Re: ADEXL and Montecarlo : 'global' PSF file creation
[quote user="Andrew Beckett"]Hi Michele, A quick answer because I'm tied up with meetings today so can't really focus on this (so it might be best to go to customer support).The PSF database at the top level should be empty, because it is populated based on what ran - it's actually a set of references to the lower level run ...

Re: ADEXL and Montecarlo : 'global' PSF file creation
Hi Andrew, thanks for your super-prompt reply :) However, I was not clear enough: in my outputs setup, there are signals and expression which are 'working'. For these, I can see the mean/sigma current values and even plot the partial results (histogram) if I want. However, next to those, I also have expressions which do ...

ADEXL and Montecarlo : 'global' PSF file creation
Hi all, I have a *very long* MC run which is taking far more than expected. It simulated some 1000 points already and I would like to examine the results. Unfortunately (for a reason that escapes me) the most important parameter is an expression working for normal sweeps but not for MC. Therefore I cannot see what I would like right now. I ...

Re: Defining Noise in VDC by using noise/freq pairs
Ok Andrew, there it is. Very basic...But I think it is usable to build 'noise profiles' on the fly. It is fixed @10 points per decade but it is easy to change that. One possible improvement would be to allow for kneepoints not on the raster...But that involves some check :) Hope this is of some use, Michele

Re: Defining Noise in VDC by using noise/freq pairs
Hi Andrew, d'oh! It totally escaped me...In the mean time, I had to come up with some 'log/log plot generator' for my sake , based on Excel. It is super basic but if anyone is interested and it is allowed, I could attach it here. This is how it looks like: Kind Regards, Michele

Defining Noise in VDC by using noise/freq pairs
Hi All, if I set: number of noise/freq pairs : 3 Freq1 : 1k Noise1 : 1e-12 Freq2 : 100k Noise2 : 1e-18 Freq3 : 1M Noise3 : 1e-24 I would expect, similarly to what happens with pwl sources in time domain, to get a piecewise linear frequency characteristic. This is however what I ...

Re: Integration of bsource in schematic views
Hi Mark, thanks for the tip! I am not a CAD engineer so in the mean time I shifted my focus on some other stuff, given that the subckt approach was doing what intended. I will surely try your suggestion as soon as I have some space left, it looks interesting and I shall definitely deepen my understanding of the Cadence/Virtuoso ...

Re: Need USEFUL, PRACTICAL, and FEASIBLE procedures to design, simulate, and layout "REAL RF Transformers" using Spectre RF
Ok Andrew, thanks for your feedback. Let's see what comes from the OP now :) Michele

Re: Need USEFUL, PRACTICAL, and FEASIBLE procedures to design, simulate, and layout "REAL RF Transformers" using Spectre RF
Hey there, a couple of comments : 1 - I am not sure this topic fits well in this type of forum, being more design oriented and less tool oriented. Do you know www.edaboard.com? There's plenty of great design advice there, if you want to try it. 2 - On a general note, being myself an industry designer, I know that there is a long path to go ...

Re: Need USEFUL, PRACTICAL, and FEASIBLE procedures to design, simulate, and layout "REAL RF Transformers" using Spectre RF
Maybe not the answer you were looking for, but I guess you can't work around an EM simulator for the task. In a Company I worked for, they could start a design from a Matlab script, where they implemented some basic equations. But of course that was only a first step. Then you have to sim your structure electromagnetically, and after that you ...
