M1.5 - Floorplanner does not recognize LOC attributes on some IOB components

Description

Keywords: M1.5, floorplan, LOC, IOB, ignore

Urgency: Standard

General Description:
When LOC constraints are assigned to IOB components that are not IBUFs, OBUFs or PADs, Floorplan ignores them. MAP and PAR view these constraints as valid, and place them in the correct IOB. However, Floorplan does not recognize these constraints and does not display the signals as being LOC-ed to the IOBs in the Floorplan window.

Solution

A work-around is to assign the LOC constraints to the PAD, IBUF, or OBUF.
