51The DDL file starts with common header which size and structure is standartized and mandatory for all detectors.
d3da6dc4 52The 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.
53For HMPID the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13.
54
55Common header might be followed by the private one although HMPID has no any private header, just uses the common one.
56
da08475b 57Single HMPID D-RORC (with 2 channels) serves a single chamber so that channel 0 serves left half (PCs 0-2-4)
58 1 serves right half(PCs 1-3-5)
d3da6dc4 59
60So the LDC -chamber-ddl map is:
da08475b 61DDL index 0 -> ch 0 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601
62DDL index 2 -> ch 1 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603
63DDL index 4 -> ch 2 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605
64DDL index 6 -> ch 3 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607
65DDL index 8 -> ch 4 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609
66DDL index 10 -> ch 5 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b
67DDL index 12 -> ch 6 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d

69HMPID FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows.
da08475b 70Each DILOGIC chip serves 48 channels for the 8x6 pads Channels counted from 0 to 47.
d3da6dc4 71
72The mapping inside DILOGIC chip has the following structure (see from electronics side):
da08475b 73pady
d3da6dc4 74
da08475b 755 04 10 16 22 28 34 40 46 due to repetition in column structure we may introduce per column map:
764 02 08 14 20 26 32 38 44 pady= 0 1 2 3 4 5
773 00 06 12 18 24 30 36 42 addr= 5 3 1 0 2 4
782 01 07 13 19 25 31 37 43 or vice versa
791 03 09 15 21 27 33 39 45 addr= 0 1 2 3 4 5
800 05 11 17 23 29 35 41 47 pady= 3 2 4 1 5 0
d3da6dc4 81
82 0 1 2 3 4 5 6 7 padx
83
8410 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure.
85DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10.
8624 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes.
87Rows 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
88 and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number.

90HMPID raw word is 32 bits with the structure:
91 00000 rrrrr dddd aaaaaa qqqqqqqqqqqq
92 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)
