在Data Access Component(DAC)方面需要帮助

我有一个漏极电流值= f(栅极电压,漏极电压)的值表。
我想使用DAC读取这些漏极电流值,并根据栅极电压和漏极电压拟合它们。
请让我知道如何解决这个问题:1。我的数据应该采用什么文件格式?
2.请解释我应该在DAC中的自变量和插值参数属性中设置的内容。
3.我试图通过DAC读取这些值,并使用符号定义设备(SDD)将它们作为输入馈送到大信号模型。
谢谢

  I have a table of values of Drain Current = f( Gate voltage, Drain Voltage ). I want to use the DAC to read these drain current values and fit them as a function of the gate voltage and drain voltage. Please let me know how I can go about this :

1. What file format should my data be in ?
2. Please explain what I should set in my independent variables and Interpolation Parameters properties in the DAC.
3. I am trying to read these values through a DAC and feed them as an input to a large signal model using a Symbolically Defined Device ( SDD ) .  

Thanks

您好,我是工厂的EEsof支持AE。
请首先考虑向EEsof支持热线eesof_support@keysight.com(或1-800)发送您的目标数据以及有关您的终极模拟目标的更多详细信息(您想要使用的大型信号模拟器:谐波平衡,瞬态等)。
美国的-473-3763)。
ADS支持团队可以直接帮助您解决具体示例中的任何具体问题。
但总的来说,我会考虑将您的IV数据导入为通用MDIF,如以下示例所示:** ADS导入通用ASCII CSV测量数据,如EasyExpert B1500 DC IV扫描数据作为MDIF文件数据文件工具或DAC http:// edadocs
.software.keysight.com / x / Eo7XDQ如果您还没有这样做,我会看一下ADS示例/ Tutorial / SDD_Examples。
这些可能适用于包括您在内的许多应用。或者对于某些更高级的DAC / SDD示例,您可能会发现这些示例也很有用:** ADS IC-CAP示例DAC仿真直接模拟IC-CAP测量的扫描偏置S参数ds

  Hello,

I'm an EEsof support AE in the factory. Please first consider sending your target data and more details about your ultimate simulation goals (what large signal simulator do you want to use: Harmonic Balance, Transient, etc..) to the EEsof support hotline eesof_support@keysight.com (or 1-800-473-3763 in the US).  The ADS support team can directly assist you with any specific questions you have in the context  of your specific example.

But in general, I would consider importing your IV data as Generic MDIF as shown in the following example:

** ADS Import Generic ASCII CSV Measured Data Like EasyExpert B1500 DC IV Swept Data as MDIF File Data File Tool or DAC
http://edadocs.software.keysight.com/x/Eo7XDQ 

If you have not done so already, I would look at the ADS examples/Tutorial/SDD_Examples.  These might be suitable for many applications including yours..

Or for some more advanced DAC/SDD examples, you might find these examples useful too:

** ADS IC-CAP Example DAC Simulation Directly Simulates IC-CAP Measured Swept Bias S-parameters ds Dataset File
http://edadocs.software.keysight.com/x/aob0Dw 


** Modeling a Nonlinear Capacitance Using a Symbolically Defined Device

Mark
