termination block and the delay block;
• executable code that provides a first trigger block and a second trigger block that is different from the first trigger block;
• executable code that triggers, using the first trigger block, the task release block at a first time, wherein the task release block is triggered at a beginning of the logical execution time interval;
• executable code that triggers, using the first trigger block or the second trigger block, the task execution block at a second time after or equal to the first time;
• executable code that triggers, using the second trigger block, the task termination block at a third time at or after the second time, wherein the task termination block is triggered at an end of the logical execution time interval;
• and
• executable code that delays data flow between at least one of:
• (i) the task release block and the task execution block and (ii) the task execution block and the task termination block,
• wherein the executable code that provides the task execution block calculates, when triggered, an output value dependent on an input value in accordance to a desired transfer function,
• wherein the executable code that provides the task release block receives, when triggered, data from a data source and sets the input value of the task execution block dependent on the received data, and
• wherein the executable code that provides the task termination block provides, when triggered, the output value of the task execution block as data to a data sink.
