Mux constructor Null safety

Mux(
  1. Logic control,
  2. Logic d1,
  3. Logic d0,
  4. {String name = 'mux'}
)

Constructs a multiplexer which passes d0 or d1 to out depending on if control is 0 or 1, respectively.

Implementation

Mux(Logic control, Logic d1, Logic d0, {super.name = 'mux'}) {
  if (control.width != 1) {
    throw Exception('Control must be single bit Logic, but found $control.');
  }
  if (d0.width != d1.width) {
    throw Exception('d0 ($d0) and d1 ($d1) must be same width');
  }

  _controlName = Module.unpreferredName('control_${control.name}');
  _d0Name = Module.unpreferredName('d0_${d0.name}');
  _d1Name = Module.unpreferredName('d1_${d1.name}');
  _outName = Module.unpreferredName('out');

  addInput(_controlName, control);
  addInput(_d0Name, d0, width: d0.width);
  addInput(_d1Name, d1, width: d1.width);
  addOutput(_outName, width: d0.width);
