Hierarchical front-end physical design solution drives modified hand-off

A design methodology for the implementation of multimillion gate system-on-chip designs is described The new methodology is based on the creation of a physical prototype early in the back-end design process. The prototype is generated in a fraction of the time required to complete the traditional back-end flow but still maintains very high correlation with the final design. The physical prototype becomes the ´hub´ where many design implementation decisions can be optimized by leveraging the short iteration times. Hierarchical design methodologies benefit from the prototyping stage by enabling a more optimal partitioning. The physical prototype also alters the nature of the hand-off model between front-end and back-end designers. The netlist can now be quickly validated using the prototype: the physical reality is being injected early in the design process resulting in fewer iterations between front-end and back-end.
