Not gates returning fixed values.

For better or for worse, I'm using two Not gates in my DMux4Way.hdl chip.
I call them so:

    Not(in=sel[0], out=NSel0);
    Not(in=sel[1], out=NSel1);


The weird thing is, when I run the chip. The Not gates both return 1 regardless of the value sel[0] or sel[1].
I've tried the same notation in another chip implementation and it works just fine.

Cluelessly,
Philip.
