             Finally, is interesting to note that the consecutive channel components may not seem to connect. There are two types of occurences:
 
             1. The preceding channel's ending coordinates extend past the following channel's starting coordinates (example from a different path):

                There is no logical contradiction, but for clarification, it is best to see an explanation of the VPR coordinate system.

 :numref:`fig_path_2` shows the routing resources used in Path #2 and their locations on the FPGA.
 
 1. The signal emerges from near the top-right corner of the block to_FFC (OPIN:1479)  and joins the topmost horizontal segment of length 1 (CHANX:2073).

 2. The signal proceeds to the left, then connects to the outermost, blue vertical segment of length 0 (CHANY:2139).

 3. The signal continues downward and attaches to the horizontal segment of length 1 (CHANX:2040). 
+
 4. Of the aforementioned horizontal segment, after travelling one linear unit to the right, the signal jumps on a vertical segment of length 0 (CHANY:2166).

 5. The signal travels upward and promptly connects to a horizontal segment of length 0 (CHANX:2076).

 6. This segment connects to the green destination io (3,4).
