Hi,everybody. I always do some simulations before designing PCB.But one quesiont often occurs. Such as in the same circuit,if the value of a resistor is changed,there maybe a message:
COMFIRM Errors occured during simulation,Do you want to view the errors now?
If I pressed the "YES" button,there will be some more messages below: Note:Starting Gmin Stepping Note:One Successful Gmin Step Note:One Successful Gmin Step Note:One Successful Gmin Step Note:One Successful Gmin Step Warning:Gmin Step failed. Warning:Gmin Stepping failed.

Did someone encounter such problems?What reason??
Thanks all.
