Anybody found Amazon's "So You Like To..." Guide useful?
Recently, I visited the website to search for some references, and I
found quite a few informative and interesting reader-supported guides.
Here are my favorites:

  Dear Reader!
As an example I try to perform a parameter sweep
of a simple voltage divider (R1 and R2 in series to a 10V DC voltage).
One of the resistors  shall be the parameter.  The divided voltage I

I am accustomed to using two digits in my bus numbering so that signal
names sort correctly.  That means I would name a bus BUS[15:00] instead
of BUS[15:0] so that the lower signals would be BUS00, BUS01...  I am
getting errors in Orcad about wires with only one connection.  Is this

I am trying to evaluate some of the lower-end PCB design packages to
select
one for use in my workplace. So far, Altium is looking pretty good.

I'm trying to edit a schematic using PADS Logic. It won't let me edit
a net name. If a name is something like $$$1234, and I click it and
try to edit the net to anything else, the net name in the dialog box
is grey and can't be changed. I can add an offpage connector, then a

I have got a problem when i first use HFSS. During analyzing, a error
code generated said:    "Initial mesh process mesh3D: Error while
opening or writing the mesh files". I know it is so trivial,  but i
just cant get over it.

I completed a schematic and layout in Orcad 9.2.3.  Then I needed  to
change the type of some connectors in the schematic, from 5 to 3 pin,
as well as re-route some traces in the schematic.
I created a new netlist from the schematic.

I need to link up/attach two pcb's together.
Whats the best connector for the bus lines? I need at least 40 pins.
Someone suggested I use the same connector used on an IDE harddrive
and on PC motherboards.

before I got Orcad9.0 running under WINNT 4.0, no problems.
But, now I use WINXP and whenever I try to install Orcad9,
via the splash menu, I get following error:
SPlash MFC apllication has encountered a problem ...

My 17th patent, issued last Tuesday, is now posted on my website
(spread spectrum for WiFi).

I thought this would be simple, but how do I plot transimpedence gain
in PSpice. I have OrCAD 10.5 full suite, so PSpice is part of
CaptureCIS. Google was of no help.
Thanks,

There seem to be several models for the 2sk170 out there that have fairly
different parameters. Is there one that we know is good?

Anyone else have problems with Ltspice crashing in wine?
I have a amd64 4800+ x2 machine with Redhat Rhel ws4 loaded on it.  I
loaded  wine-0.9.2-1centos4winehq.i686.rpm which is supposed to be
compatible:

The Hope and Atlanta are two  open source ATPG programs.
In my study,I need to use the two programs,but I don't know where I can
get the two programs,so I come here for help.
If you know where I can get the two programs ,it's appreciate for you
