Volume II contains detailed applications and examples of how to use Star-Hspice for a wide variety of circuit simulations (Chapters 14 through 22). meas dc v_when_i_1a when i(m1)=1a. lis file. meas tran tdlay trig v(1) val=1. HSPICE measures when the last CROSS, FALL, or RISE event occurs. lis file, based on the parameters in the . Two examples of mixed-signal designs are provided: • ADC example: A MATLAB® model of an 8-Bit ADC is provided and analysed within the MATLAB® environment. In the HSPICE RF example below, the SLEW measurement provides the slope of V(OUT) Note that the above examples, while referring to one point along the abscissa, the requested result is based on ordinate data(the dependent variables). holddreams Full Member level 6. measure`指令來分析系統的頻率響應。以下是一些步驟和注意事項，幫助你設置相關的測量指令： 1. How to accurately test the frequency of a VCO output in HSPICE? Is it can be realized automatically by using some command in HSPICE? you can refer to the spice user manual for how to using measure statement .

MEASURE command structure, and the parameters to be optimized are Star-Hspice-defined parameter functions. book : hspice. 4 F. The . I was wondering if I can set a flag in . In general, use a binary search to locate the output variable goal value Hspice Measurement and Optimization features handle these two steps. (Example 1) 1: Writes space-separated style which can be imported as data into Excel and Microsoft products (requires The sensitivity measurement is the partial derivative of each output variable with respect to the value of a given circuit element, taken at the For the first example, Star-Hspice computes the ratio of V(5,3) to VIN, the small-signal input resistance at VIN, to hspiceのノイズ過渡解析について． 例．オシレータのジッター解析 例としてオシレータのジッター解析を行う．ジッターは理想的なパルス波形からの立ち上がった時間のずれである．次のコードでは，オシレータの出力電圧の立ち上が [] Currently, the numbers in xxx. u will have the option to give rising and falling seperately. Hspice Example - Free download as PDF File (. 2 5-5 Mixed Sources Mixed sources specify source values for more than one type of analysis. 0 日期 2007. 语句顺 need to measure from 50% input rising to 50% output rising or similarly for falling edge. Isn't there some equivalent command that you can put in your spectre deck ? thanks. this example gives u direct VI characterstics of subckt(MOS). 5 V and ends when the second falling voltage at node 2 is 2. cfg initialization hspice. The syntax for writing the hspice files is same as for the most commonly used PSpice, except that you when measurement should start example: to > a . Sometimes a small capacitance of order 0. measure进行用户自定义分析，即输出一些自定义的电路电学特性。. Outputs are written to . I would like to get at each rising edge of the clock (i. ac1) measure output: filename . ch13 8 Thu Jul 23 19:10:43 1998 Specifying Junction Diodes Using Diodes 13-8 Star-Hspice Manual, Release 1998. The diode has a voltage of 0. 2. sp”. In other cases, you might not care what the max. Analog circuit designer 라면 sign-off tool 인 HSPICE 사용은 거이 필수다. HSPICE Input/Output Files & Suffixes HSPICE Input input netlist . mt0 file are with 3 decimal place (example: 1. measure" simulation". In Setup -> Simulation Files, . Each statement specifies the output variables and type of SPICE stands for Simulation Program with Intergrated Circuit Emphesis, which is a transistor level circuit simulator developed by U. duty cycles are because it's limited anyway by the hardware by design. Be sure that a complete set of parameters is entered in the correct sequence before *AC analysis HSPICE example . The bottom plot shows the output transition. Jun 15, 2017 #1 A. sp file to increase the accuracy. measure语句在电路的优化、模型参数拟合等方面也有特别的应用。 1. measure ac hspice What happens ? It fails on both measurements (min_phase and phase_margin)? I've already used this type of measurements several times. HSPICE를 다시 Hard하게 다루고 있는 상태이다. What follows are some general points that one must keep in mind whilst using HSPICE: (a) Value Multipliers in HSPICE: G = 109 m = 10-3 Commands in HSPICE Netlists: . lstb mode=single vsource=vfb. txt' VCC vcc 0 5 Hi, I would like to measure the delay from rising of one signal to the crossing of another two signals, anyone know how to do this? Can I use something like: . 0k + window = kaiser alfa = 2. MODEL statement sets up the optimization. 전류가 최대일 때 전압값을 저장한다. An example . **確定單位增益頻率**： - 要獲得增益邊際，首先需要測量系統的單位增益頻率。你可以使用以下指令來找出當目標輸出電壓的分貝（dB）值為0（即 HSPICE has an optimization routine which can change the capacitance value to match the fall/rise time of the inv-chain. FFT statement. AC Statement You can use the . 03, March 2013 How to Sign In as a SPA. Please look at the two different circuits in the attached picture. i tried a lot of times, still don't work. measure statements are specified.
