Xilinx device specific primitives

I need a list of device-specific primitives of Xilinx devices. I know that ISE has a list of templates and there are also PDF user guides but I need them as list of files in a folder so that I can parse them and extract name and port-list of every module.

Any help will be appreciated.

I have almost found what I wanted. Language templates are stored in location:

[install dir][version]\ISE_DS\ISE\data\projnav\templates

Look for the file named unisim_VCOMP.vhd. It has all the component declarations of the Xilinx primitives.

For ISE, this is located at

[install dir]\[version]\ISE_DS\ISE\vhdl\src\unisims

For Vivado,

[install dir]\[version]\data\vhdl\src\unisims

Note, for Vivado, if you have VHDL that has primitives from older devices, then use unisim_retarget_VCOMP.vhd, which retargets old primitives to 7 Series and Ultrascale equivalents. However, there are some cases when retargeting certain primitives is not possible.

If your code is for 7 Series and Ultrascale families, I wouldn't worry about the "retarget" file.

If you are using Xilinx ISE take a look at the folder "C:\Xilinx\14.7\ISE_DS\ISE\vhdl\src\unisims\primitive" (default install location, version may vary).
In this folder you will find VHDL files for all Xilinx primitives, not sorted by device however.
