請(qǐng)問個(gè)關(guān)于CST和ADS協(xié)同仿真的問題
在使用static link協(xié)同仿真時(shí)候有個(gè)問題想請(qǐng)教一下
按照手冊(cè)上說的先建立1D results template> ADS COMPONENT EXPORT,
然后做了parameter sweeping就2個(gè)sample點(diǎn),打算使用file > EXPORT >AGLIENT ads component 導(dǎo)出測(cè)試以下,
可是AGLIENT ads component 變成灰色不可點(diǎn)擊,可是result folder里面的產(chǎn)生了.mdf 文件阿,請(qǐng)問這是什么原因
多謝
最好仔細(xì)閱讀一下CST幫助文件《Export Agilent ADS Component》,看看有沒有什么地方?jīng)]有滿足要求:
There are a few rules and limitations that must be considered when using the Agilent ADS® component export:
1. The ports must be numbered subsequently. This means that a port numbering of 1, 2, 3, ..., N will be fine, but there must not be any ports numbers missing in between (e.g., 1, 2, 3, 4 is valid, but 1, 3, 5 is invalid).
2. All S-parameters (the full S-matrix) must be calculated.
3. Currently only up to six ports (including multiple port modes) are supported.
4. Currently only up to nine varying parameters are supported. Parameters depending on other parameters are not counted as well as parameters that are not varied within the current result data file.
.mdf文件是建立并運(yùn)行1D Result Template: ADS Component Export之后就會(huì)生成的,和Export Agilent ADS® Component無關(guān)。
你列出的那些點(diǎn)我都注意到了在手冊(cè)里,肯定不是那些的問題,我已經(jīng)查過很多次了。如果不做parameter sweeping 我的static link可以工作,沒問題。但是一旦做了parameter sweeping, 1D results 里面沒有結(jié)果,結(jié)果會(huì)在table里面顯示,這時(shí)我再想導(dǎo)出Export Agilent ADS® Component就不可以了。
。mdf 文件里面有仿真結(jié)果,執(zhí)行導(dǎo)出就是將其拷貝并移植到cst library 目錄circuit folder 下面
真不知道你是怎么“注意”的,第二條里寫的那么明白:所有的S參數(shù)都要被計(jì)算到!你做了PS之后,參數(shù)都保存在table里,1D results里沒有結(jié)果,你自己不都已經(jīng)注意到了嗎,這就不符合第二項(xiàng)要求,當(dāng)然不能導(dǎo)出了……。
謝謝hefang的幫忙,說話有不妥之處還請(qǐng)見諒。
還有點(diǎn)不明白就是 手冊(cè)里面提到**parametric access** of previously computed S-parameter data。 我的理解是做了parameter sweeping后還可以繼續(xù)導(dǎo)出結(jié)果的,不知道我的理解對(duì)不對(duì)。而且我看到project folder 里面results 目錄里面的sparameter.mdf文件在PS后也會(huì)被更新過。如果static link 不可以導(dǎo)出PS的結(jié)果,那么每次的導(dǎo)出只是一次簡(jiǎn)單full ports 的SNP文件的導(dǎo)出,那static link的意義又在哪里呢?
Export Agilent ADS Component (File Export Agilent ADS Component). This option creates a component for use in the Agilent ADS schematic view based on the current mode. The component allows for * *parametric access** of previously computed S-parameter data.
嗯,再仔細(xì)來分析一下。先聲明我并沒有用過這個(gè)功能,所以我只是根據(jù)幫助文件上的內(nèi)容紙上談兵。
先理解"Static Link"的意義。幫助文件里"Static Link"這個(gè)概念是用來和"Dynamic Link"做比較的??纯丛摹禔gilent ADS® Co-Simulation Overview》:
Static Link: The ”static” link (ADS® 2003A and above) requires parametric CST MICROWAVE STUDIO® results to be computed before the component is used within ADS®. The results are written into a local database which is then interpreted by the component. The circuit simulator automatically interpolates the S-parameter between the pre-computed samples. The static link can be used for structures with up to 6 ports.
Dynamic Link: Moreover, the ”co-simulation” alternative enables ADS® to launch CST MICROWAVE STUDIO® in order to automatically calculate required data. All information is stored together with the CST MICROWAVE STUDIO® model to avoid unnecessary repetitions of lengthy EM simulations. The co-simulation interface requires ADS® 2005A or above.
原文的意思應(yīng)該是:靜態(tài)連接(Static Link)時(shí)需要的全部S參數(shù)矩陣結(jié)果必須提前計(jì)算好,相對(duì)應(yīng)的動(dòng)態(tài)連接(Dynamic Link)是在需要計(jì)算的時(shí)候再調(diào)用MWS計(jì)算需要的數(shù)據(jù)。這個(gè)類似于DS和Transient Co-Simulation。
好,接下來看看在Static Link里使用參數(shù)掃描(Parameter Sweep)。按照幫助文件《Agilent ADS® Co-Simulation Overview》里的描述,Static Link和Dynamic Link是可以使用參數(shù)掃描的:“Once the result template is defined, you can run simulations for various parameter settings.”也就是說,1D Resutl Template里面定義的ADS Component Export是包括了參數(shù)掃描信息在內(nèi)的。不過,在幫助文件《Export Agilent ADS Component》里也列出了我在1樓里列出的那四項(xiàng)要求。
參照第二項(xiàng)的要求,我想問小編:你在參數(shù)掃描的時(shí)候所有的端口都計(jì)算到了嗎?也就是說,參數(shù)掃描的時(shí)候你計(jì)算的是感興趣的某一(幾)個(gè)端口還是所有的端口?
首先,我使用的一個(gè)固定的mesh cell數(shù)目,然后我將simulation settings里面設(shè)置為all port and all mode, 然后去做parameter sweeping,reslt watch 里面只用postprocessing data...點(diǎn)擊edit可以看到ADS Component Export.
這是我使用環(huán)境,是不是哪里有問題呢?
