BINARY FORMAT PROPOSAL
Bob Ross conducted the meeting and showed a revised Draft 6 version
with some introductory material changes as uploaded under
http://www.eda.org/ibis/adhoc/interconnect/index-bydate.htm
Bob had added more detail about not supporting or retaining comment
information after [Network Data]
John Angulo did a hex conversion of the example data by capturing a
memory dump from Microsoft Visual Studio. The format was set up as
little endian, so he would want to have the example changed to
[Binary] DFL. It would require editing to convert to DFB. John
will send the data to Bob.
Radek Biernacki suggested that the Draft should focus more on format
and leave the binary conversion discusion elsewhere. The interface
details depend on the utility. He sees no issues with supporting
binary converisons, but is concerned abouy possible resolution losses.
Radek also provided some comments based on feedback from other people
who looked at Draft 5.
Since the number of bytes is known in the binary format for all setups,
[Noise Data] and [End] can still be supported. [Binary] could also be
positioned under the [Noise Data] keyword. Bob indicated that removing
the restrictions concerning {Noise Data] and [End] is easy, but we will
wait for more discussion.
Another comment addressed the [Binary] syntax. It is too cryptic and
seems to follow the option line simplicity. With IBIS keyword methodology,
arguments can be more descriptive than the compact 3-letter sequence
(e.g., DFB). For example, a move descriptive format might be
[Binary] 64_bit 32_bit Big_endian
or something similar.
Radek will provide more details of the comments.
NEXT MEETING
The May 12 meeting is cancelled due to travel. The Binary Format
Proposal discussion will continue on May 19, 2010.
