  1. XTRP Hardware Mike Kasten University of Illinois 2/24/00

  2. 2 XFT linkers CDF clock L1 calorimetry L1 muon L2 trigger SVT Data board transition module (x12) Clock/control transition module Level1 Request Clock/control board Track Data Data board (x12) 30° (2 wedges) Data boards (duplicates) 132 ns + 33ns clocks 12 data boards XTRP I/O The core XTRP System Internal communication

  3. XTRP Teststand #1: Pre-crate • Custom Backplane • Initial power-up • Boot PROM • VME emulation • Signals via Unidig Module • C code • Power measurement U of Illinois

  4. XTRP Teststand #1: VME crate • Successfully completed VME transactions • Write/Read registers • Load extrapolation RAMs • Benchtop accessibility & VME emulation were extremely helpful for initial debugging • This teststand will provide initial testing infrastructure for new VME boards

  5. XTRP Teststand #2: VME crate • VIPA-style Test Crate at U of Illinois • VME access • Write/Read registers • Load extrapolation RAMs • Multi-board system • Controller / TestClock / Clock Control / Data • Send clock signals from Clock Board to Data Board • Step data through Data Board (slow clock) • Software Development • DataBSim.java (Data Board simulator) • XtrpExpertPanel.java (Test engine)

  6. XTRP Functional Clock Test TestClock CLOCK TEST 132ns, 33ns, Sync Signals 132ns Clock Data Board Clock Board VME write (+Test Clock) 132ns, 33ns, Sync Signals

  7. Functional DataTestProcedure • Set up Data Board & Clock Board • Repeat N times: • Load XFT Simulation data into Data Board • Increment Data Board clock via Clock Board • Increment Simulator • Compare Data Board versus Simulator • Debug

  8. XTRP Functional Data Test VME write XFT Simulation Data VME write Test Clock Data Board Clock Board STEPPED 132ns, 33ns, Sync Signals VME read & compare to Simulation

  9. XTRP Teststand #2: VME crate • Data Board II is necessary • simple reroutes: ~100 • power supply pins (64 identical ICs ) • various • Mechanical compliance • Improvements (JTAG & buffering) • Data Board I lives on… • Completely Functional • Acceptable to use for B0 integration tests • Clock Control Board is OK (so far) • Corrections do exist: ~25 total wires • Relayout not planned

  10. XTRP Teststand #3: Wilson Hall • Multi-crate system • XFT CDF-style Crate • Test Clock / Clock Splitter / Controller / TRACER • LinkerTester • Linker / Output Modules • XTRP VIPA-style Crate • Controller / TRACER • Data Board • Clock Control Board • Much much more Software Development

  11. XTRP Tests DATA TEST >1,000,000 clocks error free Linker(2) Output Formatters VME write VME read & compare to Simulation Data transferred at full speed for 250 clocks VME read from Pipe FPGAs Linkertester Input Fifos Data Board CAL/MUON Data INPUT TEST >100,000,000 clocks errors: x000000 to xFFFFFF

  12. XTRP Tests VME write Output Fifos Linkers (2) Linkertesters (2) Data transferred at full speed for 10k clocks VME read & compare to Simulation Data Board Input Fifos >10,000,000 clocks error free

  13. XTRP Tests VME write Output Fifos Linkertester Data Board Data transferred at full speed for 10k clocks VME read & compare to Simulation Input Fifos Software under development

  14. XTRP Teststand #3: Wilson Hall • Data Board I • No more layout errors found • Data Board Transition Module - new board necessary • wiring corrections: ~5 • PCB footprint for Muon connector is wrong • Clock Board • No more layout errors found • Clock Board Transition Module - new board necessary • Errors found independent of testing

  15. Plan for New Hardware • Data Board II • Quotes requested, waiting for responses • Contract Assembler reviewing BOM • Target date for 1st DBII: April 1, 2000 • Data Board Transition Module • Want to connect to Muon & Calorimetry systems first • Target date for new TM: April 15, 2000 • Clock Board Transition Module • Need a new board for SVT & L2P integration • Target date for new TM: May 1, 2000

  16. Input Test Error x000000 to xFFFFFF Linker(2) Output Formatters Backplane Data Board Transition Module Data Board 3.3V LVDS Receiver 3.3V LVTH Latch xFFFFEF Error seen on only 1 out of 96 bits xFFFFFF
