Compute

When using imperative behavior, one can declare the calculation of outgoing port values by using blocks of arbitrary statements. These statements are declared within the compute block. Moreover, one can define initial outgoing values and other calculations within the init block, which is especially relevant when using a delayed compute block.

component FahrenheitToCelsiusAndKelvinConverter {
  port sync in double fahrenheit,
       sync out double celsius,
       sync out double kelvin;

  init {
    kelvin = 0;
    celsius = -273.15;  // Equivalent to 0 °K
  }

  <<delayed>> compute {
    celsius = (fahrenheit - 32) * 5.0 / 9.0;
    kelvin = (fahrenheit + 495.67) * 5.0 / 9.0;
  }
}

Warning

Compute blocks can only read from synchronous ports, but write to all port regardless of the timing.
