<pre>Ran standard, 33ns and finder-to-linker tests on all XFT crates. 
ALL boards PASSED. (Note #23 always fails the 33ns test in 
finder#08.  This is a known feature of the diagnostic test 
design. It is not relevant for the data-taking design.) 
 
Testing spare linkers in b0xft05 slots 4-12. 
--------------------------------------------- 
1 spare from rack on second floor (#15) 
 
2 spares from OSU with a special VME design- these boards 
were dropping the CONFIG-DONE bit, which caused problems with 
the COLDSTART checks.  Altera said there was no reason this bit 
should stay high forever and that it was not a problem.  
Therefore, in the special VME design for these boards only, we 
latch the CONFIG-DONE bit immediately it goes high, which it does 
if the boards have been sucessfully downloaded.  I need to 
remember to update the hardware database field for the  
VME design version number for these boards. 
 
2 "spares" from b0xft06.  One is #30 aka the prototype 0 board!! 
It needs to be tested before becoming an approved spare. 
The other is #12 which rarely drops bit 4 in IF4 RAM0.  This 
is a good candidate for the new XFT teststand.  Maybe looking at 
the timing on an oscilloscope and changing the timing slightly 
would fix the problem....#12 will be swapped out again 
at the end of the day. 
 
The last time we swapped in a spare was July 2001!!!!!!!

<pre>Board #30=p0 had a stuck bit on IF4 Ram 0 bit 9. 
This was always high.  Looked at the board, Roberto looked 
at it as well.  It may now be fixed - test next time. 
Otherwise, board passed 5000 events of finder-to-linker test. 
 
Board #12 removed since we know this one has a rare problem in 
IF4 RAM0 bit 4, which is sometimes lost.  Didn't see the  
problem in finder-to-linker test. 
 
Boards #24 and #3, in slots 8 and 10 in b0xft05, have VME design 
version 6!  Have updated the hardware database for this.  All 
other boards have version 5.  The error message from run control 
looks clear enough that we should be able to figure this out 
in future if we move one of these boards and forget... 
 
Crate b0xft05 
Slot 	Serial number 
---------------------- 
4	26 	(as before) 
6	23	(as before) 
8	24	spare 
10	03	spare 
12	15	spare 
 
Boards #14, #13, and #21 are in the spare rack on the 
second floor.  They worked perfectly since July 2001 so  
they are good spares for the future.

<pre>Ran finder input capture test for 20K events.  Aside from the  
usual rare-zero problem, the B0 signal from the ansley cable  
appears to come in one event late intermittently for XFT04  
slot 15 and Slot 17.  The problem was fixed by replacing 
XTC cards in B0COT15 slot 12 and B0COT16 slot 14. 
The results of the input capture test is shown below:

and finder-linker (ttbar events) tests on all spares. 
 
SL1/3 #005: passed (now in B0XFT04 slot 6) 
 
SL1/3 #010: passed (now in B0XFT04 slot 8) 
 
SL1/3 #027: passed (now in B0XFT04 slot 10)

SL1/3 #020: passed (in second floor B0 cabinet) 
   
SL1/3 #006: passed input capture and finder-linker tests. 
  However, the error bit lights up in default flash RAM designs. 
   
 
SL2/4 #012: passed (now in B0XFT00 slot 15) 
 
SL2/4 #014: passed (now in B0XFT00 slot 16)

SL2/4 #027: passed (in B0COT20) 
 
SL2/4 #023: passed input capture but failed finder-linker test. 
  Low level problem, may be fixable (in B0COT20) 
 
 
============================================================= 
 
Location of hot spare boards (with green sticker on the front face): 
   - Three SL1/3 in stereo crate 
   - Two SL2/4 in stereo crate 
   - One SL2/4 in second floor B0 cabinet 
   - Two SL1/3 in second floor B0 cabinet. 
   - One SL2/4 in B0COT20 
 
The boards that were previously installed in the system have the 
words "in system before" written on the green sticker.  They 
should be used first.  All spares are loaded with input driver 
design.  I will reprogram the flash RAM to default designs at 
somepoint.  </pre>

<pre>Email to Bob Wagner 
 
        The CO, Bob Handler, noted a xft track segment hot spot in SL6 
cell 377 and neighbours (phi=354 degrees).  I also see many phantom xft 
hits for the corresponding TDC/XTC in b0cot00 slot 8, where phantom means 
that the XFT hit bit is set but there is no COT hit in the COTD bank. 
 
