10.1 Constraint - The design seems to be flattened even if KEEP_HIERARCHY is set to TRUE

Description

A design having an XPS design as a submodule appears to be flattened even if the KEEP_HIERARCHY is set to true. This is making post-layout simulation debug very challenging.

Solution

Along with keeping the KEEP_HIERARCHY set to yes, "Preserve Hierarchy on Submodule" in Translate Properties must be set. This shows the Hierarchy during the post layout simulation.
