Hi Folks-

Meenakshi and I discussed the file format for running test vectors
through the DFEA using the DSAT.  Here is what we came up with.
First, some definitions:

"Event" = one 132ns period (seven 53MHz RF clock cycles) during which
  data is sent to the DFEA or received from it.

"Turn" = one test cycle for the DFEA, wherein a number of Events
  are sent to it and the received data captured.

A "Turn" may contain up to 73 events (512 word Xilinx block RAM size,
with 7 locations used per event).

File format details:

- Comments begin with #.  Anything from the # to the end of the line is
  ignored.

- Numbers may be decimal or hex.  Decimal numbers must contain only
  digits 0-9.  Hex numbers must either begin with "0x" or contain at
  least one character a-f.

- whitespace (tabs, spaces, blank lines) permitted anywhere
  except inside words or numbers

File structure:

<header>
<turn>
  <event>
  <event>
   ...
<turn>
  <event>
  <event>
   ...

Where the elements are as follows

  <header> = an arbitrary string containing at least the name and version
	     of the software creating the file

  <turn> = a group of events, with the start of the turn
	   marked by a line beginning with "TURN".

#------------------------------------------------------------

  <event> = a header line followed by 57 numbers (for data output to DFEA)

    EVENT          # start of event marker, must start with "EVENT"
    <scl_data>     # SCL bits for this event as follows:
		   #   bit 0 - FX (first crossing)
		   #   bit 1 - SG (sync gap)
		   #   bit 2 - L1A (level 1 accept)
		   #   bit 3 - SCL init

    <lvds_0_word_0>    # first link first word (28 bits)
    <lvds_0_word_1>    # first link second word
    <lvds_0_word_2>
    <lvds_0_word_3>
    <lvds_0_word_4>
    <lvds_0_word_5>
    <lvds_0_word_6>    # first link last word

    <lvds_1_word_0>    # second link first word
    <lvds_1_word_1>
    <lvds_1_word_2>
    <lvds_1_word_3>

       ....

    <lvds_7_word_6>    # eighth link last word


#------------------------------------------------------------

   <event> = a header line followed by 43 numbers (for data captured
             from DFEA)

    EVENT          # start of event marker, must start with "EVENT"
    <status>	   # arbitrary status word, details tbd

    <lvds_0_word_0>    # first link first word (28 bits)
    <lvds_0_word_1>    # first link second word
    <lvds_0_word_2>
    <lvds_0_word_3>
    <lvds_0_word_4>
    <lvds_0_word_5>
    <lvds_0_word_6>    # first link last word

    <lvds_1_word_0>    # second link first word
    <lvds_1_word_1>
    <lvds_1_word_2>
    <lvds_1_word_3>

       ....

    <lvds_3_word_6>    # 4th LVDS link last word

    <sldb_0_word_0>    # first SLDB link first word

      .....

    <sldb_1_word_6>    # second SLDB link last word



Please feel free to comment.  If we agree on this I'll post a slightly
more formal description to the web.
