Title: PPV values from pss/pnoise simulation in spectreRF
Post by nrk1 on Dec 28^th, 2015, 10:54pm

I read an old presentation on "Noise aware PLL plugin" (https://www.cadence.com/rl/Resources/conference_papers/ctp_cdnlivesv2007_Thibieroz.pdf). Apparently this has been discontinued. Anyway, in the presentation, it says that perturbation projection vector(PPV) values are stored in the simulation results directory(slide 17). Is this true of a regular pss/pnoise simulation in SpectreRF? If so, how would I make it save the PPVs and access the results? (SpectreRF certainly calculates all these, but I don't know how to access these)

Just in case someone else is interested in this. I discovered that there is an enable ppv option in pnoise which saves this data(accessible from results browser). Somehow I had overlooked this before.

Hello nrk1

Thank you for the information. Is this option also available from ADE-L pnoise analysis?

ADE L is what I used. (What is the alternative? )

Setting ppv=yes in the spectre analysis statement for pnoise
