Hi guys,
Can you help me to deal with this simulation error, I use Hspice to simulate. all the warning and error are following:
**warning** effective csat(is) = 100.0000m is too large in diode 0:d2
**warning** effective csat(is) = 100.0000m is too large in diode 0:d3
**warning** rs for 1:d3 limited to 1.000E-05
**warning** mosfet device 1:m1 cdsat is too small at temperature 25.000 value= 1.00000E-32,cdsat reset to epsmin
**warning** mosfet device 1:m1 cssat is too small at temperature 25.000 value= 1.00000E-32,cssat reset to epsmin
**warning** conductance of 0. on node 1:5 iter= 12
**diagnostic** rebuilding matrix with pivot option
**diagnostic** rebuilding matrix without pivot option
**diagnostic** dc convergence failure, resetting dcon option to 1 and retrying
**diagnostic** dc convergence failure, resetting dcon option to 2 and retrying.
no convergence with standard algorithm, trying damped pseudo-transient
*** initial damped pseudo transient completed. *** *** final try started ***
**warning** This was a difficult operating point. You can speed up your simulation by specifying: .OPTION CONVERGE=1 **error** internal timestep too small in transient analysis
time = 5.36237E-09; delta = 1.90735E-15; numnit = 335
Best Regards Jay
