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 did ask about this on the EAGLE support news group, but nobody
there knew of any s/w to do this. Net list conversion doesn't seem to
be too difficult, once you know all about the formats, and I can't be
the only one interested in this!!

FWIW, the Pulsonix software I use can import Eagle schematics and PCB
designs.

Thanks Spehro
Yes i had done that with no results!!(holes all VERY close together)
what i Have discovered is that the protel nc drill file appears to
give its position of the pads in multiple's or fractions of 0.1" from
the origin so a pad at X 1.1" would be X011. So when it was imported
into kcam it became X000.011, looks like i need to find a multiply by
1000 to get it on the right coord's this would acount for the
previously thought no results. we will get there
Cheers
Dave

The coordinates in NC drill files have a fixed decimal place, and
normally omit trailing zeros. Usually the format is specified as
"2.3", meaning two digits before the assumed decimal place, and three
after (if there are no trailing zeros.)

Your coordinate of "X011" really means "X 01.100".

(just to add confusion, Gerber photoplot files usually omit leading
zeros!)

The merge command has the drawback that all nodes with the same name

Panel up? Ask the fab house.

Hi think about this. If you wanted to do an eco on your circuit
how would the cad system know which r1, c5 u3 etc that you
wished to change, since you now have 100 or more instances of each
unique part. ????? Even if it where possible to do what you ask,
why would you want to do it like this. There is a better way.

The task you ask is typically performed on the Gerber Files generated
from your cad data.Unlike cad data Gerber Files contain no electrical
information about the design. I.E no net info or pin info etc. They
are for all intentional purposes nothing more than a graphic
representation of your original cad data.

When you get multiple boards made, the board house typically use
panels of fr4 pcb material. They generate a composite plot of your
design in such a way as to get the best yield from a panel size.

Hope the above info is helpful.

Best Regards...Paul Hesse.

Hi again,

Thank you all.

The task to perform is to layout a burn in board for dynamic life test
of microelectronic circuits. Each cell has the burn in socket and R's
and C's.

Each cell must be supplied by different voltages and GND.

A duplication with GERBER would not connect these.

After a while, an application note on the Cadence site was discovered.

Their idea was basically:
- back annotate layout to Capture(schematic editor).
Capture holds the layout info in a spread sheet(COMPLOC).
- Duplicate the cell in Capture.
- Within the spread sheet, copy COMPLOC cells data
- change the COMPGROUP number for the cells components.
- ECO the schematic back into layout
- select the new cell by COMPGROUP number
- place the new cell to an appropriate board location.
Relative component locations are kept.

Best regards,

Dieter Tank, www.testhaus.com

Black background is probably good for PCB work, but I absolutely
despise colored schematics... schematics should be black lines on a
white background ;-)

I dunno... I sorta have a fondness for dark blue lines on light blue,
especially if the light blue is kinda motley and smells like ammonia.

I have complete analogue mosefet versions of jk and dtype models in my

these models in psice. There were created by drawing the real circuit

I think you have the cart before the horse.


Interview the candidates first. Then tell them how much money
you are willing to spend to buy them *their* choice of software.
Software is very much a personal item. You wouldn't buy a supply of

Stuff like that only happens in a Dilbert comic strip. Right?

Mathias

I'm sorry I can't help you with your enquiry but I do want to give you some
encouragement! I am a long time user of Orcad SDT 3.22 and would love to use
it a higher screen resolutions than the 640x480 that I've had for 15 years
and the 800x600 that I got this week!

Is the schematic part of Orcad 386 the same as SDT 3? and do they use the
same drivers?

Best wishes

Ian Phillips

Hello,

Does anyone know, if OrCAD has ever released a sample video driver source
code for their old OrCAD 386 series? I'm currently trying to write a new
video driver which fully complies to the VESA 1.2+ standard. Therefore
I've
"investigated" one of their drivers, called VESA1024.DRV. After many hours
of work, I already managed to fix a few bugs, so that the screen doesn't
get
distorted when moving the mouse or when a new menu pops up, but going any
further than that is very difficult. I wanted to rewrite the whole driver,
but due to lack of missing documentation I still don't fully understand
interaction between the driver and the program. ANY kind of help would be
appreciated! I already have a mixture of assembler and c source codes I'm
willing to share. They do compile and produce a working video driver.

With kind regards,
Matthias Hartl

Hello Ian,

Quote:

As far as I know they're completely different, although both user interfaces
look very much the same. SDT3 had to struggle with many limitations, because
it was a "real-mode" application. SDT 386+ runs in "protected mode" and
therefore has access to all built-in ram by means of a flat addressing mode.

Quote:
and do they use the same drivers?

I haven't yet disassembled a SDT3 driver, but I doubt they have the same
interface. It's certain, that the 386 series drivers have the same interface
as the ones for series IV, which still was real-mode. OrCAD 386 uses a
so-called real-mode interface handler in order to use the real-mode video
drivers from protected-mode. This is a bit of a hack, but it surely saved
them many man-hours of work rewriting drivers ...

With kind regards,
Matthias
