Compiling simprim library in xilinx I get:

--> Compiling verilog simprim library
> Simprim compiled to C:\Xilinx92i\verilog\mti_se\simprims_ver
> Log file C:\Xilinx92i\verilog\mti_se\simprims_ver\cxl_simprim.log generated
> Library mapping successful, setup file(s) modelsim.ini updated

compxlib[simprims_ver]: No error(s), no warning(s)
Output directory => 'C:\Xilinx92i\vhdl\mti_se'

--> Compiling vhdl simprim library
> Simprim compiled to C:\Xilinx92i\vhdl\mti_se\simprim
> Log file C:\Xilinx92i\vhdl\mti_se\simprim\cxl_simprim.log generated
> Library mapping successful, setup file(s) modelsim.ini updated

compxlib[simprim]: 8 error(s), 1047 warning(s)

Log file (compxlib.log) generated.


Process "Compile HDL Simulation Libraries" failed

Q. Anybody has any idea what is wrong with simprim for vhdl...

I ignore the errors and simulate on modelsim. It in turn gives me the warnings:

** Warning: (vsim-3473) Component instance "madd_s_expsum_addsub0000_xor_1_q : x_xor2" is not bound.
# Time: 0 ps Iteration: 0 Region: /addexpunsig File: netgen/translate/AddExpUnsig_translate.vhd
# ** Warning: (vsim-3473) Component instance "madd_s_expsum_addsub0000_xor_2_q : x_xor2" is not bound.
# Time: 0 ps Iteration: 0 Region: /addexpunsig File: netgen/translate/AddExpUnsig_translate.vhd
# ** Warning: (vsim-3473) Component instance "madd_s_expsum_addsub0000_xor_3_q : x_xor2" is not bound

Are these errors related?? How can I solve them??

Hi,

> Q. Anybody has any idea what is wrong with simprim for vhdl...

Not without the error messages. Maybe you can post the log file

> Are these errors related?? How can I solve them??

Probably, depending on the library and use statement above the architecture/entity. The x_xor component has been specified in one of the Xilinx libraries: simprim, unisim or XilinxCoreLib. When these libraries have not been compiled yet, the simulator can not simulate this component and gives the warning "is not bound".
