Print Noise Summary after "ANALYSIS DURING TRAN"

msharma

Hi,

I need to simulate the noise of my circuit at specific points in time after transient analysis. For this I use the "ANALYSIS DURING TRAN", (analysis->tran->options-?output->"ANALYSIS DURING TRAN"). I specifiy a time in actimes, and specify acnames = noise. The analysis runs successfully. However, I am unable to use the "Print Noise Summary" feature. When choosing Print Noise Summary, no dialog pops up, just an empty result window.

How can I use the "Print Noise Summary" feature when running noise analysis at specific tran points?

Thanks,

Mohit

  • Hi Tawna,

    Thanks for clarifying a potential confusion in terminology (looks like I don't have access to the support portal). However, I am not running transient noise analysis. I am simply running noise (and stb and ac) analyses at specific timepoints. All I am interested in is small signal behaviour once the circuit is in a steady state. Thus, I use acnames, and actimes feature of the tran analysis. However, the analysis results are not accessible through "Results" menu in ADE. They are only accessible through "Results Browser" (e.g. "Results"->"Direct Plot"->"Equivalent Output Noise" doesn't plot anything, and CIW logs "*Warning* no noise results, can't plot equivalent output noise.").

    That works for most of my needs. But when trying to sort noise contributions, I need to use the "Results"->"Print"->"Noise Summary". Is it possible to understand why the small signal results are not available with the actimes feature?

    Thanks,
