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

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

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)

• 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

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

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

Software under development

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

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
