May i know which is the best tutorial for a begginer like me to enter
into PCB designing...
U experts please feel free to send all about the tensions, probs,
enjoyments, thrills and tutorials to me. Listening for U gurussss

LTspice Question:
I have a client using LTspice.
What is the best way for him to import a design from PSpice?
Would it work if I make my schematic into a SUBCKT that includes the

How does one specify "board size" in KiCad ..?
When I try to "Autoplace All Modules" all I get is:
"No edge PCB, Unknown board size!"
I just tested with a simple design.

Is there a binary for Spice 3f5 somewhere, that I can download, that is
compiled for windows.

In a Gerber file if there are no parameter codes RS274D is a block delimiter
required before the first function code? In a Gerber file that contains
parameter codes if function codes appear before the first parameter code eg.
G04, is a block delimiter required before the first ...

Is there any way to stop OrCAD Capture from changing the registry?
It seems convinced that I should open all of my HDL files with a
schematic capture program.  I think a text editor, simulator, or
synthesizer would be a better choice, but no, it re-assigns all those

I use Lt spice.
I want to design an inputfilter for a circuit of which I have:
- the transfer function (table: frequency, transfer, phase)
- the input impedance as function of frequency (table: frequency, transfer,

How it works is a long lecture and discussion in detail.  Since, I've
already started the discussion on another BBS and will not keep any
secrets or hide any schematics, I'm callenging all of you and the
pros.  This over Unity Device Really will work.  Join the discussion.

Where can EEs get "practical" classes to be better custom-ic designers?
If graduating electrical engineers wish to be considered proficient analog,
mixed-signal, or RF designers using commercial tools, what are their
options today?

I was going to ask in alt.cad but there's so much garbage there......
I have plans (66"x 36" ) that I want to increase by 2:1 and get a print. It
would be OK in 4 sheets.
Can anyone tell me if this can be done, and if so how and where?

just a quick question, maybe a little bit offtopic (sorry):
If a diode current is 15 microAmperes (forward), what is the voltage?
I need an answer as close to  'real life' as possible.
Its a silicone diode, 1N4148 or similar

I asked for a quote for OrCad from our local agent. Together with the
quote, they sent a letter from Cadence in which they stated that
OrCAD PCB Layout will only be sold up to the middle of this year.
After this it will not be available anymore.

I'm a new user of Eagle, and I've only recently gotten into
electronics.
I hope this is the right group for this post, if not... could someone
tell me which is best?

i made a schematic in orcad but i did't get how to simulate in pspice
any one can help me how to do this simulation,if any documents is
there plz send to me .

I have a very small board that I would like to model for thermal
analysis.  I am pretty confident that I can get by with a first order
analysis since I only want to know if I have a prayer of a chance of
dissipating the heat from this board, rather than a detailed analysis
