Hi SI-LIST, I am looking for design guidelines for the Intel QPI bus (Xeon E5), something about the equalization and de-skew capabilities available in the processor that will help me define the si constraints. Can one of you folks point me to some design documents or constraint sets that have worked for you? Or an example 4 processor and I/O hub design?
