[QuestaSim] WLF (dataset) files compatibility

Hi All, 

 

I have a WLF file, which was created with Questa v10.6, but I have Questa v10.4.  

 

So, it seems there is some incompatibility in the WLF versions, which are generated by the tool - please see the error message below:  

 

# WLF Error: Cannot open WLF file because of version incompatibility.# The WLF file version is 170. Modelsim 10.4c can read up to and including WLF file version 150.# Cannot open file: D:/LPHUD/units/bit/verification/bit_20180320_1319.wlf 

 

So, is it possible to save the WLF file in the Questa v10.6, so that it will be possible to open it in Questa v10.4? 

 

Thank you!

You can not.

If I'll convert WLF to VCD, will it solve the problem?  

 

Can Questa work with VCD files? How can I load waves to Questa from VCD? 

 

What's the best solution to walk around the problem?

Lookup vcd2wlf in the command reference.
