  • EgroupGB1Data_dbg[i]: 36-bits. Bits 33-35 are added by the gearbox: bit 35 indicates of the header is valid and bits 33-34 are the header (should be 01 if all is well). Bit 32 indicates if the data is valid.
  • LinkAligned: a single bit that indicates the alignment of the optical signal between Felix and optoboard
  • DecoderAligned_ila: should be 01 if uplink is aligned
  • EgroupUnscrData_dbg[0]: if you see values like 87*ffff fffff then the UPLINK polarity is inverted (it should be d78100000)
