11.1 PlanAhead - When I launch PlanAhead for Floorplanning from Project Navigator, no hierarchy is present.

描述

I do not see hierarchy within the netlist window when I launch PlanAhead from Project Navigator Post-Synthesis. Why?

解决方案

By default, XST has the "Keep Hierarchy" attribute (-keep_hierarchy switch) set to No. To set hierarchy for floorplanning, change this to Yes or Soft by right clicking on "Synthesize - XST" and selecting "Process Properties".
