Jean Thevonet Posted February 6, 2018 Report Share Posted February 6, 2018 Dear users, I'd like to compare the vcd output of differnt versions of our prototype. Is there some kind of vcd diff available ? Graphically ? Regards, Jean Quote Link to comment Share on other sites More sharing options...
maehne Posted February 6, 2018 Report Share Posted February 6, 2018 This kind of functionality needs to be implemented by your VCD trace file viewer. E.g., the impulse plug-in for Eclipse available from toem.de seems to offer this kind of functionality in its "analyze" variant. Quote Link to comment Share on other sites More sharing options...
Hans64 Posted February 6, 2018 Report Share Posted February 6, 2018 Modelsim (and most likely all other commercial simulation) provide a conversion utility to convert VCD to their own format. For Modelsim this is vcd2wlf, convert both files to the wlf format then use Modelsim's filecompare to do the comparison (with all the available bells and whistles which you may need). You can quite easily script this up and add it to a GUI button. Good luck, Hans.www.ht-lab.com Quote Link to comment Share on other sites More sharing options...
Jean Thevonet Posted February 7, 2018 Author Report Share Posted February 7, 2018 Thanks, I tried with impulse and from first impressions -- it seem to be easy and comfortable. You just have to select the 2 files and get to impulse->Compare with each other . A dialog gives you some options (what and how to compare). BUT - For this extended functionality I had to request the analyze license key (free for non-profitable or 90 day stuff). :-( Will tomorrow check with analog and tlm data.

Jean Thevonet Posted February 21, 2018 Author Report Share Posted February 21, 2018 I found this : http://toem.de/index.php/projects/impulse/manual/167-15-comparing-signals-and-records The comparisson seem to be independed of the data type (analog, digital, ...).

Bruno Godrabeli Posted March 14, 2018 Report Share Posted March 14, 2018 Hi all, i tried comparing but i can not access the menu option. Any idea ? # Bruno Quote Link to comment Share on other sites More sharing options...
maehne Posted March 14, 2018 Report Share Posted March 14, 2018 I guess you tried comparing traces in "impulse". In that case, you need to make sure that you have obtained the correct license. You need to unlock the "analyze" variant of impulse. Quote Link to comment Share on other sites More sharing options...
