Honored ContributorThanks Jake.
Just to put things in context - this is our very first DDR2 design, we want to ensure that the IP controller is working OK, that we'ce configured it properly, that the DDR2 is initialised Ok and mode registers loaded with correct data, we're not violating the protocol regarding timings between issuing commands, refreshes etc. I know for SI work I'll need to get the scope and active probes out but for the type of stuff described the analyser is a good tool. I don't want to blow our budget on an interposer which probes at the SODIMM fingers where SI is not great (Nexus don't guarentee that the analyser will be able to capture properly here) whereas the Nex-Vu product probes at the DRAMM balls wher e our simulations show acceptable SI. Our design will be populated with two different densities of SODIMM so ideally I want to verify both modules - one interposer would do the job but it would take two Nex-Vue boards (at many $) Stephen
