We want to convert traxplot .txt ncdrill files to be used for a cnc
pcb drill
and was interected to know if anyone knew of any conversion software
that might be out there to convert .txt to .nc files.

When I activate the "Wire" mode, the mouse pointer disappears. I've
tried different screen resolutions and color depth, but that didn't
help. Any idea ? thank you.

I'm using Protel DXP for PCB design (fully manual routing), and I often need
to fill large areas with copper (grounding, high current paths, etc.). Is
there a way to tell the s/w to fill an *arbitrary* closed outline with
copper (other than the polygon plane tool)? What I usually do ...

I have been using simplorer lately for designing power electronic
circuits.  Is there anything else out there that can accuratly
simulate transformers, inductors etc?  I seem to remember that pure
spice based simulators had some issues with magnetic simulation.

I would like to invite you to visit my web site: http://www.oshonsoft.com/

Hi to all;
    Hi to all:
This is a question for PowerPCB users. What is the quickest way to add
fanout via's to a BGA decal. Also, how do you place a free via

I play with electronics as a hobby and am used to using Circuitmaker's
spice simulations with transistor-based applications, and I've etched
a few PCBs at home. The digital arena however is confusing.
Q1) Can digital parts be simulated? I have heard of the VHDL language

I have a custom library with 4 parts, each one has both a symbol and
package.  When I click the ADD button, that library is not on the
list.  I double checked and the green ball is not clicked.  When I
view libraries from the control panel, custom is there, but only

I've noticed that my protel 99SE ddb files seem to like to expand in size, a
simple design can end up being wrapped in a 10 MB ddb file. If I export the
files from the ddb file and recreate the ddb file by importing the files
into a fresh ddb the resultant file is small (as ...

The mmsim.ini file has my libraries under program files. However, the import
process doesn't recognize the space in program files and uses program
instead, so throwing out an error that it can't find my symbols. How can I
get around this problem apart from moving my library?

Being a new user of Eagle Cadsoft, I am very frustrated with the
quirks.  Can anyone tell me how to CUT (copy) a symbol in one library
and PASTE it in a different library to create a new device?  I opened
the LED.lbr selected the symbol for U57x32. I used the CUT command.  I

I'm (trying) using Orcad PCB 386 V4.42 on windows 2000. But, it
doesn't work. I have a BATCH file for configuring Orcad's environment
variables. When I try to run that Batch, screen is getting black.
Also, I try to set environment variables within windows's environment

I wanted details about the pricing and contents of the following book.
Macromodeling with SPICE,Connelly and Choi, Prentice-Hall 1992
I tried out pretice hall website but i cpuld not find any info there.
Is this book still available?Can i get it in india?

Does anyone know how to handle pins in a PSpice A/D circuit using
CD4000 series IC models.
My specific problem is with the CD4013 dual D type flip flop connected
as a divide by two circuit.  I am using + and - 5V supplies, specified
