}Positives
É2X improvement in performance and power
+Carefully designed macro cells
+Dynamic logic (e.g., self-resetting domino)
+High-speed flip-flops and latches
+Low-voltage design
}Negatives
−Increased design time (~36 months)
−Charge sharing problem with dynamic logic
−Aggressive two-sided timing assumptions
−Extensive analog verification pre and post-layout
−Still may have high electro-magnetic interference
−
}Full-custom versus semi-custom --
}Basic tradeoff between productivity (design-time) and quality
