Re: [10GMMF] Towards receiver test responses



It wasn't included in the spreadsheet, but to generate the 25 cases for each type of pulse response, I swept my target %tile from 88% to 99.5% in 0.5% increments, and included 99.8% to get close to 5dB as requested by Paul. The same %tile target was used for PIE-D and finite DFE, i.e. I did not "relax" the finite DFE targets when looking for symmetric and postcursor type responses. Of course, the %tiles are based on my modeling assumptions, which I've presented previously. If these assumptions change then the %tile interpretation will shift.

I may have missed it, but did you show here what are the %tiles on Gen67YY w/r to the DFE cases and PIE-D?

The attached .xls file contains the candidate TP3 ISI parameters that were requested during the TP3 telecon on 5-Apr-05. The PIE-D targets were generally swept from ~3.5dB to ~5dB, although there will be some variation in the resulting PIE-D due to the nature of the search algorithm.

The results for the split-symmetric response deserve some comment. The first 11 entries in the worksheet are essentially identical. This occurs because split-symmetric responses, as we have defined them, do not exist for PIE-D < ~ 4dB. For PIE-D targets < 4dB, the search algorithm finds the best response possible consistent with the constraints resulting in the same ISI parameters for these cases.
