GZ 16o8i testing notes

So I loaded the 16o8i.xsvf and executed the gz_16o8i.  The test program  demonstrates the following.


1. Toggling all outputs.

2. Toggling alternate outputs.

3. Walking outputs.

4. Reading inputs.


The first 3 demonstrations look OK, though there are only 8, not 16 LED indicators displaying the results.

I have not tried 4, because I am thinking of first making another level shifter, this time a shift down version.
