["Swiezawski, Martin" <mswiezawski@xxxxxx>]

Aaron, 
I have been following the discussion between you and Daniel. TI is
currently using custom XML format that meets our debuggers' needs. We
have a combination of XSLT & scripts that perform initial translation
from either SPIRIT or some other format into debugger's XML format.
However, resulting files need to be tweaked a bit. There was couple of
reasons that caused us to move in this direction. A) HW specifications
did not contains CPU native registers B) non-standard names to identify
CPUs were used. Second issue is not that critical for single CPU
devices, however it is important for multi-processor devices, where you
need to know whether peripheral X is accessible and visible through CPU
1 or 2. 

We have organized our debugger XML database to have generic peripheral
files that are then included by device specific files. We are also using
a slightly modified version of an XML parser that allows us to handle
couple of tags in a special way. E.g. specify in device file included
peripherals' base address. Our backend debugger(C++) currently does the
parsing and provides register information to clients. 

In my mind, ideal solution would be to use SPIRIT. There would be a
standardized component that reads that data and provides it through an
API. Folks could then decide where this component needs to be plugged
into. However, a big hurdle that I see is standardized naming
conventions to be able to identify cpus, peripherals, registers and
match this with whatever the debugger is expecting.

Doug,

I have posed a bunch of questions recently that perhaps are buried in
the discussion, but I think that the most pressing one to answer is
perhaps where people see this info being used.  The reason that I think
this is important to answer now is that it will impact what is useful to
have as far as tooling goes.  In effect, the questions is whether or not
it is profitable for us to write java XML parsing code specific to
SPIRIT or not.  I know that you guys (Wind) have a debugger architecture
similar to ours in that you have a native debugger back end that your
Eclipse front end communicates with.  If you need the info in your
back-end, then either you need to parse it in the back end as well as
the front end, or you need to parse it in the front end and push it
through to the back. (make sense?)

I do think that regardless of the outcome of the discussion above, we
need to start identifying the extensions that are needed in the SPIRIT
schema and creating tools that use them.  I think that SPIRIT is the
only real hope of getting info from the semiconductor vendors in a
format that is useful.  What we then do with that info (use it directly
or translate it to another format that we use directly) is another
discussion.
