4.1i Floorplanner - RPM shifted up/down half a slice in Floorplanner

Description

Keywords: 3.1i, Floorplanner, slice, shift, up, down

Urgency: Standard

General Description:
I created several RPMs by putting RLOCs on the component labels with VHDL attributes. When I try to place the RPM in Floorplanner and save the Floorplanned design, MAP shifts the RPM up/down by half a slice.

If I perform an automatic place and route, it is placed correctly, but Floorplanner displays the RPM with the half-slice shift.

Solution

To work around this issue, highlight the RPM in the hierarchy window, then select Pattern --> Unbind. Then, drag the RPM components onto the floorplan and place them. Finally, with the RPM highlighted, select Pattern --> Bind.

This method will not affect the RPM structure and allows the RPM to be successfully placed in the floorplan.
