how to use user defined digital pattern as an input

esha123

 im using candene virtuoso.Is it possible to define my own input pattern (e.g 101100011) instead of using "vsource" as an input to inverter.. i need to estimate  power for different input patterns of my own choice.plz give suggestion how can i do it only using virtuoso. !!!

Thanks..!!

  • 1. What version of spectre are you using?  Typing the command in an xterm at the unix prompt:

    unix> spectre -W

    will give that information.

    2. Look at the contents of spectre help:

    unix> spectre -h vsource

    --or--

    The SpectreRF User Guide has the information that you need.  You should be able to access it by calling up the documentation:

    unix> cdnshelp

    Alternately you can look at the pdf document with acroread, type in an xterm

    unix> which spectre

    This will return the path to spectre:

    unix>  /grid/cds/software/MMSIM131ISR/tools.lnx86/bin/spectre

     Now you know where your spectre software hierarchy is located, cd to

    unix> cd  /grid/cds/software/MMSIM131ISR/doc/spectreRF

    This is the location of the documentation in the hierarchy (if you cannot find it installed on your machine)

    Open the SpectreRF documentation with acroread:

    unix> acroread spectreRF.pdf

     

    If you are using MMSIM12.1-13.1, the information is in Chapter 8: AnalogLib Components Used in RF Simulation of the SpectreRF User Guide.   Look for port.  Many of the properties on port are the same as those in vsource and isource.

    There's no substitution for opening a schematic, putting in the source, running simulations, and looking at what the various options do, especially if you are a new user.   (But the documentation is pretty good.)
