Hi,

I am doing bias point simulation and getting fatal error **“Pseudo transient analysis failed to find the operating point.”**.

Sim log -

*MOSFET M1•XM3•XU1•XU1•X1 has L=1e-06 which is smaller than can is be realistically modeled with a level 1 equations.*

*MOSFET M1•XM2•XU1•XU1•X1 has L=1e-06 which is smaller than can is be realistically modeled with a level 1 equations.*

*MOSFET M1•XT2•XU1•XU1•X1 has L=1e-06 which is smaller than can is be realistically modeled with a level 1 equations.*

*Ignoring shorted diode: “D1•XD12•XU1•X1”*

*Ignoring shorted resistor: “REN•XU1•X1”*

Any help is really appreciated.

Thanks,
