simulator error? Bit

[dmoeller]

My instructor showed us how to make the Bit chip. the ouput of the DFF is connected to the load on the Mux before it. When i run this in the hardware simulator, I get cannot connect parts output pin to gates input.

HDL does not allow you to use any signal mentioned on the OUT line.

CHIP Bit {
    IN in, load;
    OUT out;        <=======

    PARTS:
    // Put your code here:
}

You must have another "out=" connection on the DFF that can be used to connect to the Mux.

DFF (in=muxOut, out=out, out=dffOut);

I have:
Mux (a=in, b=load, out=W1);
DFF (in=W1, out=load, out=out);

Mux is missing one of its inputs.

aha, yes it is. Sel. but now thinking about it,  I have no idea what sel should be...

Look at the schematic diagram of Bit in figure 3.1.  It shows what the connections to the Mux are.
Since the data inputs, a and b, are not labeled, you need to figure out on your own which one is which.
