Short answer:
APD is primarily a single die, or multiple signal-die-stacks design tool. Granted, designers have been creating multiple die-stack designs for years in APD, but they have done so under the limitations of the layer stack editor to accurately represent and manage complex single and multiple stacks.
SiP Layout incorporates functions to:
-Manage Connectivity
Save days creating a system netlist using table driven connectivity manager for multi-die designs
-Manipulate Die Stacks
Save hours by automatically handling pad stack changes
Save hours by automatically handling multiple die stacks in the same design
-Perform 3D visualization and design rule checks
3D viewer integration with SiP saves hours over setup work required with complex die stacks in APD
-Assembly Rule Checks
Prevent package design respins using back-end design and assembly rules that ensure
manufacturing-ready designs (only available in SiP)

Bill
