Precompile Vendor Primitives
############################

Vendors like Altera, Lattice and Xilinx have their own simulation libraries,
especially for FPGA primitives, soft and hard macros. These libraries cannot
be shipped with *GHDL*, but we offer prepared compile scripts to pre-compile
the vendor libraries, if the vendor tool is present on the computer. There are
also popular simulation and verification libraries like OSVVM [#f1]_ or
UVVM [#f3]_, which can be pre-compiled, too.

The compilation scripts are writen in the shell languages: *PowerShell* for
*Windows* |trade| and *Bash* for *GNU/Linux*. The compile scripts can colorize
the GHDL warning and error lines with the help of `grc/grcat` [#f4]_.

Script Configuration
====================

The vendor library compile scripts need to know where the used / latest vendor
tool chain is installed. Therefore, the scripts implement a default installation
directory search as well as environment variable checks. If a vendor tool cannot
be detected or the script chooses the wrong vendor library source directory,
then it's possible to provide the path via `--source` or `-Source`.

The generated output is stored relative to the current working directory. The
scripts create a sub-directory for each vendor. The default output directory can
be overwritten by the parameter `--output` or `-Output`.

To compile all source files with GHDL, the simulator executable is searched in
`PATH`. The found default GHDL executable can be overwritten by setting the
environment variable `GHDL` or by passing the parameter `--ghdl` or `-GHDL` to
the scripts.

If the vendor library compilation is used very often, we recommend configuring
these parameters in `config.sh` or `config.psm1`, so the command line can be
shortened to the essential parts.

---------------------------------------------------------------------

Compiling on Linux
==================

* **Step 0 - Configure the scripts (optional)**

    See the next section for how to configure `config.sh`.

* **Step 1 - Browse to your simulation working directory**

  .. code-block:: Bash

    $ cd <MySimulationFolder>
    ```

* **Step 2 - Start the compilation script(s)**

  .. code-block:: Bash

    $ /usr/local/lib/ghdl/vendors/compile-altera.sh --all
    $ /usr/local/lib/ghdl/vendors/compile-lattice.sh --all
    $ /usr/local/lib/ghdl/vendors/compile-xilinx-ise.sh --all
    $ /usr/local/lib/ghdl/vendors/compile-xilinx-vivado.sh --all
    $ /usr/local/lib/ghdl/vendors/compile-osvvm.sh --all
    $ /usr/local/lib/ghdl/vendors/compile-uvvm.sh --all
    ```

    In most cases GHDL is installed into `/usr/local/`. The scripts are
    installed into the `lib` directory.

* **Step 3 - Viewing the result**

    This creates vendor directories in your current working directory and
    compiles the vendor files into them.


  .. code-block:: Bash

    $ ls -ahl
    ...
    drwxr-xr-x  2 <user> <group>  56K Mar 09 17:41 altera
    drwxr-xr-x  2 <user> <group>  56K Mar 09 17:42 lattice
    drwxr-xr-x  2 <user> <group>  56K Mar 09 17:48 osvvm
    drwxr-xr-x  2 <user> <group>  56K Mar 09 17:58 uvvm
    drwxr-xr-x  2 <user> <group>  56K Mar 09 17:58 xilinx-ise
    drwxr-xr-x  2 <user> <group>  56K Mar 09 17:48 xilinx-vivado
    ```


---------------------------------------------------------------------

Compiling on Windows
====================

* **Step 0 - Configure the scripts (optional)**

    See the next section for how to configure `config.psm1`.

* **Step 1 - Browse to your simulation working directory**

  .. code-block:: PowerShell

     PS> cd <MySimulationFolder>

* **Step 2 - Start the compilation script(s)**

  .. code-block:: PowerShell

     PS> <GHDL>\libraries\vendors\compile-altera.ps1 -All
     PS> <GHDL>\libraries\vendors\compile-lattice.ps1 -All
     PS> <GHDL>\libraries\vendors\compile-xilinx-ise.ps1 -All
     PS> <GHDL>\libraries\vendors\compile-xilinx-vivado.ps1 -All
     PS> <GHDL>\libraries\vendors\compile-osvvm.ps1 -All
     PS> <GHDL>\libraries\vendors\compile-uvvm.ps1 -All

* **Step 3 - Viewing the result**

    This creates vendor directories in your current working directory and
    compiles the vendor files into them.

  .. code-block:: PowerShell

     PS> dir
         Directory: D:\temp\ghdl

     Mode           LastWriteTime       Length Name
     ----           -------------       ------ ----

     d----    09.03.2018    19:40        <DIR> xilinx-vivado


---------------------------------------------------------------------

Configuration Files
======================

For Linux: `config.sh`
----------------------

Please open the `config.sh` file and set the dictionary entries for the
installed vendor tools to your tool's installation
directories. Use an empty string `""` for not installed tools.

`config.sh`:

.. code-block:: Bash

   declare -A InstallationDirectory
   InstallationDirectory[AlteraQuartus]="/opt/Altera/17.1"
   InstallationDirectory[LatticeDiamond]="/opt/Diamond/3.9_x64"
   InstallationDirectory[OSVVM]="/home/<user>/git/GitHub/osvvm"
   InstallationDirectory[UVVM]="/home/<user>/git/GitHub/uvvm_all"
   InstallationDirectory[XilinxISE]="/opt/Xilinx/14.7"
   InstallationDirectory[XilinxVivado]="/opt/Xilinx/Vivado/2017.4"


For Windows: `config.psm1`
--------------------------

Please open the `config.psm1` file and set the dictionary entries for the
installed vendor tools to your tool's installation
folder. Use an empty string `""` for not installed tools.

`config.psm1`:

.. code-block:: PowerShell

   $InstallationDirectory = @{
     "AlteraQuartus" =   "C:\Altera\17.1";
     "LatticeDiamond" =  "C:\Lattice\Diamond\3.9_x64";
     "XilinxISE" =       "C:\Xilinx\14.7\ISE_DS";
     "XilinxVivado" =    "C:\Xilinx\Vivado\2017.4";
     "OSVVM" =           "D:\git\GitHub\osvvm";
