How to change .tran options in Virtuoso

Hi everybody

Virtuoso cannot find a DC solution for my extracted (Calibre) circuit. The message says that I46_node0, where I46 refers to my main circuit symbol in the testbench circuit, has no path to ground. However the same circuit has no problem when I use the "Schematic" instead of "Calibre". My circuit I46 has no net0 in it! Hence I cannot understand which node is responsible for this problem!

I thought that I may need to change "gmin" in order to help transient analysis. However, I could not find where I have to change it!

Can anybody help me with it? How to change gmin and how to find a referred net in a circuit which from a symbol view.

Regards,

Hamid

You didn't say which simulator you're using. Or version.
If it's spectre, gmin is found under the Simulation->Options->Analog form.
