class SInt extends BitVector with Num[SInt] with MinMaxProvider with DataPrimitives[SInt] with BaseTypePrimitives[SInt] with BitwiseOp[SInt]
The SInt type corresponds to a vector of bits that can be used for signed integer arithmetic.
val mySInt = SInt(8 bits) mySInt := S(4, 8 bits) + S"0000_1111" mySInt := S(4) - S"h1A"
