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
AMC13Block	internal block structure of event fragment
FedAmc	Payload for one AMC
FedEvent	one event fragment as received from an AMC13 in response to a single L1A

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()`)

For preliminary HCAL data format used through 2013

I've developed a simple unpacker and some command-line tools to dump and error-check the data from the VME system or the new MicroTCA system (data formats are a bit different). The original version was developed as a CMSSW job "EricDIM" TWiki page.

To get the tools from our svn and build them:

  $ svn co svn://cms1.bu.edu/Eric
  $ cd Eric/RawAnalysis
  $ make
  $ ./dump_DTC.exe
  usage:  dump_DTC.exe [options] file_name
    -e (check for sequential EvN)
    -h (check for uHTR EvN)
    -v (verbose)
    -d 
       1=DTC header 2=uHTR headers  3=uHTR payload
  $

If you run e.g. ./dump_DTC.exe -h dump1.dat it will check the file dump1.dat for EvN, BcN and OrN errors. The data format is documented here. ("HCAL Upgrade Data Format", latest version).
