Check the correctness of DCB data GBTxs to Pathfinder COMET connectors mapping #4

Closed yipengsun closed 5 years ago

yipengsun commented 5 years ago

@manuelfs I have release another debug mapping (see 1) for DCB data GBTxs (U[1-6]_IC2) -> Pathfinder COMET_{A,B}_J{1,2}. Please help me check the correctness of the mapping (maybe with the help of some undergrads).

Now the only remaining task to generate a full COMET -> DCB mapping is to connect these 2 mappings together.

After lots of arguing about even/odd/left/right, we have determined a rule for matching pins for J6:

The even side of J6 on the COMET has Pin N corresponding to Pin N-1 on the DB’s J6. The odd side of J6 on the COMET has Pin N corresponding to Pin N+1 on the DB’s J6

There are also 6 pins that have their net name switched from N to P or vice versa which are located int the wiki.

Note that on the DCB -> Pathfinder side, we don't expect any pin-flipping shenanigans.

Also, you should update your findings at 1. Please try to following the existing table format.

@LegyPlegy @SummerLeaves wonderful job. I didn't check it until now. Thanks a lot!
