CONTENTS OF PCB_Packages.zip - [updated 20-JUL-2009]

- Allegro Folder
Allegro folder contains subfolder for each iCE package (CS63, CC72, CB132, CB196, CB284, VQ100) type. 
Each of these subfolders contain 
 (a)  .brd Allegro board file (breakout example for the package)
 (b) *_lib.zip file which contains the footprint library (Allegro) for the respective package.

The CB196 has two sub-folders - one showing a 4 layer breakout (that uses 1:1 (pad:Solder mask size) 
solder mask and another showing a 6 layer (using NSMD (Solder mask > pad dia size) approach) breakout. 

The CB284 has two sub-folders - one showing simplified layout but with fewer PIO pins and another
using tighter design rules that connects all available PIO pins.

This contains the Orcad schematic library for the following iCE parts:

iCE65L02 in CB132
