Hi Kevin,

Out of curiousity, just what were you using for the design and the testbench when you say that you reproduced the problem?

Josy sent me the design files via email, and I performed a quick sanity check to see whether Modelsim-SE generated the same error.

Did you verify in the list window that X and Y are changing on the exact same simulation delta cycle?

Let me check ... (I'll fire up my machine with 10.0c on it and re-run the simulation) ...

Your talk of conversion functions and intermediate signals ...

I looked into that to see whether there was some weird promotion to full integer going on, there wasn't.

Cheers,

Dave
