大家好,我在布局上创建了一个功率分配器,当我在原理图中使用库中的组件并进行模拟时,我收到一条错误消息。
我不知道如何解决它。 有谁能够帮助我? 感谢回复。 Jefferson schematic_power divider.jpg89.7 KBsimulation_error.jpg83.1 KB 以上来自于谷歌翻译 以下为原文 Hi everyone, I’ve created a power divider on layout, when I use the component from the library on the schematic and do the simulation, I get an error message. I don't know how to solve it. Can anybody help me? Thanks for replying. Jefferson 附件

Jeff,您需要将分频器子电路cell10b1的仿真视图从“原理图”更改为“emModel”。
以上来自于谷歌翻译 以下为原文 Jeff, you need to change the simulation view for the divider subcircuit cell10b1 from "schematic" to "emModel". |

我对电路仿真日志消息的理解是运行Momentum仿真时出错。 您可能会在Momentum日志中看到更多详细信息。 手动启动时Momentum仿真是否正确完成? 以上来自于谷歌翻译 以下为原文 My understanding of the circuit simulation log messages is that there was an error when running the Momentum simulation. You might see more details in the Momentum log. Does the Momentum simulation finish properly when started manually? 附件

还有一个关于“接地”引脚的评论:接地参考的位置很重要,类似于真正的硬件。 您应将接地引脚放在靠近信号引脚的位置。 您也可以考虑使用定义尺寸的接地引脚:http://muehlhaus.com/support/ads-application-notes/edge-area-pins 以上来自于谷歌翻译 以下为原文 One more comment on your "ground" pins: the location of the ground reference matters, similar to the real hardware. You should place ground pins close to the signal pin. You might also consider using defined size for the ground pins: http://muehlhaus.com/support/ads-application-notes/edge-area-pins |

> {quote:title = jefferson90写道:} {quote}>我相信所有的引脚都在边缘。 >我正在用CPW传输线做功率分配器。 你可以看到我如何定义端口是的,我看到的是错误的。 接地引脚必须位于信号导体附近的边缘,不要像放置它们那么远。 接地电流将在导体边缘处流动。 放置引脚的位置会插入一个额外的路径长度。 对于错误消息,我认为这与接地引脚的放置有关(输出侧同一边缘上有多个引脚)。 您应该与Keysight支持部门联系以获取帮助。 以上来自于谷歌翻译 以下为原文 > {quote:title=jefferson90 wrote:}{quote} > I believe that all the pins are on the edge. > I am doing the power divider with CPW transmission line. You can see how I define the ports Yes, and what I see is wrong. The ground pins must be at the edge near the signal conductor, not so far away as you have placed them. The ground current will flow at the edge of the conductor, at the gap. The position where you have placed the pin inserts a large extra path length. For the error message, I think that is related to placement of ground pins (multiple pins on same edge on output side). You should contact Keysight support for help. 附件

> {quote:title = jefferson90写道:} {quote}>你说比其他港口的位置还差吗? 作为一名EM仿真专家拥有超过15年的经验,是的,所有的端口位置对我来说都是错误的。 以上来自于谷歌翻译 以下为原文 > {quote:title=jefferson90 wrote:}{quote} > Do you say than the other ports are badly located too? From more than 15 years experience as an EM simulation expert, yes, all ports placements look wrong to me. |
