不收敛绝大多数情况都是电路参数设置不合理，这仿真不是让你去尝试的，是要计算设计完，验证的

看软件的计算算法，有的不会
只会出现一些莫名奇妙的值
牛蜗的膀翅了没
那个无非是降低求解精度
其实saber就可以
pspice也不错
每个软件都有自己的优缺点，没有最好的只有最合适的
多用用mathcad，比仿真更能促进提高

Automatic algorithm selection exhausted
*** ERROR "ALG_SINGULAR_JACOBIAN" *** Singular Jacobian matrix.
Some possible causes for a singular Jacobian matrix:
- Model operating outside of its intended region of operation.
- Node/subsystem with no connection to the reference (floating).
- Current loops (voltage sources/inductors in parallel).
- Missing equation and/or missing variable reference.
Potential problem variables/equations:
/n_83
Partial results were written to the initial point "dcerr".
execution time= 0.0156 sec.
