| 【Difficulty】： |
Ⅰ.This product adopts an Intel Centrino chip; Ⅱ.The North Bridge and the CPU are not in the same side; Ⅲ.Features: cross connection of 800MHz FSB bus, 6-layer board, and small routing layers. Ⅳ.It is required to have less routing on the surface layer as this board will be provided to the third party as a reference board and the board should be designed strictly according to the "Yellow Book" Ⅴ.The coverage rate of ICT should reach 95% (including the single-point network) |
| 【Countermeasure】： |
Ⅰ.Thorough research on the characteristics of pin definitions, comprehensive planning; Ⅱ.Properly would lines inside the North Bridge and the CPU; Ⅲ.Fully understanding of the key degree of signals, treated them respectively, and distributed important signals in priority routing layers: Ⅳ.Upon placement, we considered ICT requirements, and left necessary space for ICT. Multi-person concurrent design assured the board design progress; |
| 【Result】： | The first version of the demo board was debugged successfully, so it was very smooth to conduct software debugging. |
