May I know how was the VCD generated in first place ?
In order to open a waveform using VCD, you need to convert VCD to WLF first.
Refer to KDB
Thanks for sharing the VCD file.
Looking at your .vcd file
line 14 $var real 1 aaaal VIO $end It seems like bit width is set to 1.
$var type bitwidth id name
Try to increase the bit width to fix the issue.
thanks for your reply ...
Unfortunately the SystemC VCD writer is writing the file in this way. Older Version of Modelsim did not have this Problem.
I found a solution for may Problem.
1 aaaal test $end
When I delete the width defintion of the real variable it works fine. Question is why ?
