Chisel uint to sint
WebTo cast a Bool, a Bits, or an SInt into a UInt, you can use U (something). To cast things into an SInt, you can use S (something). // Cast an SInt to Bits val myBits = mySInt.asBits // Create a Vector of Bool val myVec = myUInt.asBools // Cast a Bits to SInt val mySInt = S(myBits) Bit extraction ¶ WebChisel 2.0 Manual Jonathan Bachrach, Huy Vo, Krste Asanovic´ ... UInt SInt Bundle Vec Aggregate Figure 2: Chisel type hierarchy. Built-in scalar types include SInt, UInt, and Bool, and built-in aggregate types Bundle and Vec allow the user to expand the set of Chisel datatypes with collections of other types.
