I try now and run ok, thanks.
Thank you for helping to improve the documentation!
I must help in the way I can. :^)
(And, on the other hand, I have solving my own problems)
There are anyway to obtain a RMS wave output (with a control
structure, specific print sintaxis or anything)?
I don't understand. Isn't that what the RMS measure does?
Measure give me the RMS value of a signal, this isn't exactly what I want.
Something that next (for control structure):
.control
i=0
while i<=end_tran_time do
measure rms_wave = rms(probe="signal(output)" begin=i
+ end=time_step_a)
eval rms_vawe >> wave_file
i= i+ time_step
time_step_a = time_step_a + time_step
.end_control
ok ....
The "while" command is on the to-do list. Once it exists, you
will be able to do that.
I am still trying to figure out what you are trying to do ..
Ok (I hope that expression exits on english too), one image better that
a millar of words:
http://fie-conference.org/fie96/papers/219.pdf
Image at page 3 on top.
building a file .. "wave_file" ... which will contain a table
of the RMS values of the wave, in time intervals, over time.
Yes, the objectiv is print these rms values over time: a rms wave of a
signal.
The signal is a modulated waveform, and you want to look at the
envelope as a time domain signal?
I'm not sure here (language problem here). In the previous control
structure I try to attach to ecuation of:
http://en.wikipedia.org/wiki/RMS_value
but, I see that not the same in spanish Wikipedia:
http://es.wikipedia.org/wiki/Valor_eficaz
This calls for the real Verilog-AMS, behavioral modeling. It's
coming. With that, you could make a device that would do that.
Ok.
I have still hope to not write a octave or python function
for made this. Should be more easy write a rms wave plugin?
You could make a plugin. Look at the existing "measure"
plugins, particularly measure_rms.cc.
Meantime Verilog-AMS behavioral modeling is coming, I try to get a
plugin or anything to do this.

Thanks for all, sorry about language problems.
Salud y Revolución.
