old solution: cancel-out at DT and CSC track finder level confirmation by RPC in Global Muon Trigger maximum over-all efficiency is limited to the one of the RPC new solution: duplication allowed at track finder level DT/CSC cancel-out unit in GMT ghosts are reduced independent of RPC more robust some (tolerable) ghosting remains DT/CSC cancel-out unit

Global Trigger Boards PSB (Pipeline Synchronizing Buffer) Input synchronization (7 boards including GMT) GTL (Global Trigger Logic) Logic calculation (1-2 boards) FDL (Final Decision Logic) L1A decision (1 board) TCS (Trigger Control System Modeule) Central Trigger Control (1 board) L1A (Level-1 Accept Module) Delivery of L1A (1 board) TIM (Timing Board) Timing (1 board) GTFE (Global Trigger Frontend) Readout (1 board)
Global Trigger Logic Prototype Board GTL-6U Automatic chip design and setup procedure developed. Layout for a 20 channel GTL (4 , 4 isol. e/, 4 central jets, 4 fwd jets, SET, ETmiss, 8 jet multiplicities; other quadruplets can be connected alternatively for tests) has been finished and the board has been received end of October! Algo chips Condition chips
GTL-6U Prototype Schematics Design simplified, board tested by June 2003
New: HT Global Trigger Logic Board GTL-9U A redefinition of jet input groups has been done. The present best 4 central jets, 4 forward jets and 4 t-jets are kept. A new quantity HT giving the transverse energy sum of all good jets above threshold and 4 jet multiplicities have been added. The exact definition of how to calculate the jet multiplicities (h-range, thresholds) still has to be taken at the level of the calorimeter trigger.
GT Conversion Board A conversion board to be used later in final 9U-crate with GTL-6U prototype is ready. It contains also memories in FPGA’s to send simulated test data to the GTL-6U board.
Final Decision Logic FDL-9U FPGA design has started. Board available by June 2003. • Monitoring of all algorithm and L1A bits • Prescaling of all algorithms • Trigger Mask • 8 L1A’s in parallel for partition modes • Input of up to 64 technical trigger bits from PSB possible
Timing Board TIM-6U • TIM-6U The board contains a TTCrx chip and provides all timing signals for the GT crate. It will also be used in the Drift Tube Track Finder crates. An FPGA provides all necessary test functions to run the crate without the central TTC clock. It simulates also L1A requests for monitoring or to test the readout chain. The schematic design is finished. After deciding to go ahead as planned with mezzanine TTCrx solution, the layout is now finished. The final Timing Board will be 6U (previously 9U) and is expected for June 2003.
Central Trigger Control System Board TCS-9U • TCS-9U • Its functions and the input / output cables are defined. Design of schematics and the TCS chip is in progress. The board is expected by April 2003. • Trigger Partitions: The maximum number of subsystems is fixed (32). An agreement about the output to the DAQ Event Manager has been reached. The input format of Fast Signals is fixed. 4 coded bits per subsystem, sent as LVDS parallel data, and RJ45 connectors are proposed. The TCS board provides data for the ”TTCci” (new CMS-TTCvi). A L1A driver module to be used with the TTCci has been conceived.

FDL GT event record for Event Manager Subdetector partitions are combined in groups connected to a DAQ partition. Only 1 DAQ partition triggers at a time due to DAQ restrictions.

Global Trigger Setup Program Environment Task of GT Setup Program: Configure chips - via VME, JTAG (or from PROM) 2) Load registers, LUTs, memories - via VME Remarks: - For standard datataking, the trigger menu, setup of logic and thresholds from database (e.g. .xml) files, which are converted to HW format by custom or HAL device drivers. - For testing configuration files can also be loaded directly with Altera/Xilinx (e.g. MasterBlaster/ByteBlaster) hardware. - Run Control interfacing to be done. - JTAG programming not yet explored
