Mysteries:

• set_location_assignment PIN_AC7 -to RGB_LED_SDI -disable -comment "vrefb3an0 PIN_AC7"
• set_location_assignment PIN_L26 -to VME_A[29] -disable -comment "vrefb6an0 PIN_L26"
• D8 - DIFFIO_TX_T56 - "VME-DIG-3.3V"
• quartus messages about many pins:

Critical Warning (12888): Cross talk of LVDS Pin eSATA_TRIG from SE IO is too high. Reassign or move one or more of the following SE I/Os pins location and re-run the analysis again.  Please refer to the guideline from the Knowledge Base solution ID: rd10102013_979 and ensure the total % of crosstalk for the following SE I/O pins does not exceed 100%.
    Info (12899): SE I/O from the bank contributed to 99.18% of the margin due to SSN
    Info (12900): SE I/O MAC_SDA contributed to 9.19% of margin due to crosstalk
    Info (12900): SE I/O MAC_SCL contributed to 7.02% of margin due to crosstalk
    Info (12900): SE I/O VME_BR_out[0] contributed to 0.46% of margin due to crosstalk
    Info (12900): SE I/O VME_D[27] contributed to 2.75% of margin due to crosstalk
    Info (12900): SE I/O FP_LED_LATCH contributed to 10.17% of margin due to crosstalk
