verilogContents method

  1. @override
String verilogContents(
  1. int indent,
  2. Map<String, String> inputsNameMap,
  3. Map<String, String> outputsNameMap,
  4. String assignOperator,
)
override

Returns a String of SystemVerilog to be used in generated output.

The indent is used for pretty-printing, and should generally be incremented for sub-Conditionals. The inputsNameMap and outputsNameMap are a mapping from port names to SystemVerilog variable names for inputs and outputs, respectively. The assignOperator is the SystemVerilog operator that should be used for any assignments within this Conditional.

Implementation

@override
String verilogContents(int indent, Map<String, String> inputsNameMap,
    Map<String, String> outputsNameMap, String assignOperator) {
  final padding = Conditional.calcPadding(indent);
  final verilog = StringBuffer();
  for (final iff in iffs) {
    final header = iff == iffs.first
        ? 'if'
        : iff is Else
            ? 'else'
            : 'else if';

    final conditionName = inputsNameMap[driverInput(iff.condition).name];
    final ifContents = iff.then
        .map((conditional) => conditional.verilogContents(
            indent + 2, inputsNameMap, outputsNameMap, assignOperator))
        .join('\n');
    final condition = iff is! Else ? '($conditionName)' : '';
    verilog.write('''
$padding$header$condition begin
$ifContents
${padding}end ''');
  }
  verilog.write('\n');

  return verilog.toString();
}
