FYI, in an earlier mail, I asked whether PDFs could be used directly under IBIS-AMI. To clarify, the usage of PDF was as "probability distribution function." The reason for the question, plus some concerns about TX jitter treatment, are outlined in a paper by Bryan Casper, Ganesh Balamurugan et al, entitled "Future Microprocessor Interfaces: Analysis, Design and Optimization." It's available through IEEE and other sources. The full citation follows. IBIS-AMI support for this style of data input would be highly useful. - MM Casper, B.; Balamurugan, G.; Jaussi, J.E.; Kennedy, J.; Mansuri, M., "Future Microprocessor Interfaces: Analysis, Design and Optimization," Custom Integrated Circuits Conference, 2007.
