CMS Week, Sep C.-E. Wulz3 New layout of Global Trigger 9U Crate

CMS Week, Sep C.-E. Wulz4 Global Trigger Logic Prototype Board GTL-6U 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,  E T, E T miss, 8 jet multiplicities; other quadruplets can be connected alternatively for tests) has been finished! 1020-pin Altera FPGA 20k400E not yet included. The layout of a conversion board to be used later in final 9U-crate is ready. It contains also memories in FPGA’s to send simulated test data to the GTL-6U board. A decision on a redefinition of jet input groups has been taken. It was decided to keep the present best 4 central jets, 4 forward jets and 4  -jets and jet multiplicities for different E T thresholds. A new quantity H T giving the transverse energy sum of all good jets above threshold has been added. The exact definition of how to calculate the jet multiplicities (  -range) still has to be taken at the level of the calorimeter trigger. More than 8 values could be necessary.

CMS Week, Sep C.-E. Wulz7 GTL-6U Prototype Schematics Design simplified, board available by June 2003

CMS Week, Sep C.-E. Wulz8 Final Decision Logic FDL-9U FPGA design has started. Board available by June 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

CMS Week, Sep C.-E. Wulz9 FDL-9U

CMS Week, Sep C.-E. Wulz10 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. The layout is in progress, decided to go ahead as planned with mezzanine TTCrx solution. The final Timing Board will be 6U (previously 9U) and is expected for June 2003.

CMS Week, Sep C.-E. Wulz11 TIM-6U

CMS Week, Sep C.-E. Wulz12 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 Trigger Partitions: The maximum number of subsystems is fixed (32). An almost final 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.

CMS Week, Sep C.-E. Wulz16 Global Trigger Setup Program Environment Task of GT Setup Program: 1)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
