T2 Software at IP5 that I've worked with

(Situation as of April 2010)


vfat_controller (no comments)

Latest monitor /data/T2/Monitor_developT2 (at vmepcS2B19-07) and also ~nturini/Software/Monitor

Xml input files

monitor xml files in /data/T2/XML_ConfigMonitor_IP5

vfat_controller xml files in ~nturini/T2/config

Vfat_controller xml schema at http://cmsdoc.cern.ch/cms/cmt/System_aspects/FecControl/binaries/misc/schema.xsd

Contains among other things VFAT lines

  • preamp/shaper settings, same for all
  • Control0,1,2,3 (control registers)
  • Chanreg1-128 (mask/calpulse/trimDAQ channel by channel)
  • Lat (latency)
  • Vthreshold1,2 (vt1=threshold, vt2=0)
  • chipid0,1=vfatID-16bit : low 8bits + high 8 bits

Xml file contains up to 688 VFATs, and in vfat_controller one can make changes to all the VFATs or to one at a time

  • automate to
    • speed up initial value setting
    • cut down error rate

I modified some of MirkoBerretti's scripts, producing methods to change

  • vthreshold1 = read from file: (VFAT ID,threshold)
  • chanregNNN= (chanregNNN OR 64) if Read from file: (VFAT ID,channel=NNN)
    • OR 64 is calpulse bit
  • easily modified too (not implemented now) :
    • OR 32 is maskChannel bit
    • AND 31=last 5 bits are trimDAQ value (look up vfat IID value in fileMonitor, set high trimDAQ for larger outer pads, pad IID=2...14)
    • For reference: If you set nonzero trimDAQ value, check that control3 AND 7=7 (or at least nonzero)

Scripts available here (see attachment) and on lxplus:

Scriptfile foThresholdsWrite-smallChanges.C contains three functions

  • WriteThreshold1Txt(fileVFATController,fileMonitor,fileOutTxt)
    • reads vt1 values & calculates vfat hex id
    • writes to fileOutTxt "0xHexId,Threshold" - one line per vfat
    • fileMonitor not used for output, doesn't affect fileOutTxt

  • WriteThresholdsXml(fileVFATController,fileMonitor,fileTxtThresholds,fileXmlOut,options)
    • reads vfatController file line by line, changes only vfat lines
    • if matching vfat id found in fileTxtThresholds, change vt1 to the threshold found on that line
    • options="" or "dropTheRest", the latter means drop any vfat not found in the text file
    • fileMonitor not used for output, doesn't affect fileOutTxt

  • WriteChanregsXml(fileVFATController,fileMonitor,fileTxtChannels,fileXmlOut,options)
    • reads vfatController file line by line, changes only vfat lines
    • options
      • ="dropTheRest", means drop any vfat not found in the text file
      • ="zeroCal", means to set in all chanregs of all vfats the calpulse bit off (test chanreg&64)
      • ="setCal", means set the calpulse bit to 1 for any (vfat,channel) found in the text file AND set to 0 for all other channels
      • if both zeroCal and setCal given, zeroCal takes precedence
      • if both zeroCal and dropTheRest given, the latter has no effect since the text file is not read
    • fileMonitor not used for output, doesn't affect fileOutTxt

Call functions like this:

  • start root: [bash%] root
    • tested with root v5.18 at vmepcS2B19-*
  • [0] .L scriptfile.C+
    • loads & compiles scriptfile.C
  • Function1(param1,param2,""=default param3)
  • Output text or xml file overwritten without warning
