In the LTspice component attribute editing dialog box there is a section
at the bottom saying:
Simulation Results
  Peak Current      [         ]

I notice that even when X/Y offset is set to 0/0 in the CAM Processor
there seems to be an arbitrary offset in the file X/Y coordinates when
compared to coordinates in the editor. It also seems to vary from
board to board. For example, a drill placed at 0,0 in the editor

Hello, everyone,
  I am doing some simulation of VCO (4 stage differential) in spice3.
When I do the .tran analysis, the time interval of the output is not
uniformly distributed. It is not the time step I gave in the command:

Does anyone here have  (or know of) a software package to convert
EAGLE 4.1 net lists into other industry standards?  I am particularly
interested in turning out EDIF and PADS 2k lists from my already-existing
EAGLE schematics.

I'm looking for a spice model of a piezo actuator.

Thx.

Wondering if anyone is proficient in Protel99Se who can tell me how to find
the length of a routed net?
Thanks much,
Mark

Why is it that the manufacturers' footprints for SM devices nearly always
give the dimensions between the edges of the pads? I thought it was standard
engineering practice to give the dimensions between centres, which is what
is required by the PCB package I use, so I have to do ...

I want to design an amplifier with  voltage gain 0.5, which can be
used in a pipelined digital to analog converter..
I can do an inverting amplifer.. common drain type mos amplifier..(am
i on the right path?)

Hi people.
Just curious if someone here uses the B2 SPICE circuit simulator? Is it good?

I'm looking for a Spice model for a Loudspeaker, BUT I need CONE
DISPLACEMENT as the output.
Thanks!

I am discontinuing PC Logic.  The PCB layout and schematic capture will no
longer be available.  Thank you all for your interest and support over the last
11 years,

Anyone have experience importing EDIF into Composer/Virtuoso?
What I'm trying to accomplish is converting OrCAD Capture schematics
into Composer/Virtuoso schematics.
Thanks!

As a designer of a PCB / Schematic Design tool I am continually asked
for more libraries. However, except for a few exceptions I am finding
it exceedingly difficult for anyone to give me up there "list" of most
common or useful components.

I am looking around for Gerber Viewers. Of course freeware would be best, very
cheapware  might be considered.
I just want to view Gerber files. Don't need to edit or save them or anything
special. I presently use Viewmate, which is pretty nice, but is more of a full
