Issue: Update Zynq to Production Silicon
PCB: no change.
Parts: load IC16 with XC7Z020-1CLG484C
Issue: Update DDR3 to newer device
PCB: no change.
Parts: load IC25 and IC26 with MT41K128M16JT-125:K
Issue: IC31 IN oscillates due to insufficient
decoupling
PCB: change C374 pad size to 0603.
Parts: load C374 with 10uF 10V.
Issue: C89 incorrect value
PCB: no change
Parts: Load C89 with 150uF tantalum (already implemented)
Issue: Two DDR3 power/termination pins not in
schematic part
PCB: fix DDR3 part to include two missing pins
Parts: no change
Issue: CKE signal pull-down revised
PCB: add 0402 resistor from CKE to VTT.
Parts: Load new resistor with 40ohm resistor.
Issue: SD Card clock requires termination resistor
PCB: add series termination resistor to SD Clock.
Parts: load new resistor with 50ohm resistor.
Issue: Heat issues
PCB: add two 1x2 pin headers (5V/GND and 12V/GND) to power a
fan if needed
Parts: load headers; add heat sink
Issue: VBUS must connect to power pin on USB
connector
PCB: move existing 0402 resistor between USB power pin and VBUS
Parts: no change
Issue: Parts not fitting pads (J12, L7)
PCB: Extended pads on L7 to accommodate larger parts
Parts: load only specified parts
