Or16 Gate

Truth Table
a[x] | b[x] | f(a[x],b[x])
----------------------------
0      | 0     | 0
0      | 1     | 1
1      | 0     | 1
1      | 1     | 1

--------------------------------------------------
CHIP Or16
{
    IN a[16], b[16];
    OUT out[16];

    PARTS:
    Or(a=a[0], b=b[0], out=out[0]);
    Or(a=a[1], b=b[1], out=out[1]);
    Or(a=a[2], b=b[2], out=out[2]);
    Or(a=a[3], b=b[3], out=out[3]);
    Or(a=a[4], b=b[4], out=out[4]);
    Or(a=a[5], b=b[5], out=out[5]);
    Or(a=a[6], b=b[6], out=out[6]);
    Or(a=a[7], b=b[7], out=out[7]);
    Or(a=a[8], b=b[8], out=out[8]);
    Or(a=a[9], b=b[9], out=out[9]);
    Or(a=a[10], b=b[10], out=out[10]);
    Or(a=a[11], b=b[11], out=out[11]);
    Or(a=a[12], b=b[12], out=out[12]);
    Or(a=a[13], b=b[13], out=out[13]);
    Or(a=a[14], b=b[14], out=out[14]);
    Or(a=a[15], b=b[15], out=out[15]);
}
--------------------------------------------------

Again you just take 2 arrays of 16 bits and OR each set of 2 bits from each array with the same index.
