Slice Test DAQ Software what we did in Florida, and what problems may be lurking beneath the surface

and what problems may be lurking beneath the
surface

Event Builder Input

• GenericFED class encapsulates XDAQ communication
  between detector-dependent software, event
  builder readout unit (Ichiro, Rick)

Event Builder w/Trackfinder

• Only need an EventReadergetNextEvent() routine
• Writing a routine which reads (destructively) the
  Sector Processor FIFOs, stores in memory, and
  parses events
• File-reading version already exists
  (Holger/Darin)
• Just need to merge with the HAL interface
• After that's done, the XDAQ-ification is easy.

Event Builder Output

• Format is ORCA-readable (G. Bruno)
• Event Header
• Readout Unit Header (Chamber data DCC)
• FED Header (DDU)
• DDU data
• FED Trailer
• Readout Unit Trailer
• Readout Unit Header (Trackfinder crate)
• Trackfinder data
• Readout Unit Trailer
• Event Trailer

5
Issues Event Synchronization

• Right now, the Event Builder assumes the events
  all come in the same order from all inputs
• Not always the case events can get lost
• We need to make some phony TriggerInterface for
  the EVB which tells it which trigger number to do
  next. Maybe based on the level 1 accepts in the
  chamber data?

Peripheral Crate Controller

• Replaces C routines in cfeb_control
• Verified at test crates in Fermilab, UCLA,
  Florida
• Sends same signals to VME as cfeb_control
• Practical Advantages
• Sends start and stop signals to boards
  automatically
• User doesn't need to do by hand
• Can keep many crates boards in memory
  simultaneously
• Configuration done in XML (Alex)
• Want to hear Valeris experience with using it
  for slow control

XDAQ Crate Control

• Only three buttons
• Configure
• Enable
• Disable

Issues Winning market share

• Cfeb_control is a huge GUI with a button for
  almost every subroutine in the system.
• Do we need to compete with that?
• How else can we get the electronics experts to
  use (and develop and maintain) the new code?

11
Issues Maintaining Crate Code?

• I claim our code makes the correct VME calls for
  five kinds of boards.
• I dont claim to understand any boards VME
  calls.
• Who can provide?
• Meaningful names for all those hardcoded register
  and address numbers?
• All boards
• Cleanup of vestigal code?
• Especially ALCT
• This code will be in CMS longer than many of us!
• It should correspond explicitly to the hardware
  manuals
• A HAL rewrite may be in order someday

Slice Test Software Summary

• XDAQ/C Crate Control ?
• Event Data Structure ?
• Including Sector Processor data ?
• Expect to be done soon
• Combined Event Building ?
• Just need to deal with event synchronization
