Introduction:
As can be seen from the figure below, the focal point for much of the
Level 1 trigger information is the XTRP module. The purpose of the XTRP
is to receive tracking information from the XFT and distribute the tracks
and/or information derived from the tracks to the Level 1 and Level 2 trigger
subsystems. After receiving the tracks from the XFT, signals are sent to
the Level-1 Muon system (L1MUON), the Level 1 Calorimeter trigger (L1CAL),
and the Level 1 Track Trigger (L1TRACK). The tracks are also put into a
pipeline and upon receiving a Level 1 accept are sent to the Level 2 processor.
The tracks then sent to the Level 2 processor and the silicon vertex trigger
(SVT).
The purpose of the XTRPSim package is to exactly duplicate the functionality
of the XTRP module at the hardware level. Data is inserted into the XTRPSim
in the same format as the XTRP module and clocked through an exact replication
of the XTRP boards. Output banks are then created (with description "Simulated
Trigger Bank") which should exactly match the real banks.
Code
The following classes have been designed and coded (package XTRPSim):
-
DataBSim.cc
- Simulates the functionality of the Data Boards. Calls SimCalMuon to work
with lookup maps.
-
SimCalMuon.cc
- Simulates the calorimeter and muon lookup functions and bit OR-ing, etc.
-
TrackTrigger.cc
- Simulates the functionality of the track trigger board.
-
XTRPMatchboxData.cc
- Storable_object used for TCMD and TL2D output.
-
XTRPSimModule.cc
- Driver module. Reads in data, calls necessary classes, clocks data, creates
output.
-
xtrpMap.cc
- Accesses database and prepares for lookup map generation. Calls xtrpMapGen.
-
xtrpMapGen.cc
- Does the actual lookup map generation.
Input and Output
The XTRPSim package inputs track data either from
XFLD
or
XTRD
D-banks. The parameter "readinXFLD" in the talk-to determines which bank
is read in: XFLD data, readinXFLD = 1; XTRD, readinXFLD = 0. Normally XTRPSim
should be run in the default mode and pull input from the XFLD D-banks.
For diagnostic purposes, it is sometimes useful to pull input from the
XTRD D-bank. The parameter "standalone" in the talk-to determines if real
(standalone = 1) or simulated (standalone = 0) XFLD is read in. Normally
XTRPSim should be run in the default mode and pull input from real XFLD
D-banks.
XTRPSim produces in output the following bank and storable_object:
