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 ()) . http://www2.imm.dtu.dk/courses/02139/06_fsm.pdf

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?
