As title, I want to covert Vec(Bool()) into UInt value.

For example

class MyModule extends Module {

  val io = IO(new Bundle {
    val in_data    = Input (Vec (3, Bool() ) 
    val result     = Output(UInt(5.W))
  })

  //how can I convert io.in_data to Uint and the assign to io.result
  //I will get io.result = 7 when in_data(1, 1, 1) 
}

You can use .asUInt to cast a Vec to Bools (or any Chisel Data) to UInt.

If you need to cast from UInt back to Vec or Bools you can use .asBools
