Glt Algorithm

The GltSim follows the hardware closelyIt attempts to match the spatial and angular location of calorimeter towers and DCH tracks. This results in 24 trigger lineswhich 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*

Glt LUT Configuration

The Glt is configured from the DB for more than2 years now1) L1GltConfigP_001 2) LineConfigP New code to generate the lut is moved to L1GltOnlineand used by the online/offline(sim) Online:The Glt Lut is generated on the fly using theBase lut bin file & the config pars from the DB->xtcOffline:Base lut is generated on the fly & the config parsfrom the DB

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

Board Algorithm test

We have two keys with PTD/ZPD configurationThe keys are Main problem this is private code since commitingWill create conflicts it depends on the L1DctTeststandcode

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
