As per my original text: Hi all, At the end of yesterday's meeting, I asked the EDA vendors in the group if they'd describe their GetWave() flows, for Tx modeling, to the group. I am confining my inquiry to Tx modeling only. -db From: ibis-interconn-bounce@xxxxxxxxxxxxx [mailto:ibis-interconn-bounce@xxxxxxxxxxxxx] On Behalf Of Muranyi, Arpad Sent: Thursday, January 10, 2013 1:04 PM To: 'ibis-macro@xxxxxxxxxxxxx'; 'ibis-interconn@xxxxxxxxxxxxx' Subject: [ibis-interconn] Re: A rephrasing of my previous question, re: your GetWave() approach. David, I would like to ask you to refine your question(s) with a little more detail. Please specify which Init and GetWave function you are referring to (tx or Rx). This way I am afraid that the responses you will get will be all over the horizon... Thanks, Arpad ========================================================= From: ibis-macro-bounce@xxxxxxxxxxxxx<mailto:ibis-macro-bounce@xxxxxxxxxxxxx> [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of David Banas Sent: Thursday, January 10, 2013 1:24 PM To: 'ibis-macro@xxxxxxxxxxxxx'; 'ibis-interconn@xxxxxxxxxxxxx' Subject: [ibis-macro] A rephrasing of my previous question, re: your GetWave() approach. Hi all, At the end of yesterday's meeting, I asked the EDA vendors in the group if they'd describe their GetWave() flows, for Tx modeling, to the group. This request drew quite a bit of reluctance, understandably. I would like to rephrase my question: In the case of Tx modeling only, what processing flexibility do you gain by not being required to accept the channel impulse response as input to the GetWave() function? My hope is that the above question is safer to answer and, yet, might still further our common understanding of the reasons for the different assumptions, regarding input signal and output location, made for Init() and GetWave(). If you'll recall, after our recent re-read of Sec. 10 of IBIS v5.1 (and if we agree to take Sec. 10 as a normative part of the standard, as opposed to just one example interpretation of it), those assumptions are: Flow Type Input Signal Presumed Physical Location of Output Init() Channel Impulse Response Input to Rx Eq. GetWave() Binary Data Stream Input to analog channel If I am merely the last person to understand the motivation for the different assumptions, above, I apologize for my obtuseness and thank you, in advance, for your indulgence.
