If I am not mistaken, Modelsim has this feature and it is very useful, I even consider it somewhat of a core feature. Is this not the case for others? Has anyone else thought that this might be useful in ISim? Is there some way that I can request the addition of this feature in some future version of ISim? I am not trying to put down ISim. I just haven't gotten any feedback on this issue and I was wondering what other people thought. Is this something that other people use in Modelsim? Thanks.
