报错信息如下:
Error found by spectre during IC analysis, during transient analysis `tran'.
ERROR (SPECTRE-11006): Matrix is singular (detected at `I0.M0:int_d' and `E1:p').
ERROR (SPECTRE-16080): No DC solution found (no convergence).
The values for those nodes that did not converge on the last Newton iteration are given below. The manner in which the convergence criteria were not satisfied is also given.
Failed test: | Value | > RelTol*Ref + AbsTol

若GND节点不接地,
最后结果不会报错,但是管子都不能正常工作。
为什么会这样?图1的报错该怎么解决?新人跟着教程做,老是出问题。感谢各位解答!
