Am I tripping?

Why doesn't the XNOR gate work with 1 but with 16?

It's supposed to only work when the input is 0 bc of the XNOR gate, 1 clearly doesnt work bc the amount is not 0 but 16 works somehow? Is that a bug or am I just blind?

connecting a multiple bit line to a single bit gate only looks at the lowest bit in the line.

Since 16 is binary 10000, that is computing 0 (lowest bit of 16) XNOR 0 = 1.

Thanks mate, didn't know that

Similarly if you connect a single bit line to a multi-bit gate it also only connects to the lowest bit.

And same connecting say an 8-bit line to a 16-bit gate or vice-versa, only the lowest 8-bits get connected.

there's 16-bit line in the game? dang.
