5. Jim Brooke, 10 th May 2006 Emulator Resources Jim Brooke (25%), Rob Frazier (50%), Greg Heath(25%), Maria Hansen (50%) Status Main processing algorithms written and most ‘glue code’ complete 1st version ‘digis’ committed to DataFormats/GctDigi Integration with CMSSW underway Plans Produce stable code for validation Validate with Monte-Carlo Validate firmware against emulator Milestones June 06 : 1 st release for validation

6. Jim Brooke, 10 th May 2006 Control & test GCT Driver HAL-based API for hardware access Object model of the hardware VME64x slave in each FPGA Register read/write Buffer access LUT access Python wrapper Test scripts Command prompt… Test Scripts Basic hardware/firmware tests Link tests Initial integration tests In-situ tests use Trigger Supervisor GCT Controller XDAQ wrapper around Driver Functionality : Initialise system Load LUTs Report system status Run tests In-situ debugging Capture event record External interfaces : Trigger Supervisor Config DB GUI Embedded python interpreter Mainly used for initialisation

7. Jim Brooke, 10 th May 2006 Control & test (Source) Source Card Driver Based on existing code at Imperial College Need to move this to CMS trigger repository Allows standalone testing Serdes loopback/test ctrl & buffer readout Read serdes status Pattern generation Input capture buffer readout Include python wrapper Allows main GCT controller to run a script to eg. start test mode Source Card Controller XDAQ application around Driver SOAP interface to GCT Controller Functionality Retrieve captured data for in-situ readout of RCT output

8. Jim Brooke, 10 th May 2006 Control & test Resources Rob Frazier (100% from 1 st July), Jim Brooke (20%) Status Work due to start after 5 th June Adapt code from old project to the new hardware Many of the design problems solved Need to encapsulate new hardware/firmware structure Write new routines for different firmware (eg buffers) Integrate with TS, Cond DB Work started in old software Milestones Oct 06 : ready for Source/Leaf/Concentrator integration Feb 07 : ready for Electron trigger integration

9. Jim Brooke, 10 th May 2006 Monitoring Requirements Verify hardware processing Online/offline DQM Diagnostics Record to Cond DB GCT Monitor (library) Several applications Standalone debugging HLT farm Trigger online farm (?) Offline DQM Input is GCT event record From DAQ or GCT controller Contains all inputs and outputs Functionality Hardware verification Run on all triggers… Compare emulator with hardware Verify link checksums Produce as much diagnostic output as possible! DQM Use various subsets of triggers Occupancy plots of all objects by , , E t, module, crate Compare trigger data with full detector data etc… Send summary information to Cond DB

10. Jim Brooke, 10 th May 2006 Monitoring Resources Alex Tapper (50%), Jim Brooke (20%), Greg Heath (25%) Status Start work after 5th June (Emulator release) Run emulator in CMSSW DQM framework Add diagnostic functions Add histograms etc. Include functionality in line with hardware schedule Integration with RCT, electron triggers, jet triggers Some discussion required Standalone tests Milestones Oct 06 : ready for Source/Leaf/Concentrator integration Feb 07 : ready for Electron trigger integration Jun 07 : ready for Jet trigger integration
