        val led = Output(Bool())
    })

    val counter = RegInit(0.U(24.W))

class Counter2Bit extends Module {
    val io = IO(new Bundle {
        val count = Output(UInt(2.W))
    })

    val cnt = RegInit(0.U(2.W))
    cnt := cnt + 1.U
    io.count := cnt
}

object Counter2Bit extends App {
    chisel3.Driver.execute(args, () => new Counter2Bit)
}

A simple 2-bit synchronous counter using Chisel.
