Vih, Vil, Vmeas etc..

     Hi all,
     
     I wonder if someone already made the same comment ;
     
     The [Model] statement only allows 1 value for Vih, Vil, Vmeas, Cref,
     Vref, Rref. Whereas the PCI or AGP, for example, specify Vih,Vil &
     Vmeas as a ratio of the power supply. Also, the test conditions can be
     different between rising and falling edges (exple : Cref=10pF for all
     AGP max timings and 0pF for min timings).
     
     I think ibis spec should include typ/min/max statement for all these
     values plus a 2 test load conditions for rising and falling edges.
     
     Is this going to be included into 3.0 or 3.1 ?
     
     note : as of today, the only patch I found is to cope with several
     ibis files ! not very easy.
     
     thanks,
     
     Jean-Christophe PAUTRAT,
     HEWLETT-PACKARD.
