  1. M. Noy 21.05.2004 Progress Report

  2. Test Bench Architecture • Updated Architecture • Improved modularity, and test separation through ABC • Preprocessor reduced in complexity • Added automatic report generation framework • Hierarchical web pages for results and log info. • Added crate detection mechanism • “One click” detection of crate contents • Previous sequence architecture now loops over FEDs (detected) in crate. • Now been placed in the Fed9U project

  3. TBTestABC • Has 4 pure virtual functions • Initialise(), Exercise(), Analyse(), Finalise() • Called in sequence during test exe. • Fin. Is like destructor, and is called in abnormal term. • Redundancy here, can use class destructor... • Static Instantiator provides handle to TB • Constructor is passed reference to test param. “bag” • User variables • FED crate entry, BA, SN of DUT • Ref to component status container -> results • Results manager -> results dir struct • req. FED SN, (request submitted to savannah)

  4. TBTestABC contd. • Test Generation Script • Produces class skeleton • .hh, .cc, function stubs, instance macro • Test Parameters File (.tpf) • Handle for LUT (default can be changed) • Additional Makefile include search, link search, and libs • Key for the PreProcessor • tests without a .tpf file are ignored

  5. Report Generation • Fed9UComponentStatus ABC • Each component needs a status class inheriting from this • Implement method: • virtual void fillReportElement(Fed9UReportElement &)=0 • Interface to the Fed9UReportElement • Uses component type + Fed9UAddress for unique ID • Fed9UReportElement • Interface between Comp. Stat. and Fed9UReportGenerator • Report is made from multiple elements, one for each component • Containers are standard, report generator parses the component status container, generating ReportElements, -> Report • Invoked after each FED is tested

  6. ResultManager • Manages TB output directories • FED Ser No. key for dir struct. • Maintains test instance no. • Allows consistency for repeated tests • Helps web page hyperlink management • Used to manage local test logging • TBD, but will simply use new instance of existing TB system log (has modified streamers for time stamp, banners, etc.) • This log will have link on FED specific results page • Similar to existing system/error log.

  7. Test Status • Written a TrimDAC test • Test Module • Fed9UTrimDACStatus • (:public Fed9UComponentStatus) • Used to test report generation • Uses ROOT fitting algo. • But have seen problems traced to root libs that cause system to behave unreliably • Slowed progress -> possible alternative...? (cernlib? suggestions welcome) • Demostration will be prepared for week of 7th June

  8. This week... • Atomicity in BLT readout (or not) • JF, LM + MN tried readout with 2 FEDs • Problems seen when one FED reads out + 2nd FED polling for events. • Traced to conflicts between logically concurrent use of block/single accesses to the SBS • Solved using IPC semaphore • Makes event loop in Fed9USupervisor atomic • Then saw new problems with event corruption. (Wed.) • Firmware version made no difference • Switched FED off -> yesterday readout ~100000 events with no problems • ?temperature -> needs study
