Synopsys ICC v/s Magma Talus is the debate going on in the physical design circles for 45nm and lower technologies.

ICC has a good router but lack floorplanning capibilities. If Talus has is better than BlastFusion is terms of routing and floorplanning it has a edge over ICC. But is Talus out of its teething problems of new tools ? Or is Synopsys upgrading its ICC capibilities, we have to wait and watch.
Patience is wearing thin and the biggest bottlenecks in technology shrinkage seems to be EDA capabilities. Is there a new tool on the horizon Cadence long timer Encounter maybe ...
