[PCB_FORUM] Re: Importing orCAD schematics

Patrick,



Thanks for the response.  I found out that the schematics are orCAD v10, but
I doubt that they are pointing to my Allegro symbols.

 

So, if this is the case, I have to create a device file for each different
part (i.e. 0603, sot23, tsop24 etc.), right?

 

I did a library dump on a design I'm working on now, and here is the device
file for a 60 pin BGA:

 

 

(DEVICE FILE: DDR2DRAMX8_60-60)

 

PACKAGE BGA60_8X12MM_0P8MM

CLASS IC

PINCOUNT 60

PACKAGEPROP PART_NAME DDR2DRAMX8

 

END

 

 

Do I really need all of this in the device files (obviously a 0603 device
file would be much simpler!), or are there just a few basic things needed?

Could I do a library dump on a very large Concept -> Allegro design that
uses many different symbols, then use the device files for the orCAD design?

Sounds like it could be quite a job creating all of the device files for a
pretty good size design!!

 

Thank for the help Patrick!

If your customer has v10 or higher, and has your footprint names in the
schematic, then you should have him put out the special allegro netlist set.
Otherwise, there is a fair amount of 3rd party setup you have to do,
including creation of simple device files.

Hey guys,

 

Sorry if this has been covered lately.

 

I have been asked to do a small design for Marketing (!?!), and they, for
some reason, use orCAD for schematic capture.  It has been years since I
imported anything but Concept HDL.

 

So in the Import Logic window, Other tab, do you just point to the orCAD
netlist (?) in the "Import netlist:" field?  Anything else or is just that
simple?

 

Thanks for any help!
