126.96.36.199. Turning On Supported Cross-Boundary Optimizations
You can turn on the cross-boundary optimizations for your design partitions on the Advanced tab of the Design Partition Properties dialog box. Once you change the optimization settings, the Intel® Quartus® Prime software recompiles your partition from source automatically. Cross-boundary optimizations include the following: propagate constants, propagate inversions on partition inputs, merge inputs fed by a common source, merge electrically equivalent bidirectional pins, absorb internal paths, and remove logic connected to dangling outputs.
Cross-boundary optimizations are implemented top-down from the parent partition into the child partition, but not vice-versa. The cross-boundary optimization feature cannot be used with partitions with multiple personas (partial reconfiguration partitions).
Although more partitions allow for a greater reduction in compilation time, consider limiting the number of partitions to prevent degradation in the quality of results. Creating good design partitions and good floorplan location assignments helps to improve the design resource utilization and timing performance results for cross-partition paths.
