The CERN design office improved and finalised the design
http://edms.cern.ch/nav/EDA-02839/EDA-02839-V1-0 on 25 September 2013.

The design office has detected the following issues that may be looked into further to see if they may give problems:

• Composants trop proches des uns et des autres: (pas modifié)
• Vias dans les pads SMD (141 erreurs): (pas modifié)
• Fil qui coupent des plans (paires diff. !!): (pas modifié)
• Fil Antennes: (Fait les principaux)

Or, in English:

• Components too close one to another: (not modified)
• Vias-in-pad on SMD components (141 errors): (not modified)
• Wire that cuts power planes (differential pairs!!): (not modified)
• Antenna wires (loose on one end): (did the most important ones)
