Context :
Normally, all data of a snapshot must be write into memory buffer before the next snapshot. By consequence when a new snapshot occurs, WF fifo should be empty.

Problem :
During the exploitation, an errors can occurs and desynchronise the snaphot controller and the fifo.

Solution ?

• Synchronised fifo "reset" with the waveform controler.

  The problem is solved only if it's FIFO that is desynchronized.

• Checked consistency of TIME field in the memory buffer.

  If one element of the WaveFormPicker is desynchronized, the software can detect the problem. If it's a "data shift" into the memory, the Time Field should be corrupt.
  And if it's a "time shift", the date in the Time Field should not be coherent.
