No DC convergence.
To search for a more robust convergence algorithm,
set ConvMode=1 on the DC analysis and perform the DC
simulation again.This will cause the simulator to vary
the convergence parameters and report which parameter
setting produces the fastest convergence.Status / Summary

当中提到要把ConvMode=1，可是我没有找到在哪里设置这个参数
这个问题比较棘手，望达人赐教
多谢
