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?

S-Parameter Analysis `sp': freq = (GHz -> GHz)

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.
DC simulation time: CPU = 72.9089 s, elapsed = 72.9168 s.

你好，请问你这个问题解决了吗?我后仿运放的时候也碰到同样的问题，。
