320pin BGA Pin Layout suggestions

OrCAD was very unstable until Windows Version 9.x. 7.x was horrible in so many ways. It still has issues with shorts when you move parts, net renaming and attributes but is sorta usable. Unfortunately it is what many engineers learn so I am forced to often use it since my clients use it. I do most of my layout work with PADS PCB. I prefer to use PADS Logic for the front end but will use OrCAD if they request. I charge extra for OrCAD because of the issues.

PADS is my favorite, too. The on the fly autorip-up for rerouted traces is glaringly absent in other packages. I liked Veribest, and some of those features are now in PADS since they were "absorbed".

I still get LOTS of Eagle garbage. Hate that program. And just had in a WinQCad job of all dang things! Can't believe people choose to use that crud.

Sure. I've even done pre-compliance testing (set up the lab).

Your word isn't worth much. You pretend to be the OP too.

You're being stupid. Another self-important nut heard from.

Joe, you still have to tell us what chip it is and how many of the pins you are actually using, that is important detail and determines how you will route your chip.

HIi Dave,

It's an NXP LPC3180

Data sheet - in the back section it has the pin outs

Regards Joe

That only answers half of the question - which ones do you plan to actually _use_?

And please don't top-post:

Thanks, Rich
