Signed and unsigned integers are considered subsets of fixed-point numbers and are represented by types SInt and UInt respectively. Signed fixed-point numbers, including integers, are represented using two's-complement format. Boolean values are represented as type Bool.

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 ¶ Webbe automatically converted to Chisel types, but this can cause type ambiguity and requires an additional import. The SInt and UInt types will also later support an optional exponent field to allow Chisel to auto-matically produce optimized fixed-point arithmetic circuits. 4 Combinational Circuits A circuit is represented as a graph of nodes ...
