3.1i Virtex-E Floorplanner - Secondary DLL does not appear in the Floorplanner


Keywords: 3.1i, 2.1i, Floorplanner, Virtex-E, secondary, DLL

Urgency: standard

General Description:
The Floorplanner does not show the secondary DLLs in VirtexE, so
there are only four DLLs visible. This is incorrect because VirtexE
has eight DLLs, four Primary and four Secondary.


For constraints purposes, the Floorplanner does not really
need to have the Secondary DLL since it is attached directly
to the Primary DLL. So, if you Floorplan the Primary, the
Secondary will automatically be placed next to it. Also, the
Secondary DLLs can be most commonly used in the 4X multiplication
configuration. For more information on other DLL configurations,
please see the following app note:
