Sorry for last-minute questions on BIRD158, but I wanted to ensure these could
be addressed during the technical discussion in the Open Forum:
1) The TX and RX "Analog Termination Circuit" sections - it's not
immediately clear where in the specification these are supposed to go. It
would help to note the section in which these are to be inserted.
2) In the text, the following phrase is used:
"Note that when the reserved parameter Ts4file is defined in the AMI model the
Tx or the Rx schematic shown above is to be used in lieu of the analog buffer
model and the package defined in the .ibs file. "
Will the phrase "and the package" regarding package models be revised or
removed once BIRD189.x is approved?
3) Related to this, the entire sentence should appear *before* the link
setup circuit diagram that immediately precedes it, to prevent reader confusion.
4) Also related to this, the link setup diagram should be altered to make
the package portion of the "User Setup" block optional. Otherwise, the diagram
conflicts with the statement regarding the replacement of the package
information in the .ibs file.
5) The last paragraph of the BIRD text to be added to IBIS mentions step
responses vs. impulse responses. As the phrase "step response" is never used
in IBIS 6.1, and the information supplied applies just as much to impulse
responses, is the entirety of this paragraph needed?
Thank you!
