AD9914 Eval Schematic Questions

I am using the AD9914 in my design and am using Analog's evaluation board schematic as my starting point. I have a question about the decoupling capacitors:


On Page 3 of the eval board schematic, there are decoupling caps for 11 out of 18 power pins. The schematic does not show which pins these decoupling caps are associated with, nor does it show what is done with the remaining power pins. Additionally, the nets on the decoupling circuitry are labeled as 1.8V and 3.3V, but do not specify whether these are related to the digital or analog supplies.


I tried to puzzle these things out by looking at the gerber files.... but they are all in some antiquated, AOL proprietary file format (*.art). I have searched on how to open these, but the suggested methods did not work (opening in IE, XnView). Any advice on how I can view the gerber files?
