  1. Trigger Validation Board PVSS panels tutorial

  2. TVB components • 2 FPGA controls : • FPGA HCAL hadron trigger • FPGA EPPI electron , photon , pi0 , Global PI0 • Delay chips to be set for each FPGA • Look up tables for each FPGA (LUT) • Optical mezzanine • Temperature

  3. FPGA HCAL elements to be set • FPGA HCAL: • Ensure the HCAL+ECAL sum of corresponding pads • Card configuration : Which inputs are filled • Choice of signal front ( rising-falling) • Choice of the delay pipe line for trigger : setting of delay for each entry ( HCAL and ECAL) • PSSPD entries not used ( masked) • The phase adjustement to ensure full data transmission • Elements are set by default through recipees

  4. FPGA EPPI elements to be set • FPGA EPPI: • Select the highest electron, photon, pi0, global pi0 for each validation board candidate according to the PS/SPD pattern and ECAL energy. Parameters to be set : • Card configuration : Which inputs are filled • Choice of signal front ( rising-falling) • Choice of the delay pipe line for trigger : setting of delay for each entry ( PSSPD & ECAL) • The phase adjustement to ensure full data transmission • Elements are set by default through recipees

  5. The road to the TVB panel Main project CA1-EC1…: 2TVB /crate TVB number : (crate-(8(c-side), 15(A-side) )*2 + ( o(left) +1(right))

  6. Piquet materials - A panel summarize the setting and check their status in respect to the recipee : piquet summary • 2 panels allow to have more details on FPGA and are used for recipee update when channels masking is required • HCAL FPGA • EPPI FPGA

  7. Piquet summary (0) • Info générales Summary of settings and Status of front and delays Comparison to recipee Click to update the summary

  8. Piquet Summary : general info (1) General info on crate naming & location Recipee info When clicking a window of all files used in recipee appears TVB FPGA version of firmware To be check after TVB change

  9. Piquet Summary : Comparison to recipee(2) Check FPGA when red Settings are not the one expected in recipee Right part give more info: Comparison to the Recipee front settings Comparison to the recipee Delay setting. Also the FPGA HCAL (EPPI) panel can be consulted

  10. Piquet Summary: Comparison to recipee (3) Check the optical link configuration . More info in GOL panel. Red if not the recipee Configuration; reconfigure If persist check with L0 piquet Card & mezzanine temperature More information on temprature Panel . This information may not be reliable Check delay chip set FPGA phase if red. Reconfigure . If the error persist go to expert. More info on delay chip page In case of laser fault ( from the mezzanine) , check with L0 if data affected.

  11. HCAL PGA panel Give the information on the delay used channel per channel compare to recipee Green if ok BXid offset & idle are part of the recipee and checked in the summary panel

  12. FPGA informations panel: Mezzanine status panel All links should be green 12

  13. Temperature panels: 1. under the mezzanine 2. between FPGA A temperature of -0.5 means that all bits are on . Reading error of the temperature. To be fixed be expert . 13

  14. Delay chip page ( info ) Get the current delay setting Values expected by recipee Possibility of forcing delay chip reset

  15. Expert panel GOL mezzanine panels: 1. EPPI 2. HCAL Allow to change control on Optical links 15

  16. Delay chip and LUT panel: Read and change delay settings Value in use Reset delay chip Read from file Save new settings Reload the LUT manually 16

  17. FPGA informations panel: Mezzanine status panel All links should be green

  18. Triple Voting panels: 1. EPPI 2. HCAL Allow to read if Among the 3 register one Has changed To be efficient The read command Should be performed

  19. Recipes panel: By default the files are the one loaded for the configuration Will change the recipe For the cards Will redo the whole Recipe (10min)

  20. A TVB does not want to configure • Go to the Summary panel . Identify the faulty part • Call expert A TVB configure but L0 is complaining Check no faulty part in the summary channel If some call the expert.

  21. Trigger is too high or 0 • Check the Summary page • If faulty , reconfigure the whole crate • Trigger too high ask L0 the link with high rate • Identify the High or faulty link ‘ Electron ,photon .. Or HCAL using the Summary page and L0 info • Check the GOL status • Report to L0 & expert • The trigger is high coming from a faulty input to TVB) • Mask the fault input • Save the configuration ( next slide) • Next time the recipee will use this new configuration

  22. Mask an input channel to the TVB • HCALFPGA panel • EPPIFPGA 1. Get all 2. Mask the channel 3. Apply register 4.Update the recipee The next time the recipee is called the change will still be there

  23. Missing source complain from trigger people • Check Summary page • Check GOL status on HCAL or EPPI • Inspect the HCAL or EPPI FPGA settings /recipee (done automatically ) • Verify the input is not masked
