3. Glt Algorithm The GltSim follows the hardware closely
It attempts to match the spatial and angular location
of calorimeter towers and DCH tracks. This results in 24 trigger lines
which are sent to the FcsSim to issue the L1Atime
The 9 primitives are:
A B Ap M E G X Y U
The Match and Combine Objects are:
AM BM ApM BMX EM
A* B* M* G*

5. Glt LUT Configuration The Glt is configured from the DB for more than
2 years now
L1GltConfigP_001
LineConfigP
New code to generate the lut is moved to L1GltOnline
and used by the online/offline(sim)
Online:
The Glt Lut is generated on the fly using the
Base lut bin file & the config pars from the DB->xtc
Offline:
Base lut is generated on the fly & the config pars
from the DB

6. Glt Lut Luts were tested on and offline the results are identical
Plan: have the base lut online generated on the fly as in the offline

25. Board Algorithm test We have two keys with PTD/ZPD configuration
The keys are
Main problem this is private code since commiting
Will create conflicts it depends on the L1DctTeststand
code

26. Tcl parameters
The input delays in the Glti are set with tcls parameters
and a switch depending if ZPD/PTD are going to be used
The time adjustment for the the DAQ window

27. Conclusion/Plan The code will be tested against the
Glt calibration in the teststand
Final 1 tick aligment of the Glt Blt inputs
