Hi Walter,

  A .dll being loaded such as this TX.dll does not know itself is 1st or 2nd
instance. It also does not know it's EDA tool or other library which is loading
it.

  However, it's RX which loads this particular TX.dll in this case. So if there
is a need, a proprietary API function like setInstanceID(int id) can be defined
for TX.

  Then after RX load this TX, it can call tx->setInstanceID(2) etc.  then TX
will
know its own role in the training process.

  Thanks.

Wei-hsing,

On Slide 12:

*       Start training:

*       Iteration between TX and RX either

*       Developer decides this should happen in RX's AMI_Initor AMI_GetWave

*       TX can train RX or vice versa right here

*       They are "dancing" together, only themselves need know who is leading.

*       It's the 2nd instance TX which RX is training or being trained.

How does the 2nd instance TX AMI_Init know that it is the second instance?

Hi,

  Earlier this week at the ATM WG meeting, I proposed an alternative
back-channel
flow and was given an AR to document it for review or further discussion.

  You may find it in the slides linked below:

   <http://www.spisim.com/support/ticket/IBISATM/SPISim_BackChanFlow_Proxy.pdf>
http://www.spisim.com/support/ticket/IBISATM/SPISim_BackChanFlow_Proxy.pdf

  I intended to keep it updated (at this link) based on your comments until it's
been reviewed or even later.

  Meanwhile, I have also written a blog post recently regarding digital signing
AMI model etc. (another topic of discussion at the ATM WG earlier this year).

If interested, you may find it at the linked below:
