Simulation and Verification

 Hi,

I have these lines in my code:

library UNISIM;
use UNISIM.Vcomponents.ALL

and when I tried to vcom the vhd file that has that code in modelsim, I got this error:

# ** Error: (vcom-11) Could not find unisim.vcomponents.
# ** Error: ./../rtl/rtl_reorg/psa_d/psa_core/clock_gen/dll_div_s3e.vhd(27): (vcom-1195) Cannot find expanded name: 'unisim.vcomponents'.
# ** Error: ./../rtl/rtl_reorg/psa_d/psa_core/clock_gen/dll_div_s3e.vhd(27): Unknown record element "vcomponents".
# ** Error: ./../rtl/rtl_reorg/psa_d/psa_core/clock_gen/dll_div_s3e.vhd(30): VHDL Compiler exiting

any idea how to resolve this??

many thanks

nevermind this...

I found it out... just had to copy all unisim vhd files to unisim directory of modelsim, and compile them separately...

hi

I have found the same problem as you discover. I read your solution but i dont' understand it. can you describe useing more detail exactly what files, from where and what is destination files to copy this things.

best regards

[rdelario]

you can find unisim files in your Xilinx installation directory, in my case:

C:\Xilinx\webpack10.1\ISE\vhdl\src\unisims

what I did was, I copied those necessary files to my simulation directory.  then, your modelsim .do file will have to compile them:

vcom -93 -explicit -reportprogress 300 -work unisim  {./XilinxCoreLib/unisim_vcomp.vhd}

  vcom -93 -explicit -reportprogress 300 -work unisim  {./XilinxCoreLib/unisim_VPKG.vhd}
   vcom -93 -explicit -reportprogress 300 -work unisim  {./XilinxCoreLib/bufg.vhd}
   vcom -93 -explicit -reportprogress 300 -work unisim  {./XilinxCoreLib/ibufg.vhd}
   vcom -93 -explicit -reportprogress 300 -work unisim  {./XilinxCoreLib/dcm_sp.vhd}

give that a try...

cheers

Copying the simulation library files to your working directory isn't the best way.  Instead you should run the compxlib program to compile the libraries correctly for your simulator.  More information can be found here:
