Title: SpectreRF pnoise Save Options
Post by Bradford Hunter on Sep 28^th, 2013, 9:28am

I am running SpectreRF on a switched capacitor integrator to find the input referred electronic noise. I need to post process the noise through a decimation type filter to find the total integrated noise at the output of a data converter. I need to save about 200k data points (linear) from 0 to 50 MHz. I run a pss analysis followed by a pnoise analysis. The results look about right but I can't save more than 1k data points without the simulation time exceeding 24 hours. I believe the issue is that the pnoise analysis wants to save noise information for each transistor in the design, for which there are hundreds. Despite trying every save option imaginable, I cannot seem to get pnoise to stop saving information for each transistor. I only need the "in" noise data points at the top-level of the pnoise raw data file. Does anyone know how to address this issue? Thank you for your help!
