Concurrent version is being tested at Xilinx now.
Sequentially 50sec – Concurrent 40sec – Not fully optimized yet. – Focus has been on getting working.
Anticipate release on May 15th

Demo Board

Shipped originally without Cypress part
Cypress part now available
20 sent out
approximately 8 available
Discussion: Who should get remainder? Can second board be obtained?
Xilinx wiring problem – Neil email – Jumper block
Cypress Xilinx and Latice – Action item to provide ISC and SVF for verification. Send to Dave Bonnett to posted on IEEE working group website.
Send to Jason Baumbach at Cypress instead of Jack.

Thanks to Altera for preparing the demo board and to Xilinx for preparing the demo software.

Discussion: New Issues

Blank UserCode – No Change
BSDL ISC TCK Frequency – No Change
Entity List in Data File
Indicates: That the Data file can be used with a specified list of entities( really, device packages) Reason: Assist in design re-targeting and Technology migration but datafile remains the same

Motion: To allow multiple entity names in the datafile ( comma saparated list )
Made: Mark Moyer
Seconded: Dave Bonnet
Vote: 7-0-0

Discussion: Wim Driessen Issues
Existing items:

Add decision repeat capability – No change – We value determinism. Could be done under the proprietary flag. Fixed beat rate? Alcatel prefers to do adaptive on erase. Altera specs theoretical maximum erasure time. Cisco would move parts to another line if the erase times are slower. This is complicated. Would delay the standard. There are other scenarios for dealing with this. Does this go beyond erase. This is not a show stopper. The hardware part of the spec demands deterministic.

Consensus: Table for later date.

Break: 11AM

Discussion: Latest Spec Change Review

P94 Keyword list
P95 ISC fixed system pins
P100 ISC_Flow specification
P101-103 Assorted rules
P103-106 ISC_Flow description
P106-108 Data Input & Output Formatting
P108-111 Data Output Source Mapping and CRC Enable
P119 proc_preload

Recommendation -

Always synchronize at enable and disable even when dealing with devices sequentially or when devices have proprietary tag associatd with their actions.
All devices should be reach enable together and reach disable together.

Ken captured update edits from the discussion.

Discussion: Continue Wim’s issues Unprocessed Flag: How do you know what to do? What application do you call?
