In phrase of LTC Spice

[Roy McCammon]

Well, I've downloaded it several times, but I actually used it
for the first time last week.

It worked without bugs, and was sufficiently intuitive
for me to get it working without any help. That's
unusual for me; I usually get overwhelmed with the
possibilities. Throw in my dyslexia which makes
icons very difficult for me to decipher and its a
real accomplishment.

And, since its free, it makes a good medium for
exchange of circuits.

Good job, and Thanks.

Are you serious about dyslexia or kidding?
I don't think I'm dyslexic, but I find most Icons completely counter -
intuitive with a few exceptions; I get the picture of the printer for
example.

I also am baffled by the way phone companies select headings for product
and service companies in the yellow pages. Maybe I ma dyslexic

So, you place the cursor over the icon, and a text box pops up to
explain what it is. Sometimes it does, sometimes it takes 10 seconds,
and sometimes it never shows up. All in the same program.

Cool, I've only just managed to notice that you said In phrase rather
than In praise, I just spelt rahter as rather NAAAAAAAA the other way
around. I'm not sure that's a real word, rather that is. If I look at it
then it seems stupid..... Oh shit now I'm having problems with
problems... I mean stupid, I wasn't having problems with problems. Now I
hit sobriety and it all makes someword sense. I'm embarrased.

Sorry, it is indeed a nice program.

make that Praise

told you I was dyslexic

serious.

In my case, something's missing in the visual processing
that makes a lot of things look the same (letters, faces,
icons).

It is good stuff isn't it. The interface is quite
intuitive......feels to have been designed by engineers
for engineers.

On the strength of it I went out and bought LT's
LinearView CD ROM, in order to get a full set of
their data sheets. Less luck with that though.
It installs ok, but the damned thing won't start
up until it is allowed to go on the internet, and
the machine it is on is not connected to the net.
There must be a workaround, but so far that CD
ROM has been a total waste of money.

I got my for free......
But one of the worst data CD's I payed for was the UK's maplin catalog

Serious error.
All shortcuts have disappeared.
Screen. Mind. Both are blank.

My daughter is dyslexic, so I have some interest in the area.
I've seen some research that suggests you may be right about
the "visual processing". There were some promising results
by simply changing the colour of the text being read, although
the subjects had no apparent colour blindness.

I'm not dyslexic, but I also find many icons impossible to
decipher.

My daughter is dyslexic also. We tried the colored overlays
and there was a temparary improvement. I figure that she was
trying harder because we were watching.

Also, everyone has good days and bad days. You need to gather a lot of
data points to see if an effect is real.

If she's into science projects, you can make this a large experiment.

Have her read holding the paper in her right hand and then switch to left.
Try green filters, brighter lights, music in the background, stuff, stuff
and more stuff. You plot the data in lots of different way etc.

You'll get lots of practice with making pie charts etc and she'll get lot
of practice reading. If you design the experiment right, the two of you
can get published like the girl that did the project on healing touch.

that would be fun, but that was a long time ago.

I believe it was pretty much designed by one guy at Linear. There was a
debate a year? or so ago over on the simulator newsgroup about whether or
not that one guy could have possibly done it himself (having taken a class
in building circuit simluators and having met the guy who built the version
of SPICE used in a well-known company for decades, I'm certain he could have
and did) given its high quality relative to the commercial simulators
costing thousands of dollars. (The ironic part is that many commercial
simulators got their start by simply wrapping Berkeley SPICE is a nice GUI
and charging for the results!)

For those that expect Windows standards, this is debatable. In my
personal opinion, its very non-intuitive. You can't even just drag a
part in one go.

feels to have been designed by engineers

Ahmmm...

Speaking from a *user* point of view, and having actually noted many
comments in the NG, and although the LT GUI is indeed useable, it is
certainly not the best in user friendliness.

Have you actually tried the SS GUI?

I believe it was pretty much designed by one guy at Linear.

There is some question on this to my mind. Sure, the Spice engine
itself, is a very decent piece of work, and the very significant
improvements to the basic spice architecture was, arguable, one dude.
However, the schematic format is identical to another companies
(Cohesion) suggesting that the GUI was originally developed externally
and licensed.

There
was a debate a year? or so ago over on the simulator newsgroup about
whether or not that one guy could have possibly done it himself
(having taken a class in building circuit simluators and having met
the guy who built the version of SPICE used in a well-known company
for decades, I'm certain he could have and did) given its high
quality relative to the commercial simulators costing thousands of
dollars.

Having access to the knowledge that many others already developed allows
one to have a good head start. If one was writing the *first* simulator
in ones bedroom, the situation would be very much different. So, yes,
there is no reason why a single individual couldn't write a simulator
from scratch, after the fact. However, for example, developing a good
BSim3 model requires PhD level physics. Implementing such equations is
much, much easier.

For reference, I actually wrote from scratch, a complex gaussian
elimination, with partial pivoting program on the Adam Computer around
1985, but this was done with the knowledge that I obtained in a
numerical analysis course I did, I think in 2nd year at uni. Again,
implementing what you already know is usually a no-brainer.

(The ironic part is that many commercial simulators got
their start by simply wrapping Berkeley SPICE is a nice GUI and
charging for the results!)

Are you suggesting that this has no value? SS is over 100k+ lines for
the GUI and took 4 years. Should this be given away or free? One could
use the same argument and be derogatory to all board level design, as
board design simply plugs in already designed i.c.s.

*All* products use other exiting products. Its just the way it is. The
daft thing is re-inventing things that already exist.

We have a family of dyslexics inheriting from both sides of the faily.
Dyslexia is a symptom with many causes,
I observe a distribution of mental processing power which is at the
extreme end fo the normal distributipon.
One member of the family hase gifted visula intelligence but very little
short term memory.
Note; I leave the above as I typed it to show my problems!

The Hawthorn effect has nothing to do with dyslexia, but everythng to
do with variations in preformance due to social interactions.

Dyslexia is an interesting subject in itself - I had a dyslexic style
problem when I was first learning to read, in that I confused "saw"
and "was", but my parents managed to straighten it out very quickly.

Dyslexic engineers are not uncommon - one of the brightest engineers
of my acquaintance couldn't tell the difference between "their",
"they're" and "there" and used all three spellings in each of the
three possible situations. This and similar phoneticly sound
substitutions made reading his reports more difficult than it might
have been.
