WebBy default, the Chisel compiler will size each constant to the minimum number of bits required to hold the constant, including a sign bit for signed types. Bit widths can also … WebJan 13, 2024 · Next, notice the inputs and outputs are all 4-bit UInts. Chisel has built-in width inferencing, and if you look at the cheatsheet, you’ll see that the bitwidth of a normal summation is equal to the maximum bitwidth of the two inputs. This means that. 1: val sum = io.in_a + io.in_b:
