No opens were raised. 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.
