Boolean signal source that mimics a radio button: Via a table, a radio button is pressed (i.e., the output 'on' is set to true) and is reset when an element of the Boolean vector 'reset' becomes true. If both appear at the same time instant, setting the button according to the table has a higher priority as resetting the button. Example:

RadioButtonSource start(buttonTimeTable={1,3}, reset={stop.on});
RadioButtonSource stop (buttonTimeTable={2,4}, reset={start.on});

The "start" button is pressed at time=1 s and time=3 s, whereas the "stop" button is pressed at time=2 s and time=4 s. This gives the following result:
