I have been struggling with the PulSAR Pmod development kit.  I wanted to share my experience and get feedback from Analog .  The schematic I am working on was draw by J. Fitzgerald, dated 7/23/14 titled AMP_ADC.  The pin outs of the footprint and symbol defies header pin numbering conventions.  This is the first time in my career that I have seen header pins numbered clockwise . I wasted a day of my time debugging the development board as a result.  I had to go to the Gerber files to determine how the pins were numbered.  ICs have a conventional pin number scheme -- I recommend that Analog devices follows numbering conventions in the future so that customer do not need to refer to layouts.
