BinaryToGrayConverter constructor

BinaryToGrayConverter(
  1. Logic binary, {
  2. bool reserveName = false,
  3. bool reserveDefinitionName = false,
  4. String? definitionName,
})

Creates a BinaryToGrayConverter instance with the specified binary input.

The binary parameter is the binary input that you want to convert to Gray code. The width of the input binary determines the width of the Gray code output.

Implementation

BinaryToGrayConverter(Logic binary,
    {super.reserveName, super.reserveDefinitionName, String? definitionName})
    : super(
          definitionName:
              definitionName ?? 'BinaryToGrayConverter_W${binary.width}') {
  final inputWidth = binary.width;
  binary = addInput('binary', binary, width: inputWidth);
  final grayVal = addOutput('gray', width: inputWidth);

  Combinational([
    Case(
        binary,
        [
          for (var i = 0; i < (1 << inputWidth); i++)
            CaseItem(Const(i, width: inputWidth), [
              grayVal <
                  Const(binaryToGray(LogicValue.ofInt(i, inputWidth)),
                      width: inputWidth)
            ])
        ],
