probing nets in Virtuoso Schematic isn't recognized in Simvision

Hello,

Before running simulation I probe nets in Virtusoso Schematic (key 9), hoping that these net will be recognized by Simvision.

But after launching NC-verilog, compiling/netlisting and than launching Simvision I always see the following message in Simvision console

 ncsim: *E,PRNONE: No new objects to probe in scope test.

So I need once more select the nets in the Simvision Browser.

Where I've been mistaken ?

Thanks in advance.

Pavel.
