U.S. ATLAS HL-LHC Upgrade LAr Level 2 and Level 3 Managers Mailing List

[John Parsons <parsons AT nevis.columbia.edu>]

A few more comments:

p. 5 - maybe here (ie. early in talk) state that design is now for each 
LASP FPGA to handle 3 FEB2 boards (compared to earlier assumption of 4); 
clearly the number of FEB2 boards per LASP+SRTM is a major part of the 
system description

p. 7 - "CPPM for the LASP, which we test with write firmware for"?? 
This is not proper English

p. 9 - as I mentioned before, PDR was just for h/w
  - wording makes it seem 3 FEB2/LASP, but is actually per LASP FPGA, 
of which there are 2 per LASP

p. 12 - you give a "list" of h/w but do not actually say they have been 
successfully integrated (ie. what is the "message" of this slide?)

p. 13 - say PCB being submitted in April (if true)

p. 16 - you list ES&H contacts at 2 out of 4 institutions; either list 
all or list none

p. 17 - "Also had much faster (~4 month) delivery for recent sRTM v2 
board" is not a "world event"??  So it is out of place here.  This slide 
should deal ONLY with "world events".
Also, since v2 has in fact not been delivered, what do you actually mean 
to say?  (PCB order has not even been submitted yet)

p. 18 - this is too terse; provide some more info (you have plenty of 
space on slide, and plenty of time to talk about it)

p. 19 - again, PDR did not cover f/w
  - expand the text a bit

General:
 - maybe add a slide about new quotes, purchasing FPGA through CERN 
with lower prices, ...
 - the Breakout is quite long, so you could expand a bit the info on 
some topics to make it more complete, leave less time for questions, ...
