awd = wavescan??

Dear all,
Is awd just the same thing as wavescan? They have a little different
GUI, but they all contain a reulst browser, a calculator and a
waveform window (or called graph display in wavescan package)?
I like the wavescan better, but seems the calculator in awd is more
powerful. Andrew or other people, could you comment on this? Is one of
them going to be discontinued? Thanks much!
Best regards,
Jay
 
Jay,

wavescan was introduced in IC50, and is currently usable standalone - not
through the analog design environment.

It does have a number of features not present in awd. For example,
the table output - which you can transpose, manipulate columns etc. Useful for
looking at waveforms in tabular form, and also for looking at operating point
information. Also the variety of markers and cursors and labels is much
stronger.

The whole look and feel is more modern of course, and also it can read both psf
and sst2 formats - and is quicker (more noticeable for large files) to load the
results. An example of the performance - I've read a waveform with 20 million
points and done a windowed fft on a section of that waveform (with something
like 16 million points in the fft - whatever the power of 2 close to that is),
and then plotted the results. The whole operation was between 2 and 3 minutes.
With awd I had to change the results out of AMS Designer (which is where the
data came from) to be psf or do some complex conversion outside, and then
awd took something like 45 minutes, and then ran out of memory...

The calculator is pretty similar in its capabilities (at least in IC5033), and
has a number of functions which awd doesn't have. The calculator language is
spectreMDL, actually.

Now, in IC5141 (out in June), wavescan will be available within the Analog
Design Environment - initially as an option (Setup->Waveform tool). When you
choose wavescan, all plotting from ADE will be done with wavescan, and you'll
get the wavescan calculator, etc. However, the calculator when run this way will
actually use SKILL syntax rather than spectreMDL syntax, in order to preserve
compatibility for people using OCEAN, and because all the Direct Plot form stuff
and so on is generating SKILL expressions.

So as you can guess, the idea is to replace awd with wavescan - awd is pretty
long in the tooth, and wavescan gives us a much more modern framework to allow
new things to be done more easily.

Sorry for the lengthy reply!

Regards,

Andrew.

Andrew, I (and other people) always can get nice advice/comment from
you. Thank you!
BTW, although it's fun to learn new stuff, I would really prefer to
staying with a minimum amount of CAD tools, which are sufficient in
terms of flexibility as well as compatibility. After all, tools are
just "tools". So do you think Analog Artist/OCEAN (which supports many
flavors of simulators) + wavescan will be sufficient for all
analog/mixed signal designs? Don't want to go through SpectreMDL just
for using the calculator...
Best regards,
Jay
p.s.: Analog Artist (Analog Design Enviroment) is just an integrated
version of OCEAN, right?

p.s.: Doesn OCEAN use SKILL syntax? Thanks.

I am not that impressed with wavescan. It seems to be just awd in
fancier clothing. I like the Agilent data display tool. One can
place plots, tables, and expressions anywhere on the screen just like
mathCAD.

Hi Jay,

I think that using Artist/OCEAN is likely to be sufficient for most things,
although there are some nice features in MDL which may be worth being aware of
even if you don't use them initially.

OCEAN is really a procedural interface to the same capabilities than a simulator
integrated into ADE gives you (it's not the other way around, since ADE preceded
OCEAN).

OCEAN is not a separate language from SKILL. SKILL is the language, and OCEAN is
actually a set of SKILL functions, an API (Application Programming Interface) to
allow you to run analog simulations. The syntax is all SKILL, but the
documentation is such that you don't need to know much about SKILL to use OCEAN,
although you can do more powerful things the more you know!

Regards,

Andrew.
