Hello,

Does exist a document with examples on how to create  "VCD Info File" for a given "VCD File"?

Thanks

    Well, after correcting cal_dac name I see that there is no proble (except mapping one wire form vcd bus, i.e. grp1_adc[50:0] to a signal in schematic) there is no problem, it's Ok.

    All other "no connect" warnings concern schematic internal nodes (I saw it after after activating an optinon allowing to display all warnings).

    Nevertheless the signals at VCD-schematic interface do not evolve as they should, i.e. I don't see clock

    You can upload other files via Insert Image/Video/File. You might need to give the file a ".txt" suffix though.

    Perhaps with an example I can look and see what you mean by this:

    Here it is:

    I mean I see clock (i.e.grp1_clk)  in SimVision, but don't see it in Virtuoso Graph window once simulation terminated.

    Resolved.

    In SimVision I've exported range 700us ... 1100us hoping that time will be shifted to 0 ... 400us, that wasn't the case.
