ModelSim 6.5b mismatch name & waveforms

I recently upgrade to Quartus II 9.1 and ModelSim 6.5b subscription editions.

After running a sim in ModelSim, the internal net names will not always match up with the waveform display in the "Wave" window.

After hitting F5 a few times and moving the vertical scroll bar, I can sometimes get them to line up again, but it's a pain.

I experienced the same problem in ModelSim 6.5b Starter Edition.

Anyone else having this problem? I did not experience this problem before the upgrade.

    I have the same problem. Only one of the 3 vertical panes of wave updates when you do somethink.

    Menu View refresh display works but it very annoing.

    Hi Pancake

    Yes finally I can, and better I can add a workaround for the problem, I found this morning.

    The problem never shows in my first simulation, but appears when I change a source file and rerun it.

    I do not define projects in modelsim.

    I just use the cd command to go to the proj dir.

    Then I use a run.do command file (executed with do run.do) The run.do could be like this

    # End present simulation

    quit -sim

    vcom myfile1.vhd

    vcom myfile2.vhd

    vsim -t 1ps work.tb_sram_x16

    do wave.do

    run 250 ns

    The wave.do file holds my stored wave setup.

    The workaround is to close the wave window between each run.

    This can be done by adding

    noview wave

    after

    quit -sim

    in the run.do file.
