回复 11# 桃儿爷。
好久没有看论坛了,我来回答下。 该警告提醒有些晶体管的引脚没有连接。而为了求解的方便性,将那个端口连接上一个极大的电阻,这样做的好处是方便建立整个电路的求解矩阵。仅此而已。实际上如果你自己的晶体管电路如果都连接正确,基本不用管这个警告。
ADS官方解释如下:
In the case of a circuit with a wire that is missing, a message such as the following can appear in the Simulation/Synthesis Messages window during a simulation:
Warning detected by HPEESOFSIM during DC analysis "DC1".
Circuit as given has no unique solution.
A virtual resistance of 1 TOhms was added to each node. In the case of unconnected wires or pins, choose
Tools
>
Check Representation, then select
Open connections
and click
OK. All unconnected wires and components are highlighted, making them easily visible on the screen. Connect these to the correct circuit node. |
