13.2 - CompXlib: Error: (vcom-11) Could not find unisim.vcomponents


When targeting Virtex 5QV in ISE/PlanAhead with a SIRF overlayer, library compilation for ModelSim SE might fails with the message below:

Error: (vcom-11) Could not find unisim.vcomponents.
C:/Xilinx/13.2/ISE_DS/ISE/vhdl/src/unimacro/ADDMACC_MACRO.vhd(29): use UNISIM.vcomponents.all;
Error: C:/Xilinx/13.2/ISE_DS/ISE/vhdl/src/unimacro/ADDMACC_MACRO.vhd(29): (vcom-1195) Cannot find expanded name "unisim.vcomponents".
Error: C:/Xilinx/13.2/ISE_DS/ISE/vhdl/src/unimacro/ADDMACC_MACRO.vhd(29): Unknown expanded name.


There seems to be a problem with the UNISIM library and the overlayer software.

The problem can be worked around by compiling the libraries for the commercial device: V-5FX130T.

The overlayer must be disabled before compiling the libraries for the commercial device.
