Incompatibility errors

Logisim insists that you never connect two different bit widths together. When it detects that you have done this, it will display an orange error message saying "Incompatible widths."

In this screen shot, I have connected the 3-bit output pin to a 1-bit AND gate. Logisim helpfully draws the offending wire in orange, and it tells which widths are incompatible. For the wire to work, we will need to repair this; in this case, we would change the AND gate's Bit Width attribute to 3.

When you have an incompatibility error outside the part of the canvas you are currently viewing, Logisim will helpfully draw an arrow to tell you where you can find the error.
