2.5.2.9. Include All Tri-State and Enable Logic in the Same Partition
The figure shows a design with tri-state output signals that feed a device bidirectional I/O pin (assuming that the input connection feeds elsewhere in the design and is not shown in the figure). In the left diagram below, the tri-state output signals appear as the outputs of two separate partitions. In this case, the Quartus® Prime software cannot implement the specified logic and maintain incremental functionality. In the right diagram, partitions A and B are merged to group the logic from the two blocks. With this single partition, the Quartus® Prime software can merge the two tri-state output signals and implement them in the tri-state logic available in the device I/O element.
