CRU Weekly Meeting

Wednesday 14 Feb 2018, 11:00 → 12:00 Europe/Zurich

CERN

 

• 10G PON
• GBT
  • Question : why reordering when ATX_PLL is not used and not otherwise (use_ATX_PLL)
• DCS
• PCIe
• Integration
  • Question : in preint what are the branches preint8, preint8-noice and debug (>6 months old)
  • Adaptation for V2 firmware :
    • New top_pcie40_v2
    • Now for PCIe, but 2 ref clocks, 2 resets ...
    • Different PLL
    • ...
• Simulation
• Production
• Task list (to be discussed)
  • Merge preint in pcore and use QSF for project description (OB)
  • Remove libraries in GBT core, ctpemu, cru_dummy_logic, onu_core, onu_user_logic, pciedma. For those, use component declaration and/or package
  • Get some documentation on the TTC-PON and ONU core (electronics group documentation? What was modified or not?)
  • Establish a list of modification in the GBT (file modified and for which functionnality)
  • Update of the specification and the requirement documentation
  • Regroup functionnalities :
    • GBT related
    • TTC related
    • DCS related
• AOB

10G PON

(Mazsi)

• Design was tested with CRU and an evaluation board for the PLL (the one on CRU was not used)
• Seems to be working
• Friday the PLL on the CRU were configured correctly
• We have to move to the new PLL that are in the CRU to make new measurement, or use the internal PLL (measurement have to be done)
• Any commit forecasted -> yes hopefully today

 

GBT

(Erno)

• Was focused on the test the new Calcutta boards
• The GBT-test project is used for testing the hardware only
• Last week, new GBT project with the use the new git
• PiPPo: what about the PLL calibration script (in CRU test repository). Unfortunately TPC developped its own
• Channel mixing due to the ATX_PLL :
  • not sure we will use it, so not applied all the time because it messes up the front panel.
  • Decision to be taken after measurement → we will keep only one possibility

 

DCS

(Pippo)

• Script were fixed by Tuan, work still on going for I2C PLL scripts, also minipod scripts were fixed

 

 

PCIe

(Pippo)

• No big news, working on the simulation

 

 

Simulation

(Olivier)

• Further simulation has been done on datapath wrapper, this part quite understood yet, testbench may be further refined later on

 

 

Integration

(Olivier, all)

• Library names removal done in many modules, use of verinfo fake for modified libraries
• Usage of QSF was extended
• Stitching of preint to core (done in the afternoon)
• Tivadar whishes that we target to have a CRU V2 firmware today or tomorrow in order to test with Jean-Pierre during this end of week.
  • It does not seems to be realistic because of various issues (vhdl adaptation, TPC tests, ...)
  • We can ask Jean-Pierre to leave a board here, but in that case we have to be sure to use it for testing.

 

Production

 

• Very first days of march, first CRU V2 will be available
• A few more by mid march
• Then more will arrive by end of march no plan to distribute them yet

 

 

Documentation

 

• During march Tivadar will take care of updating the documentation with Erno
