Opening Gowin VCD files in Questa sim

[ali_asadzadeh]

Hi,
Gowin logic analyzer would produce VCD files, I want to open them in Questa
After searching the web I found that  the command inside Questa is this

Code: [Select]

vcd2wlf  FFT.vcd fft.wlf
And this command would trough an error like this

VCD-Read error VCDR_PHASE_ERROR at line 256

Do you have any Idea what might be wrong?

Any Idea how to solve the VCDR_PHASE_ERROR?

I wonder if you tried the files on gtkwave. Just for curiosity. It seems that this vcd format exist in several flavors. Some synopsis tools emit also vcd files that seems a bit garbled on the eyes of gtkwave.
It is a text file after all, you could open it and have a look at the given line, and the lines around it to see which command seems to cause problems. Maybe it needs to be "reparsed" and fixed

gtkwave Can open it successfully,
Thanks But I need to be able to open it in Modelsim too.
