John Hobbs (at Stony Brook),
Bill Lee, Meenakshi Narain, Axel Naumann,
Georg Steinbrueck (at ColumbiaU), Wendy Taylor,
Silvia Tentindo-Repond,
Horst Wahl (at FSU)
Minutes:
- status of motherboard [Ulrich Heintz]
- motherboard:
- layout complete, sent to manufacturer last Monday, back mid October
- expect first prototype to be assembled by 1 November
- evaluation about one month, revison if necessary;
- open question: replace Universe2 chip by FPGA?
(note Universe is 5V chip, may be discontinued);
(decision by 10/20?)
- expect final prototype by Feb 2001
- cost 3k$ prototype, 1.5k$ production boards
- LRB/LTR (link receivers and transmitters):
- prototypes in hand, being evaluated;
- known changes:
- error correction
- FIFO expensive -- bigger FPGA including FIFO?
(requires larger FPGA -- Acex? --
decision 10/20)
- cost $540 LRB (of which $360 FIFO)
$182 LTB
- FRC [Hal Evans]
details about FRC schedule can be found
here
- STC [Meenakshi Narain]
- prototype I:
- FPGA code for STC channel done
Altera Flex or Apex? (decide 11/1)
- FPGA code for control logic 11/1
- FPGA code for PCI 11/1
- schematic 12/1
- layout 1/1/01
- PCB + assembly 2/1/01
- evaluation ?
- prototype II
- Altera or Xilinx?
- 8 channels in large Xilinx chip?
- cost:
at present very uncertain;
note Xilinx Virtex $1500
- TFC [John Hobbs]
- status and schedule
- design is nearing completion.
- prototype order expected: Nov. 14
- prototypes expected back to us : Nov. 30 (minimal assembly)
- TFC standalone tests: Dec.1 - Feb. 28
- system testing ????
- production order placed ????
- TFC Budget situation
(first number is budget, second spent, third remaining purchases)
- Shop (design, etc): $90k -- $22k -- $50k
- Prototyping + production: $290k -- $40k -- $150k
- Originally Fermilab: $0k -- $43k -- ???
- TOTAL $380k -- $105k -- $200
We estimate having roughly $75k left.
The prototyping and production costs are for the TFC
daughtercard only and do not include the motherboards
- discussion
- overall, we are about three months behind schedule
- had originally foreseen 60 days for integration tests
after 2nd prototype, starting in Feb 2001,
now will have 1st prototype in Feb.
-- try to do as much of integration tests with 1st prototypes
as possible
