50 : The DDL file starts with common header which size and structure is standartized and mandatory for all detectors.
51 : The header contains among other words, so called Equipment ID word. This unique value for each D-RORC is calculated as detector ID << 8 + DDL index.
52 : For HMPID the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13.
53 :
54 : Common header might be followed by the private one although HMPID has no any private header, just uses the common one.
55 :
56 : Single HMPID D-RORC (with 2 channels) serves a single chamber so that channel 0 serves left half (PCs 0-2-4)
57 : 1 serves right half(PCs 1-3-5)
58 :
59 : So the LDC -chamber-ddl map is:
60 : DDL index 0 -> ch 0 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601
61 : DDL index 2 -> ch 1 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603
62 : DDL index 4 -> ch 2 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605
63 : DDL index 6 -> ch 3 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607
64 : DDL index 8 -> ch 4 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609
65 : DDL index 10 -> ch 5 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b
66 : DDL index 12 -> ch 6 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d
67 :
68 : HMPID FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows.
69 : Each DILOGIC chip serves 48 channels for the 8x6 pads Channels counted from 0 to 47.
70 :
71 : The mapping inside DILOGIC chip has the following structure (see from electronics side):
72 : pady
73 :
74 : 5 04 10 16 22 28 34 40 46 due to repetition in column structure we may introduce per column map:
75 : 4 02 08 14 20 26 32 38 44 pady= 0 1 2 3 4 5
76 : 3 00 06 12 18 24 30 36 42 addr= 5 3 1 0 2 4
77 : 2 01 07 13 19 25 31 37 43 or vice versa
78 : 1 03 09 15 21 27 33 39 45 addr= 0 1 2 3 4 5
79 : 0 05 11 17 23 29 35 41 47 pady= 3 2 4 1 5 0
80 :
81 : 0 1 2 3 4 5 6 7 padx
82 :
83 : 10 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure.
84 : DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10.
85 : 24 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes.
86 : Rows are counted from 1 to 24 from top to bottom for right half of the chamber (PCs 1-3-5) as seen from electronics side, meaning even LDC number
87 : and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number.
88 :
89 : HMPID raw word is 32 bits with the structure:
90 : 00000 rrrrr dddd aaaaaa qqqqqqqqqqqq
91 : 5 bits zero 5 bits row number (1..24) 4 bits DILOGIC chip number (1..10) 6 bits DILOGIC address (0..47) 12 bits QDC value (0..4095)
