Document Table of Contents Examine the Need for Logic Optimization Across Partitions

Partition boundaries prevent logic optimizations across partitions (except for some limited cross-boundary optimizations).

In some cases, especially if part of the design is complete or comes from another designer, the designer might not have followed these guidelines when the source code was created. These guidelines are not mandatory to implement an incremental compilation flow, but can improve the quality of results. If assigning a partition affects resource utilization or timing performance of a design block as compared to the flat design, it might be due to one of the issues described in the logic optimization across partitions guidelines below. Many of the examples suggest simple changes to your partition definitions or hierarchy to move the partition boundary to improve your results.

The following guidelines ensure that your design does not require logic optimization across partition boundaries:
