QVLCOM may issue the following errors when compiling a VHDL file generated by NGD2VHDL or LogiBLOX:
-- Loading package standard -- Loading package std_logic_1164 ERROR: Could not open library simprim at simprim: No such file or directory ERROR: calc_tim.vhd(7): Library simprim not found. ERROR: calc_tim.vhd(8): Unknown identifier: simprim ERROR: calc_tim.vhd(9): Unknown identifier: simprim ERROR: calc_tim.vhd(10): VHDL Compiler exiting
解决方案
The problem comes about because the VHDL (VITAL) simprim and/or LogiBLOX libraries have not been compiled for use with VHDL.
For more information on compiling these libraries, see (Xilinx Solution 2478).
