14.7 PlanAhead - The PlanAhead tool stops inferring buffers after exiting Hierarchical Design Mode

Description

In a 14.6 or 14.7 PlanAhead Hierarchical Design Flow, if a partition is created and then subsequently removed, a message pops up asking the user if they would like to leave Hierarchical Design Mode. Regardless of whether yes or no is selected, the PlanAhead tool stops inferring buffers in subsequent Implementation runs.

Solution

This issue has been identified in PlanAhead 14.6 and 14.7.

To work around this issue, create a new project.

To avoid this issue, do not enter partition mode if a partition is not desired.
