问答对人有帮助，内容完整，我也想知道答案 0 你好，关于ADS 2102.08的非常基本的问题。想确保我做得对。 1.创建布局（Cell1），带有铜迹线和端口。在EM设置窗口中，将起始频率设置为1.8GHz，将频率设置为1.9 GHz。单击“立即创建”以获取emmodel和符号。 ADS是否正在进行EM仿真并计算S参数（当点击EM Model的“立即创建”时）？或者这个Em模型中有什么。它有EM仿真结果吗？ 2.创建一个原理图视图并拖动符号（From Cell1）。设置S参数模拟，Start Freq为1.8GHz，Stop为1.9 GHz。跑过模拟。在“选择模拟视图”中选择了“让层次结构策略确定”。 ADS很快完成了模拟。但是，我认为此时不使用EM模拟，对吧。 3.选择“将其用于模拟”并选择我的“EM模型”并从原理图视图中运行模拟。看起来ADS现在正在进行EM仿真。结果与步骤2不同。但是，我的布局中没有看到铜的任何网格划分？ 4.假设我改变我的原理图窗口S参数Start to 1.6GHz and Stop as 2Ghz（在EM设置中分别为1.8 Ghz和1.9 GHz）。当模拟视图从EM模型选择作为模拟视图运行时，它是否会在原理图视图中设置新频率时再次运行EM模拟？ 5.假设我在单元格1布局视图中对铜进行了一些更改并保存。如何确保在原理图视图和模拟结果中反映出这种变化？ 6.假设我在铜线上的布局视图中添加了另一个端口。如何确保它反映在原理图视图中？ 7.在EM设置窗口中，有一个“模式/符号”选项。然后在“EM”，“组件”，“创建模型/符号”下还有另一个。它们一样吗？以上来自于谷歌翻译以下为原文 Hello, Very basic question on ADS 2102.08. Want to make sure that I am doing it correct. 1. Created layout (Cell1) with a copper trace and ports. In the EM set up window, set the start frequency as 1.8GHz and Stop freq as 1.9 GHz. Clicked on "Create now" for emmodel and symbol. Is ADS doing the EM simulation and computing the S parameters at this point (When clicked the "Create Now" for EM Model)?. Or what is there in this Em model. Does it have the EM simulation results? 2. Created a schematic view and dragged the symbol (From Cell1). Set up the S parameter simulation with Start Freq as 1.8GHz and Stop as 1.9 GHz. Ran the simulation. The "Let the Hierarchy Policy determine" was selected in "Choose View For Simulation". ADS quickly did the simulation. But, I think the EM simulation is not used at this point, right. 3. Selected the "Use this for simulation " and selected my "EM Model" and ran the simulation from Schematic view. Looks like ADS is doing the EM simulation now. The results are different from step 2. But, I don't see any meshing of the copper in my Layout ?. 4. Suppose I change my schematic window S parameter Start to 1.6GHz and Stop as 2Ghz (In the EM set up it is 1.8 Ghz and 1.9 GHz, respectively) . When simulation is run from the schematic view with EM modele selected as view for simulation, will it run the EM simulation again with the new frequency set in the schematic view? 5. Suppose I make some changes in the copper in cell 1 layout view and save. How to make sure that this change in reflected in the schematic view and in my simulation results? 6. Suppose I add another port in the layout view on the copper. How to make sure that it is reflected in the schematic view? 7. In the EM set up window, there is an option for "Mode/symbol". Then there is another one under "EM","Component","Create Model/Symbol". Are they same? 0

答案对人有帮助，有参考价值 0 你好Leyo！ > {quote：title = Leyo写道：} {quote}> 1.创建布局（Cell1），带有铜迹线和端口。在EM设置窗口中，将起始频率设置为1.8GHz，将频率设置为1.9 GHz。单击“立即创建”以获取emmodel和符号。 ADS是否正在进行EM仿真并计算S参数（当点击EM Model的“立即创建”时）？或者这个Em模型中有什么。它有EM仿真结果吗？对于在此布局上运行的EM仿真，emModel将管理EM结果。如果布局单元格具有参数，则emModel还将管理不同的结果，以及这些EM结果之间可能的插值。您可以在运行EM模拟之前或之后创建emModel。如果在运行EM仿真之前手动创建它，它将在原理图需要数据时自动启动EM仿真。 > 2.创建一个原理图视图并拖动符号（From Cell1）。设置S参数模拟，Start Freq为1.8GHz，Stop为1.9 GHz。跑过模拟。在“选择模拟视图”中选择了“让层次结构策略确定”。 ADS很快完成了模拟。但是，我认为此时不使用EM模拟，对吧。正确。 > 3.选择“将其用于模拟”并选择我的“EM模型”并从原理图视图中运行模拟。看起来ADS现在正在进行EM仿真。结果与步骤2不同。但是，我的布局中没有看到铜的任何网格划分？正确。这已经开始了EM模拟。如果从emModel运行EM仿真，则不会看到网格。如果要查看网格，可以从emSetup生成它（右下角：将下拉列表从“S-Parameters”更改为“Mesh”并单击“Go”）> 4.假设我更改了我的原理图窗口S参数开始时为1.6GHz，停止为2Ghz（在EM设置中分别为1.8 Ghz和1.9 GHz）。当模拟视图从EM模型选择作为模拟视图运行时，它是否会在原理图视图中设置新频率时再次运行EM模拟？没有！无论您在原理图中配置了什么，它都将继续使用emModel中配置的频率！您将看到有关数据外推的警告，但是否则没有自动行为来调整emModel / emSetup频率。安捷伦支持称这是故意的，因为您可能希望在非线性模拟中将您的布局EM高达n次谐波，并且用户应该更好地手动设置所有这些。我对此并不完全同意，但事实就是如此......关于emModel和emSetup的一条评论：emModel是从emSetup设置创建的，并创建了这些设置的“快照”。因此，在创建emModel之后，它会有自己的独立设置，直到从emSetup更新为止。如果您手动更新它，或者在启用了自动emModel更新的emSetup对话框中进行EM模拟后，它只会从emSetup更新。 > 5.假设我在单元格1布局视图中对铜进行了一些更改并保存。如何确保在原理图视图和模拟结果中反映出这种变化？你需要小心！如果您手动编辑布局，则ADS无法识别您的布局更改。您需要从emSetup手动启动EM仿真，并启用emModel的自动更新。这将覆盖以前的结果。或者，您可以使用问题（7）中的菜单项手动更新emModel和符号。如果布局是参数化单元格，并且布局由于单元格参数更改而自动更改，则emModell 将识别此并为此参数组合添加另一个设置结果。 > 6.假设我在铜线上的布局视图中添加了另一个端口。如何确保它反映在原理图视图中？打开emSetup对话框。在Model / Symbol页面上，启用symbol和emModel的自动更新，并启动EM模拟。或者，您可以使用问题（7）中的菜单项手动更新emModel和符号。 >> 7.在EM设置窗口中，有一个“模式/符号”选项。然后在“EM”，“组件”，“创建模型/符号”下还有另一个。它们一样吗？是的，那是一样的。最好的问候Volker 以上来自于谷歌翻译以下为原文 Hello Leyo! > {quote:title=Leyo wrote:}{quote} > 1.

