What is the best tool for RF design?

Hi, Sci-Electronics community! I am pleased to contact so experienced
enthusiasts and friendly people. I hope you will clarify me one question. I
have some aspiration about simulation of Radio and Electronics. I am sure
it may significantly reduce the time of design and lower the number of
errors. Using simulations we can have a look at the heart of a schematic.
But the most interesting advantage for me is that I can work for someone
far away from my home. Do you think it is possible? To explain the
situation, I wrote a little site www.simtronix.bravehost.com which probably
will interest someone who want to get free simulation of schematic and does
not want to buy software and study it.

So, is simulation the best tool for RF design?

Best Regards,



Robert Shell.
 
Seriously, a simulation tool can be no better than he who uses it.

Learners (aren't we all) are misled into believing a solution is the correct
one.

Rubbish in - rubbish out!

At best they can be educational. Learning on the job. Takes the tedium out
of it.

If it was, everyone who could afford a simulator could do it.

Especially helpful in visualizing things.

The thing that really elicited my comment was the bottom line, which
I went right to after skimming the drivel with all the misspellings.

He wants us to send him our schematics and he'll simulate them for
free.

Yeah. When pigs fly.

Ok, but on contrary, it's not because you have the best tools that you can
do the a good job.

Just give me the best surgery instruments, your body, and lets see what I
can do...

For simulators, every tool has its drawbacks... and its strengh. These can
be pretty useful (some times indispensable) if you're an *educated* user.


Thanks,
Fred.

I find simulation is a fantastic tool if used properly. Like everyone
else I made mistakes with simulation early on and probably still do
from time to time. But it *can* be a powerful aid to understanding
what goes on in a circuit and what effect changing parts around will
have in the rreal world. The biggest pratfall IMV is poor modelling,
which can get you into all sorts of problems.

To the contrary? That _was_ my point...

How about if you try it out in simulation first?

Not really. First you have to understand the core then you may
do some simulations to optimize some parameters.

Dear Reg Edwards, Active8, Fred Bartoli, Paul Burridge, Mike and all
responded my message!

It was my pleasure to read your opinions, thank you. The power of simulation
certainly depends on the user experience. And that was one reason for me to
offer free simulations at www.simtronix.bravehost.com I think if you work
for free you got an important reward : your experience. So pigs may stay on
the ground J, anyway I will be happy to help somebody if I could. The
problem is whether such work can be effective: if you work with your
schematic yourself you can simulate it again and again changing it and
improving step by step. If somebody do this work for you, you got the result
and .what if it doesn't satisfy you? May be optimizing schematic for certain
goals would be the answer?



Best Regards



Robert Shell.

If you are really interested in this thing:

90% of the people won't send your their projects because of privacy reasons.

Get a few of those scientifical programs for Linux and start a free "shell
account" service where people can run those programs over SSH (secure
communication) or Telnet.

Maybe use some Java applets to do the calculations... oops, I despise Java
applets (and I also despise Flash stuff).
