Chisel bool uint

WebSynonyms for CHISEL: pluck, squeeze, screw, cheat, stick, sting, hustle, beat, do, ream WebThe Chisel type of a Data is a Scala object. It captures all the fields actually present, by names, and their types including widths. For example, MyBundle (3) creates a Chisel Type with fields foo: UInt (3.W), bar: UInt (3.W)). Hardware is Data that is “bound” to synthesizable hardware. For example false.B or Reg (Bool ()) .

WebJan 19, 2024 · UInt Basically, I think there exists a customary abuse to UInt: using UInt as Bits. I think if a user need a UInt, they are using +, -, *, / and other numerical related operators. But these operator only exists in UInt, while not exists in Bits: WebFeb 5, 2024 · Chisel is a Scala DSL, so the Chisel Compiler is written in Scala.

WebMar 9, 2024 · One feature of a Vec[Bool] is that testing the values of each bit is simple. For example, let's say I have a module that gives back a UInt. I want to test a particular bit is set but I don't care what the other bits are. With a Vec[Bool] I could easily do this: dut.io.v(bit).expect(true.B) Is there an equivalent using UInt?
