You can't have any negative values in your VCD file. If for example, -1000 is your minimum time value, then put that in the $timezero directive and the rest of the values start at zero and go up monotonically. That is, you dump (actual value - $timezero_value) See if that works for you. -Tony -----------------------------------------From: "Rida Shamasneh" To: gtk...@li...

I tried to create such a VCD file with "$timezero -1000 $end" but tool gets stuck. Is the attached VCD file valid?

You can try adding something like this before you initially dump scopes to see if you can achieve the results you want $timezero -1000 $end ...in that case, -1000 would be the initial negative value which would map to a timestamp of #0 as this will offset all the time stamps by the specified value. I don't know if this will cause issues in the tool using negative values as I have never tested that. -Tony -----------------------------------------From: "Rida Shamasneh" To: gtk...@li...
