i try to design one rail to rail MOS op-amp
i use orcad for plot the circuit and then by R&H convert to hspice model my AC design have no out put and in .sp file of hspice i see
**diagnostic** dc convergence failure,
resetting dcon option to 1 and retrying
**diagnostic** dc convergence successful
you can increase the efficiency of the
operating point calculation by setting dcon= 1
in the .option statement
is my problem for this massage ?
