Electronics Forum / CAD / September 2005

I have gotten this error a number of times using the new OrCad version
10.5 (Actually, it is the rule rather than the exception).  Usually
after a few simulations of any given circuit (can be a very simple
circuit), this error takes place.  Generally, I must close everything,

Can someone please convert an Orcad .dsn schematic file to jpg or screen
save as a bmp file and email me at oparr@hotmail.com? The file is at
International Rectifier's web site below, click Schematics (.dsn) on the
page;

I try to install PSpice Schematics V.10.5 with Orcad 10.5, and get
error message "AlsSrVrVC6.dll not found" when the program is invoked.
Anyone knows why ?  Thanks.

Je dispose de schémas créés avec ORCAD3 (sous DOS).
Connaissez-vous un logiciel qui permettrait d'ouvrir et d'exploiter ces
schémas facilement ?
Merci d'avance. AC.

I'm currently drawing a little PCB with Altium's Design Explorer DXP
(7.2.85). After drawing the schematic I got it converted to a PCB.
Currently I'm doing the PCB layout.
I'm now desperately searching how to drag a group of components and wires.

I've spent a few hours over the last couple of days trying to design a
realistic and easy-to-handle simulation for break-before-make toggle
switches. But I imagine this is re-inventing the wheel, as there must
be well-established techniques. I'm using Circuitmaker, but I assume

Hspice "multijob" questions....
regards:
What does HSPICE "multijob" mechanism mean?
Does it mean someone can use "multijob" mechanism to simulate many

I am trying to design a simple microcontroller board based on Philips
LPC2106 chip. Got my hands on OrCAD, using Capture and trying to find
LPC2106 part with no luck. Am I looking in wrong place? What are my
options? Do I have to create it myself somehow?

i need to design a board that lies beyond the capability of the lit

4.13 please send me

I downloaded SwitcherCAD and set up a circuit without much
effort, but can't seem to get any simulation to work.  I'm
new to this program, but have used Electronics Workbench and
CircuitMaker, and of course signal generators and scopes.

Regards:
  What is the diffrences between pspice and Hspice????
  Thank you

Dear community,
can someone explain to me some misunderstandings. There is a differencial
pair in a PCB. Simulation returns: Impedance 65.5 ohm, differencial
impedance 98 ohm, common mode impedance 82 ohm..I wonder what is the

I have a circuit comprising one OP-77/AD op-amp that is basically a
Sallen-Key filter with some other resistors and capacitors around it.
All capacitors use a tolerance (10%) and all resistors use both a
tolerance (1%) and a tempco (100 ppm/C).

I'm using Protel99SE and have been apprroached by Altium with an upgrade
path to Protel 2004. HAs anyone got 2004 that could give a heads up on
how it compares to 99SE?

I'm using Protel99SE service pack 6 and wonder if anyone has a fix for some
of the problems I'm seeing. After doing a print setup and print preview,
the system gives me an error indicating that it could not read memory at a
certain location. I'm running this on a Pentium 4, 3GHz, ...
