图 1. 9 工艺库文件的选择 在文件浏览器中选定需要的文件之后点击 ok 按钮,文件的路径就会自动填在 Model 18 Library File 栏,这时点击 Add 按钮,这个库文件就被加入到中间的列表中。这时,既可以 继续添加新的模型库文件,也可以在模型库文件列表中选择一个或几个对其做禁用、启用、 修改或删除操作。 3 . ...
图 1. 8 工艺库文件设置 在这个窗口中可以在“Model Library File “栏输入需要使用的模型库文件名,在Section 栏 输入该模型文件中需要的段(Section) 。 如果模型库文件名路径比较长,可以点击右下角的“Browse “按钮。打开Unix 文件浏览器 查找需要的模型文件。文件浏览器的使用方法就不再介绍了。 图 1. 9 ...
在ADE窗口中,选择Analyses→Choose…,弹出对话框,从对话框中选中“noise”选项。噪声仿真同样可以进行“Frequency”“Design Variable”“Temperature”“Component Parameter”“Model Parameter”这些参数扫描。“noise”设置对话框如图3.27所示。 以对频率“Frequency”进行扫描为例,如图3.27所示,此时“Sweep Range”是电路的...
默认值为1。 2.MODEL OPTION语句: SCALE影响器件参数,如:L、W,area, SCALM影响model参数,如tox、vto、tnom。 格式为:.option scale=1u Options Keyword Application Table 仿真控制和收敛 造成Hspice仿真不收敛主要有’‘No Convergence in DC Solution’‘和’‘Timestep too Small’‘,其可能的原因是: 1....
Unless I don’t know what’s really going on in Cadence PAC sampled, it’s hard for me to do an equivalent Matlab model of this simple sampled RC low pass filter, but that’s another story, and in order that it is not confusing for othe...
(续):.optionnomod表达不输出MODEL参数,以便减小列表文件旳大小;.optionbrief=1表达不输出网表信息,直到设置.optionbrief=0,NXX同brief;.protect/.unprotect用于屏蔽网表文件中要保护旳信息;.optionbypass=1不计算latent器件;.optionautostop表达当全部.meas语句完毕时,终止仿真;.optionaccurate=1表达设置为最精确旳...
as they dictate the temperature and energy transfer at the model's edges. These boundaries might function either as a heatsink, which dissipates heat, or as an insulator, which retains it. In scenarios where the model is surrounded by air, the presence and flow of air become significant fac...
Transfer function for time/frequency domain conversions as well as amplification for op-amp network and circuits of similar functionality. Digital-Digital circuitsmodel in a more abstract fashion. As digital circuitry can have a more direct implementation of software operating devices like microcontrollers...
Thermal simulations for electronics in an enclosure need boundary conditions and source definitions based on temperature measurements. Read Article Power Supply Control Loop Transfer Function Construction Power supply control loop transfer function can be determined from the output impedance of the power s...
This usage model reveals a technology gap in the platform I/O space, yielding an inflection point of opportunity. The eUSB2 Version 2.0 (eUSB2V2) is developed to deliver a scalable I/O technology specifically designed for inside-the-box (embedded) USB applications, optimizing for ...
