dear forum members,
I would appreciate it if anyone could help me with the following problem. I am trying to export s-parameters, noise-parameters and some DC values from an amplifier design as function of a bias current sweep.. I managed to setup ADE Explorer/Assembler with the appropriate outputs and now can access the s-parameters per bias point, see script below.
Unfortunately, I only can do a single-frequency s-parameter measurement, which is annoying, but I could live with that:
import cadence.srrdata.*
import cadence.Query.*
adeInfo.loadResult('DataPoint',1) ; for starters, could add other datapoints in a loop
cadence.srrdata.aaSP(1,1,'result','sp-sp').x ; gives the bias current scalars
cadence.srrdata.aaSP(1,1,'result','sp-sp').y ; gives the complex numbers for s11, as function of bias current
More importantly, I so far have not been able to retrieve the noise scalars (NFmin, Gmin, Rn). The documentation I've seen focuses (RAK, User Guides) on transient measurements. Also, a cadence.srrdata.NG data access function is mentioned in the Matlab help file, that is supposed to give a "noise gain waveform", whatever that is, but cannot get anything out of that either. I've been struggling with this for the past two weeks, please help!
I am using Spectre 18.10.077, IC 61.7.722 and Matlab R2018b.
