Simulatiuon result analysis
May 18th, 2011, 2:29pm
 
Hello,

I am designing a serial TRX system and I need to observe/analyze the jitter profile in different locations of the link. My question is as the following:

- is there any way to plot the jitter histogram doing Spectre transient simulations ?
- if yes, is there any analytical way to evaluate the DJ/RJ parts ?


Thanks,

SATurn

Hi SATurn,

What tool version do you use? There is jitter analysis feature in IC 6.1.5.xxx.

Otherwise please look at http://www.designers-guide.org/Forum/YaBB.pl?num=1293197122.

Those tools and scripts are used to analyze jitter histogram after you finish a transient analysis. So it is used to measure DJ.

For RJ, I think you must run PSS/PNoise analysis with time domain noise. Please look at http://www.designers-guide.org/Analysis/PLLnoise+jitter.pdf.

Best Regards,
Yawei
