I have the performance monitor up to check on that and I have plenty of memory. 16GB and I am using 6GB.

CPU usage is at about 20%

I get this message when I first load the project, before it runs.

I went back to the code (I am only using 16k LEs and a few multipliers, no special IP at all!) and I cut out everything I could get away with, recompiled and did NOT get the message.

Modelsim ran at an acceptable speed.

I then went back and did a restart and on the restart I got that message and Modelsim ran like a dog.

So I quit modelsim and simply restarted modelsim from scratch, reloaded the project: NO MESSAGE!

And it ran fine. Does it have something to do with restarts from within modelsim. I have noticed a lot of other bugs too. Is this just another bug??

Thanks for your help,

Don
