(r3) AMC13RawDataAnalysis < BUCMSPublic

New analysis code being developed for 2014 data format

New code is being developed by Daniel Arcaro with help from Eric Hazen and Dan Gastler to analyze the new/final data format documented here: AMC13CommonFirmwareProposal.

A preliminary API is documented below. Three classes are foreseen:

Class	Description
FedEvent	one event fragment as received from an AMC13 in response to a single L1A
FedAmc	Payload for one AMC
FedBlock	internal block structure of event fragment

Each class is documented below:

Class FedEvent

Function	Description
`FedEvent( uint64_t* data, size_t size)`	Constructor using raw data
`EvN()`, `BcN()`, `OrN()`	Access Event, Bunch and Orbit numbers from event header
`vector amc`	Vector of 1...12 FedAmc objects representing AMC payloads
`CalcSize()`	Size calculated from structure (should match total word count)
`CRC()`	CRC16 from event trailer
`CalcCRC()`	CRC16 calculated from event data (should match `CRC()`)

To Do List

Bugs

In FedEvent::PreParse the expression if(GetNAMC() > 0 || GetNAMC() < 13) is always true. I think you mean to use && instead of ||.
In FedEvent::PreParse there are two possibilities for size: a) 2 and b) 4...14. It should throw an exception if any other value is passed. The comments should reflect this.
Add a doxygen configuration file and "doc" target to makefile so one can do 'make doc' and get the doxygen output.

New Features

Check for consistency of LMSEPVC bits through an entire event
- MS should be "10" for first block, "11" for intermediate blocks, "01" for final blocks.
- C should be 1 when MS="01".
- EP should always be "11" I think
Check Blk_No, AmcNo, BoardID in block headers for consistency throughout event
Add option to dump entire AMC payloads
