在仿真中会遇到这个问题,大概是DC不确定还是啥的,不是很明白。
倒也影响仿真,网上搜了一下说是内存不足?
但是这个问题会造成仿真停滞挺长时间的,请问有谁解决过?是要仿真中加个什么option吗?

Finding DC approximate solution failed. Try again with try_fast_op set to no.
Notice from spectre during DC analysis, during SP analysis `sp'.
GminDC = 1 pS is large enough to noticeably affect the DC solution.
dV(I13.I0_DD_5:int_a) = 56.8909 mV
Use the `gmin_check' option to eliminate or expand this report.
