Create a new model file under " $CDK_DIR/models/spectre/nom " such as " ami06_t99j.m ". In the first line of the file, type " simulator lang=spice ". From the Wafer Electrical Test Data report (for T99J), copy the SPICE model parameters and paste them to the end of the new model file. S ...
link : http://ece451web.groups.et.byu.net/cadence-help/cadTOmat.html This file describes the process of outputting data from Cadence to Matlab. First, the data from Cadence must be written to a file. Then, Matlab can import the data from the written file. This tutorial ...
Simulation data generated by a simulator integrated with the Cadence Analog Design Environment, raw or post-processed, can be printed to text files using the print or printvs command. But if the data size is very large, Cadence will suggest the ocnPrint command which can be executed from the C ...

Q: We can see the parameter Vdsat in Cadence Spectre after we perform. the DC simulation. But I can't figure out what's the physical meaning of it? I guess the vdsat is the overdrive voltage at first, but it's not exact the same as Vgs-Vth. The Vdsat is smaller than Vgs-Vth. So anyone has th ...
How do I reload .cdsenv file in CIW type envLoadVals(?envFile "./.cdsenv") This will reload .cdsenv in the currect directory. You can change the path if desired.
For AWD there's a private function: awviSetLogicLevels(1.0 4.0) which sets the low and high voltage levels - but it's private. However, since AWD is going away in IC610, I don't see much danger in using it... For wavescan there's cdsenv settings: Code: wavescan.trace dToAHiVoltage string ...
如果用cadence安装文件夹下的默认设置，有些设置很不喜欢。 最最讨厌的是plot出来的线条的LineThickness是fine，很细，看起来很不爽。 Q: How can i set the default line type in the wavescan no matter which PDK i am using? A: You can refer to the "trace variables" section of wavescan manual by click ...
Q1: how to plot Vth versus L i.e. MOS threshold voltage variation versus channel length for different channel lengths. How can I do this in cadence spectre ? A1: In Analog Artist, you may add an output expression OP("/M1" "vth") to plot the vth of M1. Q2: Is this method good for ...
