class Bits extends BitVector with DataPrimitives[Bits] with BaseTypePrimitives[Bits] with BitwiseOp[Bits]

The Bits type corresponds to a vector of bits that does not convey any arithmetic meaning.

Example:

  1. val myBits1 = Bits(32 bits)
val myBits2 = B(25, 8 bits)
val myBits3 = B"8'xFF"
val myBits4 = B"1001_0011
