I happened to come across an electronic copy of Microsim's old (1997!)
application book... its available for download at
http://www.it.uom.gr/project/digital/appnts.pdf, and much of what's in it is
applicable to any SPICE-type simulator.  It's really quite good...

As my previous thread in this group became more or less off topic after
a while, I start this new one with a related but different question:
I now can perform pole zero analysis with ngspice (using the command
line mode).

Just received an invitation to a seminar about Cypress PSoC. It seems
they'll introduce PSoC Express, for the most part. I checked out the
tutorial on Cypress' site and at first glance it looks quite similar to
the VisualState package IAR offers for the MPS430 and others. I ...

I'm trying to model an inductor which varies inductance according to
the terminal potential (don't ask why!).
The inducance is high when the terminals are close to 0V,
and reduces according to 1/(V1+V2)^3. (where V1 and V2

Hi, I want to plot layout from Protel 99 SE directly on film, with my
HP7475A.
Windows drivers arre not good because they are clogging pen very
quickly (their output is quite chaotic with many penups and downs which

i am working for a whistling keyring project as my final year project
(is about agadget, i.e you lost your keys in your office or your room
you just make claps and it start ringing)
and i need a circuit diagram of it and its working principles;

I'm trying to perform pole zero analysis with spice3f.
This is the circuit file:

Hi! Where can I download a copy of PSPICE?
Thanks.

Anyone who is interrested to make there own power mosfet model for
spice can now easily do this with a tool i made.
It's a windows application and can be found on the yahoo groups
LTspice.

I want to create a Doomsday Device to terrorize the world.
What software do you recommend to design such a powerful WMD?

In the PCB package, I can't execute edit/select/holesize to select various
hole sizes so I can globally change them - i.e. 28 thou vias to 32thou vias.
I can do this on my win 98 machine.
I have wiped my client on my XP machine and cloned the 98 system onto my XP

    is there someone with experience on creating
SMD library components (layout and pcb design)
for Eagle Cad?
I need to build the ST7540 (ST microelectronics)

What is the difference between warm reset & cold reset (OMAP 5912) ?
Thx in advans,

Has anyone used anything other than the provided schematic entry for
LTSpice?
What I have in mind is using my venerable MicroSim Schematics as a
frontend for LTSpice.
