Fangy, As far as I know, the Use_Init_Output value depends on what the model's content is, in other words it is to tell the EDA tool how to handle the model, and not the other way around...

For example, does the standard intend to let model implement two behaviors for Use_Init_Output=true and false, and allow EDA tools to get different output from AMI_Init by passing Use_Init_Output=true or Use_Init_Output=false in the argument? Does a model have to support both scenarios? I think the standard is not clear about whether the parameters are used by models to instruct EDA tools how to call the model, or used by EDA tools to instruct the models how to function. Thanks, Fangyi
