And when that 1000 pin FPGA symbol you got from somewhere has several errors
in it, those 60 minutes you saved your self turns into a nightmare when you
get your PCB's back :) How do you know that symbol you just got from Joe
Schmo in an email attachment has ever been used or tested before?
I see this all of the time and after being burnt by it several times I now
make EVERY symbol and footprint that goes on my PCB's. I've not used
an
OrCad supplied symbol in years.
Sorry if it seems like I'm dumping on you, but I've been doing
schematic's
and PCB's for 20+ years and I'm just trying to help you out in the
long
run...

It's not that I (or others) don't know how to use these things,
it's just
that everyone is always under very tight time constraints. If you need to
take a day to create the physical parts in your CAD software then that's
one more day until you're complete. When you're working on tight
deadlines
and 10 hour days to meet unrealistic deadlines then that starts to make a
big difference. Add in the fact that (typically in my experience) every
extra hour spent in the original design phase planning and thinking is
worth 4 hours of debugging time. Rush the design, spend a lot more time
debugging. So saving a day by using libraries already made, which are
already tested and known to work, can save several days down the
line. Waste not, want not.
And it doesn't take a day to read a few responses :)

... and I've got 20 or so ICs in my design, 4 or 5 major ones, so if
someone had already made them then I could save myself 5 or 6 hours of work
... I'm particularly looking for the footprints, since those can be tricky
and need to be very precise.

I have to agree. By the time you typed your post and have read all of the
responses you could have made your own part. I've even done around 1000
pin
FPGA's in an hour or so using the cut and paste method...
Take the time and learn how to use Captures symbol editor, it won't be
wasted time.

Sorry for not helping answer, but it takes half an
hour to make 144 pin component in Capture or Layout.
Using Copy and Paste from the Datasheet.

Hey,
Sorry for the "me too" post, but I was also just about to post a
request
for this. Specifically for me the LPC214x part, and more in general if
anyone knows of any good libraries with commonly used components that
don't
seem to be included with OrCad.
Thanks everyone,

Hi,
I am interested in checking out some OrCAD libraries for LPC2000. Could
someone please help me out.
