BitVector is a family of types for storing multiple bits of information in a single value.
BitVector is a family of types for storing multiple bits of information in a single value. This type has three subtypes that can be used to model different behaviours:
The Bits type corresponds to a vector of bits that does not convey any arithmetic meaning.
The Bits type corresponds to a vector of bits that does not convey any arithmetic meaning.
val myBits1 = Bits(32 bits) val myBits2 = B(25, 8 bits) val myBits3 = B"8'xFF" val myBits4 = B"1001_0011
Bits factory used for instance by the IODirection to create a in/out Bits
