3.1i MODULAR PAR: WARNING:Place:1701 - List constraints, non-rectangular range constraints
描述
Keywords: Modular, design, area, group
Urgency: Hot
General Description: Placer is not processing the constraints correctly. It gives the following warning message:
WARNING:Place:1701 - List constraints, non-rectangular range constraints, or non-contiguous range constraints have been applied to objects in this design. Xilinx recommends that you convert such constraints into contiguous rectangular range constraints.
It was verified that the floorplanner was creating valid area range constraints. This will happen for all modular design cases where SelectIOs are used
解决方案
This problem will be fixed in the first quarterly update to 3.1i which is currently scheduled for August, 2000.
