WebChisel3 API may implement the reductions as folds with initial values and we document it as such. I'd propose then that chisel3.strict doesn't include andR and instead uses foldAndTrue and foldOrFalse. For (4), what I mean is val foo = bar.andR could emit as: red (a ## b) === red (red (a) ## red (b)), so xorR should return 0 in this case. edited WebChisel Data Types I Bit width can be explicitly speciﬁed with a width type I SInt will be sign extended I UInt will be zero extended 0.U(32.W) "habcd".U(24.W)-5.S(16.W) I Bundles for a named collection of values I Vecs for indexable collection of values I Chisel data types are different from Scala builtin types (e.g., Scala’s Int) 3/35
