Arpad, Vladimir, There was great effort to define each of the parameters in strict mathematical terms. Please indicate specific parameters that the BIRD does not either define mathematically precisely, or indicate how the parameters are to be used in either the statistical or time domain simulations.

There was no response to it since I posted it. I think it would be good to get some discussion going on these questions/comments. Thanks, Arpad From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Muranyi, Arpad Sent: Friday, July 01, 2011 11:53 AM To: IBIS-ATM Subject: [ibis-macro] Comments on BIRD 123.2.2 from Mentor Walter and All, I am forwarding Vladimir's comments on BIRD 123.2.2 to this list for discussion. Please look at his comments which are in the attached Word document. Since Vladimir is also on this email list, please direct your answers, questions and comments to him. (I don't want to be the middle man in such conversations.). The general problem is ambiguity of given definitions when it comes to implementation in EDA tool. The Bird does not seem to be logically complete (does not cover all cases, such as Time domain and Statistical flow), or does not provide all necessary parameters affecting the results (such as either giving frequency content of Tx Gaussian jitter, or making it defined as white uncorrelated jitter, etc.) Thanks, Arpad ============================================================
