gmin: Spectre adds a conductance value "gmin" between non-linear devices
iabs: maximum acceptable error in absolute current
vabs: maximum acceptable error in absolute voltage
Hi can anyone tell how to remove the gmin problem from cadence? actually in log it is displaying that Gmin=1 pS is large enough to noticeably affect the dc solution.

gmin is not a problem, it is trying to be a solution.
The more likely problem is unrealism in models. What FET has
a real leakage under 1pA/V? Right.
If your circuit is sensitive to the gmin mesh's effects, you
are either attempting something really spectacular (and
likely unrealizable) or you will be surprised later when you
get the real device and the real transistors leak like real
transistors do.
