2020-07-19 Notes
GENERAL:
Following ATLAS guidelines for firmware development?
- Is the firmware in a repository? All TDAQ developers are supposed to have access.
- Are they using HOG?
- Do they have a coding style document
TGC
- URAM are 4096x72 (288k). in VU90 there are 960.
- BRAM are 512x72 (or 1024x72). in VU90 2048 (1024)
- Trigger path
- TGC-BW wire reconstruction
- 92 "units" per SL
- 4x URAM per Unit = 368 URAM
- TGC-BW strip segment reconstruction
- 88 "units" per SL
- 1x URAM per 2 units = 44 URAM
- Strips+wires combined using BRAMS (not yet developed)
- TGC+NSW combined using BRAMs (not yet developed)
- TGC-EI/RPC/Tilecal combined using BRAMS
- TGC-BW wire reconstruction
- DAQ path
- 4 BX per L0A
- 6700 ch bitmap convert to hits (40 hits/BX for PU=200)
- convert in parallel
- prototype for 32 channels implemented
- Missing
- All interfaces
- TTC
- Control/monitoring
No power estimates. Resource estimates sketchy.
RPC
Algorithms described fairly well but no power or resource estimates.
Review 7/22
- "Design ready"? If so, where is it? Can we look at the design files?
- Over-temp, over-current shutdown on blade?
- Sensor access by SoC
- Power-up and power-down (SoC startup and shutdown)
- Can recover from SoC boot failure?
- HW slide 10 - where are chip-to-chip transceivers?
- Slide 11 - only one reference clock freq?
- Power control - can SoC shut down blade
- How to set MAC / IP address?
- Take care of level shifting and power zones in I2C network
