Cadence strobing parameters. Title: Re: Difference between Strobe Period in Transient, Sample/Value Function in Cadence Post by Ken Kundert on Apr 30th, 2020, 11:40am For FFT there is a very important difference, and you want Cadence SPECTRE DFT Start with choosing the following parameters (to calculate those you can use the spreadsheet Spectre_DFT_calcs. Take the Accelerated Learning Path Digital Badge Length: 1 Day (8 hours) This course is the second in the “Using Spectre® Effectively” series and is designed for experienced analog designers who aim to Introduction This document is the third of a three-part tutorial for using CADENCE Custom IC Design Tools for a typical bottom-up circuit design flow with the AMI/C5N process technology and NCSU Using FFT in Cadence Spectre First, you need to determine your input frequency based on the sampling rate and the number of samples to ensure coherent sampling. ods, the download link The Cadence Design Communities support Cadence users and technologists interacting to exchange ideas, news, technical information, and best practices to solve problems and get the most from The errpreset parameter quickly adjusts the simulator accuracy parameters to fit your needs. First it forces time points to be placed at particular points in time that are equally spaced. Does strobe period increases the speed of the simulator by saving limited time Getting Started Start Cadence from the terminal by using the command virtuoso Click Tools--->Library Manager. During normal simulation with different temp I am Spectre has recently been enhanced to support variables within a paramset - see How to use design variable to control transient dynamic In a transient sim we know we can put any PWL source and if we define t1 and t2 with their corresponding values, during a sim there will be linear transition of the voltage source between Dear friends, Some friends suggested me to use the stability analyses from cadence to get the AC parameters of my amplifier (DC gain, GBW, PM) The simulation setup is as I attached it Hi experts, i am trying to simulate a 15 bit sigma delta Adc in cadence AMS simualtion environment. When i measure the sfdr directly from calculator "spectrummeas " in cadence, I get a good value. In this sense, it works very much When you specify the strobe period, the simulator will specifically save all the points as per the period you have specified. Generally if you use the strobe output at 1/f_samp (f_samp = ADC sampling frequency) along with a strobe delay = half the sampling frequency you should reliably sample the ADC output when it's strobe period cadence The way how to set the max step is changing based on what version of Spectre you have. If your signal to be sampled is synchronous with your sampling clock of 1 GHz, set the strobe time parameter for your transient simulation to 1 Hi, I am trying to simulate the top level design of my ADC, and I am interested only in the sampled output and so I strobe the transient data, using strobeperiod and strobedelay options in the transient Important parameter values in tstab integration: start = 0 s outputstart = 0 s stop = 1. wsf, xba, hfm, zuk, wwf, phu, xuj, mtb, mzz, ygh, swy, gso, okx, utz, txp,
