Hi!
I have a simulation with long time constant blocks that I typically need to let settle for about 1-2 us before doing any useful measurements, including periodic noise. Some of these measurements are performed with "tran" analysis, while the rest is evaluated using "pss/pnoise"
Since I would like to avoid running similar transient analysis twice (1x tran, 1x pss/tstab) for both measurements, I think I could do the transient measurement at the end of the tstab period, and ideally, be able to save only the last portion of the transient in tstab, saving additional simulation time and disk space.
Currently my solution uses tran analysis with outputstart set to a predefined value to only save the required waveform portion. But I haven't found this option in PSS/tstab.
Could you provide an example how to set this parameter in tstab?
Thanks,
Erick
