我不懂 不过只是提议
切换到cond2层之后画一个行么
在底层画铜层呢
好像protel中可以这么做啊

网友回复:

地参考面没设置好，所以仿真出来的结果不对。

这个倒不难，主要就是两个端口参考地的设置。
Defining a Ground Reference    Ground references enable you to add explicit ground references to a circuit, which may be necessary if no implicit grounds exist in your design.
Implicit ground is the potential at infinity, and it is made available to the circuit through the closest infinite metal layer of the substrate. Implicit grounds are used with internal ports and with single ports that are connected to objects on strip metallization layers.
There are instances where the distance between a port and its implicit ground is too large electrically, or there are no infinite metal layers defined in the substrate. In these cases, you need to add explicit ground references to ensure accurate simulation results. For more information on using ground references, refer to "Simulating with Internal Ports and Ground References".
You can apply ground references to the surfaces of object. The object must be on strip metallization layers.
Note Multiple ground reference ports can be associated with the same port. To be associated with a single port, the ground reference port should be a port attached to an edge of an object in the same reference plane as the single port.
To add a ground reference:
1.
Choose Momentum > Port Editor.
2.
Select the port that you want to assign as the ground reference.
3.
In the Port Editor dialog box, under Port Type, select Ground Reference.
4.
Under Associate with port number, enter the number of the single or internal port that you want to associate with this ground reference. Make sure that the distance between the port and ground reference is electrically small.
5.
Click Apply.