Is ADS doing the EM simulation and computing the S parameters at this point (When clicked the "Create Now" for EM Model)?. Or what is there in this Em model. Does it have the EM simulation results? The emModel will manage your EM results, for the EM simulations that you run on this layout. If the layout cell has parameters, the emModel will also manage the different results, and possible interpolation between these EM results. You can create the emModel before or after running the EM simulation. If you create it manually before running the EM simulation, it will start the EM simulation automatically when the schematic needs data. > 2. Created a schematic view and dragged the symbol (From Cell1). Set up the S parameter simulation with Start Freq as 1.8GHz and Stop as 1.9 GHz. Ran the simulation. The "Let the Hierarchy Policy determine" was selected in "Choose View For Simulation". ADS quickly did the simulation. But, I think the EM simulation is not used at this point, right. Correct. > 3. Selected the "Use this for simulation " and selected my "EM Model" and ran the simulation from Schematic view. Looks like ADS is doing the EM simulation now. The results are different from step 2. But, I don't see any meshing of the copper in my Layout ?. Correct. This has started the EM simulation. You don't see the mesh if you run the EM simulation from the emModel. If you want to see the mesh, you can generate it from the emSetup (bottom right: change the dropdown list from "S-Parameters" to "Mesh" and click "Go") > 4. Suppose I change my schematic window S parameter Start to 1.6GHz and Stop as 2Ghz (In the EM set up it is 1.8 Ghz and 1.9 GHz, respectively) . When simulation is run from the schematic view with EM modele selected as view for simulation, will it run the EM simulation again with the new frequency set in the schematic view? No! It will keep using the frequencies that are configured in the emModel, no matter what you have configured in the schematic! You will see a warning about data extrapolation, but otherwise there is no automatic behaviour to adjust the emModel/emSetup frequencies. Agilent support say this is on purpose, because you might want to EM your layout up to the n-th harmonic in nonlinear simulations, and the user should better set all this manually. I don't fully agree on that, but it is what it is ... One comment on emModel and emSetup here: the emModel is created from the emSetup settings, and creates a "snapshot" of these settings. So after you have created the emModel, it has its own independent settings until it is updated from the emSetup. It is only updated from the emSetup if you update it manually, or after an EM simulation from the emSetup dialog with the automatic emModel update enabled. > 5. Suppose I make some changes in the copper in cell 1 layout view and save. How to make sure that this change in reflected in the schematic view and in my simulation results? You need to be careful here! ADS does not recognize your layout changes, if you manually edit the layout. You need to manually start EM simulation from the emSetup, and enable automatic update of the emModel. This will overwrite previous results. Or alternatively, you can manually updated emModel and symbol with the menu item from your question (7). If the layout is a parameterized cell, and the layout changes automatically because the cell parameters change, then the emModell will* recognize this and add another set up results for this parameter combination. > 6. Suppose I add another port in the layout view on the copper. How to make sure that it is reflected in the schematic view? Open the emSetup dialog. On the Model/Symbol page, enable the automatic update of symbol and emModel, and start the EM simulation. Or alternatively, you can manually updated emModel and symbol with the menu item from your question (7). > > 7. In the EM set up window, there is an option for "Mode/symbol". Then there is another one under "EM","Component","Create Model/Symbol". Are they same? Yes, that's the same. Best regards Volker
