Colin, That's a nIcely designed web site. Do the contest terms really need to be as follows? ----- Assignment of Ownership of Submission. By sending a submission, you assign and agree to assign to Agilent your entire interest in the submission and in all intellectual property rights in or disclosed in the submission (including copyrights and patents, and you agree to execute all documents and cooperate with Agilent in all necessary activities to obtain or enforce intellectual property rights at Agilent’s expense. Agilent, in its sole discretion, is free to use, copy, modify, display, distribute, perform, or import the submission as it sees fit without obtaining your consent or incurring any obligation to pay you anything. ---- SiSoft is not able to submit an official entry under the current terms. I can report that we were able to take the S-parameter data and optimize a 4 tap FFE/peaking filter/DFE solution that provided 423mV and 130ps of eye opening at a data rate of 6.25 Gbps (viewable at http:/www.sisoft.com/images/contest_eye.jpg). As we can't submit an official solution under the current contest terms, those interested in these results should contact SiSoft directly. Todd.