I then looked at YMON: the COT occupancy in SL6 cell 377 appears a factor 
of ten low (1% occupancy instead of normal 10% occupancy).  Do you know of 
anything wrong in this cell?

<pre>Email from Dave Ambrose 
 
On April 18th, I couldn't see anything unusual with this cell, in fact the 
plots look perfect, no noise or funny times/widths.  However, it could be 
that the repeater became partially unplugged during the endplug closing, 
or something like that.  This would create a combination of dead/hot 
channels throughout the cell.  I'll do a second set of runs between stores 
soon and find out.

<pre>Email from Bob Wagner 
 
    I took a closer look at YMon.  SL6-377 ch 0 looks normal (occupancy, 
multiplicity, width, average time), but the other 11 channels are completely 
dead.  Neighboring cells look fine.  As Dave said, this is probably a badly 
plugged cable at the repeater, since no one has accessed the TDCs since he 
took his run before the baggie was installed.  The remaining possibility is 
a badly plugged HV ribbon, but we did not even remove the Faraday cage over 
this region.  Dave's upcoming pulsing run should eliminate the HV ribbon 
possibility.

<pre>See Shift elog for this day. 
 
        I think the hot spot in the XFLD Linker occupancy plot (board #5 
chips 6 and 7 at phi=355 degrees have occupancy 50% above normal) is from 
the hot spot of axial SL3 track segments.  When the COT group has an 
access to fix a suspected stuck repeater cable in COT SL6 cell 377, it 
should go away. 
 
Triggers that use 4-layer tracks are not affected. 
 
Any triggers that use 3-layer tracks will be affected, with 50% more 
tracks than normal for a 2.5 degree range around phi=355 degrees, for runs 
after #143588, (Sat Apr 21 although COT was not on at full gain until 
evening of Monday April 23).

<pre>TrigMon plots
-------------

The XFLD Linker plot shows both 3-layer and 4-layer XFT tracks and has the
hot spot. The bottom plot on the XFT Finder and Linker Canvas shows only
4-layer XFT tracks and does not have a hot spot. Therefore it is only in
the 3-layer tracks.  (Note Cheng-Ju Lin is currently improving the plots)

Will try to power cycle the offending crates to see if that 
solve the problem.</pre>

<!-- Comment: Sun May 26 18;58;04 comment by...Cheng-Ju -->
<pre>Power cycle did not solve the problem.  The green done
LED was not on for finderboards B0XFT00 slot 4, 7, and 13.
Re-programming the flash RAMS for slot 4 restored the
done LED light.  To be safe, I re-programmed the flash
RAMs for all the finderboards.  Now the finderboards
go through COLD-START okay.

The linkboard problem seems to be associated with the
CDF clock.  After the CDF clock was restored, the linker
boards went through cold-start okay.

<pre>Peter Wilson power downed b0xft00 this afternoon to update  
the VME PROM for the TRACER (see e-log entry "Thu May 30 
16:00:39").  After the crate was powered up and rebooted, 
finderboard in slot 15 failed cold-start in Run_Control. 
The errorlogger message indicate that flash RAM download to 
FPGA failed for slot 15. 
I visually inspected the front panel and noticed that the 
green done light was off.  After the crate was power 
cycled, the done light was still off.  I re-programmed the 
flash RAM for all the chips for slot 15.  Everything was 
okay except the pixel chip download failed.  Second attempt 
at re-programming the pixel chip flash RAM also failed. 
Finally I reseated the board and that miraculously solved 
the problem.

