DDR2 highperformance controller local_init_done, s_tracking_setup deadlock

Hi Yuying

Concerning your assumptions:

- It is hardware (using EP3SL50F780C2N FPGA)

- Timing Analyzer does allways pass. However, I'll check the report in detail. Do you know which signal / signal groups are related to the s_tracking_setup state (I read about voltage/temperature compensation control in the manual, but have no clue which physical elements / signals are involved)?

Further more, I migrated the a primitive sample design to the Stratix III evaluation board (due to another reason), which is using EP3SL150F1152C2N. The same issue shows up there as well. And I have now even two error cases, one temperature-inverse (which puzzles me even more). I attached the demo case, with the two .sof error case files:

- good at low temperature, bad at high temperature (DevKit_100702_V02.sof)

- bad at low temperature, good at low temperature (DevKit_100702_V03.sof)
