Version Found: v3.2
Version Resolved: 4.0 rev2 - all pblock size are increased so, all designs will fit with default constraint.
Other Known Issues: see (Xilinx Answer 44541).
A placer error can result when using the pblock constraints in the provided ".xdc" file. The errors are as follows:
ERROR: [Place 30-464] The packing of instances into a set of slices defined by a pblock constraint could not be obeyed. Please analyze your design to determine if the pblock can be resized or the number of LUTs, FFs, and/or control sets can be reduced.
ERROR: [Place 30-487] The packing of instances into a set of slices defined by a pblock constraint could not be obeyed. Please analyze your design to determine if the pblock can be resized or the number of LUTs, FFs, and/or control sets can be reduced.
ERROR: [Place 30-94] Place DRC : This design requires more Slice LUTs cells than what is available in PBlock 'SEM_CONTROLLER'. This design requires 1219 of such cell types but only 1200 compatible sites are available in PBlock 'SEM_CONTROLLER'. Please analyze your synthesis results and constraints
This issue can be resolved by increasing the size of the defined pblock in the constraints file. Refer to (Xilinx Answer 58045) for more details.
NOTE: "Version Found" refers to the version the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
