T2 Software at IP5

(Situation as of April 2010)

Software

vfat_controller (no comments)

Latest monitor /data/T2/Monitor_developT2 (at vmepcS2B19-07)

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
    • 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:
