Presentation Transcript

  1. Control of the Global Muon Trigger Tobias Noebauer Ivan Mikulec Marc Magrans de Abril Christian Hartl Thomas Themel Gregor Kasieczka

  2. GMT takes 16 input muons, reduces to 4 “best” sorted muons to send to GT GMT hardware is not static FPGA firmware implements functions Registers in firmware to change configuration LUTs used to implement constant-time functions Recapitulation from yesterday

  3. GMT Configuration GMT is configured from central cell with a subsystem key Configuration details are fetched from database Implements standardized configuration operation as required by central cell

  4. GMT Configuration DB

  5. Configuration Panel

  6. LUT Generation Functions defined by C++ functions in GMT emulator. GMT emulator runs in offline software framework CMSSW (later) Need to launch from within TS to generate lookup tables for loading to in hardware. Additional parameters from GMT_SOFTWARE_CONFIG table

  7. Parameters Panel

  8. Monitoring Panel

  9. Test Panel

  10. Pattern Testing Load inputs into simulation memories Capture output in spy memories Compare expected outputs to emulator

  11. Run Settings Panel Deal with small configuration variations that would require too many keys while still keeping provenance information.
