Hi, The revised BIRD is posted in the archive section at http://www.vhdl.org/pub/ibis/macromodel_wip/ For those who are unaware, one of the major changes in the BIRD is the accommodation of a new parameter file that will contain all the reserved as well as the user defined parameters for an AMI model. The parameters will be declared in a tree syntax format. Please make comments, suggestions, so we can improve the document. Thanks, -Ambrish.
