  • 仿真不收敛问题的讨论

    2007-04-21 22:43:36

    **error** number of iteration exceeds min(7000, 20*itl1)=  4000 in pseudo
    tran process (converge=1 process). Usually this happens when the
    models are discontinous, or there are uninitialized bi-stable cells
    (flip-flop) in the circuit. By setting options dcon=-1 and converge=-1
    you can disable auto convergence process. Retry the run, non-convergence
    diagnostics will provide useful information about the nodes and devices
    which can be used to work around the non-convergence problems.
    *** error ***: no convergence in dc sweep curves at  -40.000  

    上面说的setting options dcon=-1 and converge=-1,我不知如何设置?请指点迷津。。

    .option dcon=-1 converge=-1
    放在网表前面
    你的问题可能是初始floating点没设好?
