Title: how to use ADE's pnoise to simulate clock jitter Post by mjun0mjun on Dec 6th, 2011, 12:14am Dear all, I want to simulate the clock jitter using ADE's pss and pnoise. The simple test schematic is shown in schematic.JPG. And pps and pnoise options are shown in the next two figures, pss.JPG and pnoise.JPG. The pnoise output graph is shown in the last figure, pnoise_simresult.JPG. The problem is that, I don't know the meaning of the pnoise output graph. I expected it would show me some explicit information about jitter. Now I don't know how to calculate the clock jitter from the pnoise output graph. And even is the pnoise output graph right? Thank you~~ majun |

Title: Re: how to use ADE's pnoise to simulate clock jitter Post by Frank Wiedmann on Dec 6th, 2011, 1:17am You can get jitter values by selecting Results -> Direct Plot -> Main Form in ADE and selecting pnoise jitter as Analysis. You might want to read the thread starting at http://www.designers-guide.org/Forum/YaBB.pl?num=1224609785 (and the references mentioned there) for some background information. |
