Three-phase chip planning-an improved top-down chip planning strategy

Schurmann, Altmeyer, Zimmermann
1992 IEEE/ACM International Conference on Computer-Aided Design  
This paper introduces an improved top-down chip planning method that reduces the effects of these deviations.  ...  The most important precondition for top-down chip planning is a good area estimation.  ...  These differences between estimation and final layout make an improved top-down chip planning method necessary. We developed such a new planning strategy which we call Three-Phase Chip Planning.  ...
