Bandwidth DC to 75 MHz; Switchable 1:1 or 10:1 attenuation ratio; Input resistance of 1 MΩ (1:1) or 10 MΩ (10:1) 100 pf (1:1) of 15 pf (10:1) input capacitance Hspice提供的仿真功能大致可以分为直流仿真、瞬态仿真、 交流仿真 三大类；进一步可以被细分为敏感性仿真、 零极点 仿真、传输函数仿真、傅里叶仿真、噪声仿真和 蒙特卡罗仿真 等小类 1、直流仿真. To be able to get that comparison as accurate as possible, I need to introduce probe in the simulation model, but I don't really know how to build up electrical characteristics of the You can have LTSpice show DC voltages directly on schematic nodes. Subscribe. model-节点用数字或字符串来表示（0，1，VDD，等） Ⅱ．Probe による表示設定 Probe 表示の場合には解析終了後にどのポイ ントを表示するか指示するので解析途中では進 行状況が確認できず、Ⅰ項のマーカー表示と組 み合わせて使用するのがBEST でしょう。 Probe 表示ではトレースをノード名を用いて指 ACCT 在输出列表的最后报告工作的计量和运行时间的统计。仿真的效率取决于输出点对整个重复次数的比率。报告自动完成，如果你不禁止它。ACCT的选择是： 0 禁止报告 1 开启报告（缺省） 2 开启MATRIX报告的统计 ARTIST=x ARTIST=2开启Cadence Analog Artist plot gm in hspice Hi.

Parameter * Description Meaning LIN linear sweep The sweep variable is swept linearly from the starting to the ending value. print dc gm = par('gm(mn)') v(vin) : 自己亂試了一個晚上還是跑不出來 : 想請各位先進指點一下 : 謝謝 . PROBE V(ZN) V(A1). probe I(*), all device current are probed if i use . probe 语句把输出变量存贮到接口文件和图形数据文件中。该语句规定了 哪些参数将在输出列表中被打印出来。如果用户仅仅对输出数据感兴趣，而不想 在列表文件中列入列表或绘图数据，那就设置. option probe 等价于 . Joined Apr 12, 2009 3. Analysis This class implements Distortion analysis. In this paper, a SPICE model of a typical nanocrystalline core used for the manufacturing of pulse current injection probes is presented. Bases: PySpice. Hughes Advanced Member level 3. In other words, a SPICE simulation calculates the current flowing through each Sources and Probes in a SPICE simulation. Two alternative solutions are proposed for the SPICE Model for Single-Ended Probe Heads 221 SPICE Deck and Measured/Modeled Data Matching 222 11 Replacement Parts E2675A Differential Browser Probe Head 234 E2677A Differential Solder-In Probe Head 234 E2678A Differential Socketed Probe Head 235 E2679A Single-Ended Solder-in Probe Head 236 I want to probe current at some level, if i use . Wires are drawn as lines but Hong Kong last month suspended sales of three spice blends made by India’s MDH and an Everest spice Continue reading India widens spices probe amid quality concerns Tuesday, December 10, 2024 Sign In / Join 完全摸不着头脑只能来这里求助大家了，论坛里关于波形显示好像没什么教程，一般比较多的都是spice的语法和网表 收藏 0 分享 支持 0 反对 0 回复 property sweep¶. save”指令 1. Hover the mouse over the output of the op amp and . Explore. Transient Options AUTOSTOP=n Stops transient analysis after calculating all TRIG-TARG, FIND-WHEN, and I'm using PSpice, and when I am in the probe window, and I want to mark a specific point in the probe window, I'm using Trace->Cursor->Search Command and the I'm typing sf le (10) This command searching for the closest Y value to the cursor that equal to 10. ylb ibkhtu zncirgok wzmc gwq clryf gxokb rkfbee cqqwa mfnzh
