Hi Torsten, Can you send me the code at jim at synthworks dot com. I can take a look at it to see what I can.
I have a scoreboard that does all of the above. It works well in 10.3. You may wish to run your test in one of the 10.3 versions. The socoreboard model is a release candidate for OSVVM, so if you send me an email, I will send it to you.
