Modelsim problem

If you are under maintenance then try a later release (currently 6.1c), alternatively, log a support call with Mentor/Europractice,

I don't have the answer, but there are a couple of things to try.

(1) there may be problems in the interaction between HDS and Modelsim. So try invoking ModelSim standalone, loading the design, and "Add Wave" from its own GUI, and see if the problem persists.

(2) I vaguely remember at least one "bad Modelsim" around that era; it may be worth finding out the latest Modelsim you are licensed to run. If you are running it, then try a slightly earlier one...

My distributor was very good about helping to the extent they could on an expired ("out of maintenance") licence, it ensured I came back to them when the company had more money!

Hi Jaime,

Brian made a good point to run your design outside HDL designer. I had a similar problem some time ago and fixed it by un-ticking the "Enable Communication with HDS" tickbox which you find on the start Modelsim dialogue box. I would also suggest to update HDS to 2005.2 if you are not already running that version.

In my experience, this is almost always caused by *mumble* problems in compiling libraries. Okay, that might be somewhat vague, but I have not figured out exactly what circumstances cause it. One circumstance that causes it is if I move a library, but don't recompile a file (which may be in another library) that uses it.

Often, I can find the problem simply by reading the transcript file that Modelsim generates. Somewhere in there, I will usually find a mention of a library that it didn't load, or had a problem with. Another method is to simply recompile all the libraries and files you are using, in the correct order.

As a final desperation measure, instead of loading the whole project, load just pieces of it. Eventually you can narrow it down to the piece that is crashing, and work your way backwards to find exactly the file. If it is in a library, just go to the library directory and load pieces of that into Modelsim.

Thanks to all of you who replied. I played around a bit with the subject, and finally could solve it. I had some problems with the license environmental variable (WinXP Home). NOw runs flawlessly.
