errors in post-place & route simulation

xilinx post place and route simulation

when i do the post-place & route simulation in xilinx ISE, the modelsim window opens but i get alot of errors.

the errors are like

#         Searched libraries:
# ERROR: Could not open library simprims_ver at simprims_ver: No such file or directory
#             work
# ERROR: Could not open library simprims_ver at simprims_ver: No such file or directory
# ERROR: uart_timesim.v(2899): Instantiation of 'X_LUT4' failed (design unit not found).
#       Region: /stimulus/my_uart

and in some lines it says that Instantiation of 'X_FF' failed or Instantiation of 'X_OR2' failed

can someone tell me what i should do?

Have you compiled the Xilinx libraries for ModelSim? See "Compiling Xilinx Simulation Libraries (COMPXLIB)" in your Synthesis and Verification Design Guide.
