extend method
- int newWidth,
- LogicValue fill
Returns a new LogicValue with width newWidth
where the most
significant bits for indices beyond the original width are set
to fill
.
The newWidth
must be greater than or equal to the current width or an
exception will be thrown. fill
must be a single bit (width=1).
Implementation
LogicValue extend(int newWidth, LogicValue fill) {
if (newWidth < width) {
throw Exception(
'New width $newWidth must be greater than or equal to width $width.');
}
if (fill.width != 1) {
throw Exception('The fill must be 1 bit, but got $fill.');
}
return [
LogicValue.filled(newWidth - width, fill),
this,
].swizzle();
}
