Dear colleagues: The recent dialogue concerning PCI-X is an excellent example of incomplete or misleading specifications being used as design manuals. The point of this, as we SI professionals all know, is that SI technology and timing based issues are not a matter of legislation or fiat. The data is often based on a limited number of simulation cases completed by an unknown standards committee member. Modern SI and timing standards require a thoughtful and complete analysis over a wide variety of cases, devices, conditions, etc. I would like to make a serious suggestion for modifying the SI and timing specification process. I believe that the creation of technology based portions of standards should be introduced and investigated on a preliminary basis in the manner now followed, but follow that up with an open invitation for SI professionals to go to the specification web site and allow the down loading of data to check the committee's work. Hopefully, the SI professionals will check the work with a wide variety of tools and new configurations. As various cases are investigated, the results of the work would be reported back to the specification web site. Dialogue on this suggestion is warmly requested.
