Hi! I'm trying to do such simple thing:
Xor16(a=nowide, b=out5, out=outt);
what's illegal in it? it's giving me 'Sub bus of an internal node may not be used' error message.
This is a limitation in the Hardware Simulator. You need to do the sub-busing when you create the internal bus:
Xor16(a=nowide, b=out5, out[0:7]=outt);