<pre>The questionable XTC is b0cot17 slot6a (not 18a).</pre>


<!-- Date: Fri Jun 7 18:40:02 2002 -->
<pre>At first, the stuck bit problem mentioned in the previous entry 
seems to be an XTC problem.  However, I tested the questionable 
TDC336/XTC154 in b0cot17 slot 6 in the clean room and it passed 
the capture and sensitivity tests.  I went ahead and put in 
a new XTC82 and tested it in the clean room.  The new  
combination passed the test in the clean but again failed 
the input capture test in the collision hall. 
 
I then swapped the finderboards in b0xft04 slot 19 and 20 and 
repeated the capture test.  This time, the stuck bit followed 
the finderboard to slot 20.  I swapped in a spare (this one used 
to be in the system until the recent spare board checkout) from 
the stereo crate.  Well, the stuck bit is confirmed to be  
from the finderboard chip 2C.  This is the first finderboard 
casualty since I've been here :-(</pre>

could be a chip problem?

<pre>TDC in b0cot00 slot 7 and b0cot11 slot 19 are having problem 
going through cold-start (see shift e-log entry  Fri Jun 14 
13:31:34 ).   
I matched two TDCs with XTC cards for Mike to be installed  
in the collision hall during the next access.  They are: 
    1.) TDC#295 / XTC#175  (100K EVENT TEST OKAY) 
    2.) TDC#178 / XTC#154  (100K EVENT TEST OKAY) 
 
  </pre>
<!-- Author: Cheng-Ju -->
<!-- Comment: Mon Jun 17 11;46;37 comment by...Cheng-Ju -->
<pre>Okay, Mike Kirby misread his notes.  It turns out that
TDC#295 is going to a stereo layer and that the other
TDC didn't need to be replaced.  So he returned XTC#175
and TDC178/XTC#154 remains in the clean room as spare.</pre>

 We got some beam time last night to take the XFT 
 test run data. The luminosity was not great (~3E30) 
 so I took slightly longer runs. The runs were taken  
 without the silicon.  
   
   - Run 147507 (~40min):  
      Default physics table (default prescales).  
      1-miss design for all four axial layers.

      changed from 10K to 40.  
      1-miss design for all four layers.  
   
   - Run 147509 (~40min):  
      Default physics table (default prescales).  
      1-miss design for inner two layers and 2-miss design for  
      outer two layers.  
   
   - Run 147510 (~20min):  
      Default physics table (L2 bit 48 prescale changed from 10K to 40).  
      1-miss design for inner two layers and 2-miss design for  
      outer two layers.  
   
   - Run 147511 (~40min):  
      Default physics table (default prescales).  
      2-miss design for all four layers.  
   
   - Run 147512 (~25min):  
      Default physics table (L2 bit 48 prescale changed from 10K to 40).

Hi Greg, 
 
I've looked at the XFT log.  The errors all came from one event: run 148157 
event 152516.   For that event, the SL1 chip in all the finderboards (three crates) 
reported segment finding error between data and simulation.  I've looked in the 
shift e-log and the only unusual event was a spike in beam loss during the 
run.  I don't know if that is related to the XFT anomaly. 
 
I'll look into this issue a little bit more to see if I can find an explantion. 
However, it appears that this is a one-time event (actually as far as I know, 
this is the first time this type of error has occurred).  All the subsequent 
(and earlier) XFT trigmon plots look fine. 
 
I'll deposit the new version of XFT trigmon code in CVS today.  The new 
version will print out a bright red warning message on the plots telling 
the CO to page XFT if the errors exceed a certain threshold. 
 
 
cheers, 
 
Cheng-Ju

&gt; Hi XFT guys, 
&gt; 
&gt;    There seem  to be a lot of errors in 
&gt; the SL1 plot for run 148157.  There was 
&gt; no note in the logbook from CO or anyone 
&gt; else.  Can you have a look and report? 
&gt; 
&gt; Thanks,

<pre>After Phil powered b0xft02 back up, finderboard in slot 17
failed cold-start.  The green done light on the front panel
of the finderboard remained off, suggesting a possible problem
with the FlashRAM design.  Reprogrammed the FlashRAM brought
it back to life.</pre>
