Description

I am trying to implement a Zynq based design in PlanAhead. 

During implementation the following critical warnings are displayed:

[Constraints 18-5] Cannot loc instance 'processing_system7_0_PS_PORB_pin_IBUF' at site B5, Site location is not valid ["/test1/test1.srcs/sources_1/edk/system/implementation/system_processing_system7_0_wrapper.ncf":154]
[Constraints 18-5] Cannot loc instance 'processing_system7_0_PS_SRSTB_pin_IBUF' at site C9, Site location is not valid ["/test1/test1.srcs/sources_1/edk/system/implementation/system_processing_system7_0_wrapper.ncf":155]
[Constraints 18-5] Cannot loc instance 'processing_system7_0_PS_CLK_pin_IBUF' at site F7, Site location is not valid ["/test1/test1.srcs/sources_1/edk/system/implementation/system_processing_system7_0_wrapper.ncf":156]

Is this a known issue?
