## Compile Scripts for Vendor VHDL Libraries

Vendors like Altera, Lattice and Xilinx have their own simulation libraries,
especially for FPGA primitives, soft and hard macros. These libraries can not 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][osvvm]
and [VUnit][vunit], which can be pre-compile, too.

The compilation scripts are writen in the shell languages: PowerShell for Windows
and Bash for Linux. The compile scripts can colorize the GHDL warning and error
lines with the help of grc/grcat ([generic colourizer][grc]).

### Script Configuration

The vendor library compile scripts need to know where the used / latest vendor
tool chain is installed. Therefore, the script implement a default installation
directory search as well as environment variable checks. If a vendor tool could
not be detected or the script choses 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 to configure
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 next section for how to configure `config.sh`.

 - **Step 1 - Browse to your simulation working directory**
    ```Bash
    $ cd <MySimulationFolder>
    ```

 - **Step 2 - Start the compilation script(s)**
    ```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-vunit.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.

    ```Bash
    $ ls -ahl
    ...
    drwxr-xr-x  2 <user> <group>  56K Nov 30 17:41 altera
    drwxr-xr-x  2 <user> <group>  56K Nov 30 17:42 lattice
    drwxr-xr-x  2 <user> <group>  56K Nov 30 17:48 osvvm
    drwxr-xr-x  2 <user> <group>  56K Nov 30 17:58 vunit
    drwxr-xr-x  2 <user> <group>  56K Nov 30 17:58 xilinx-ise
    drwxr-xr-x  2 <user> <group>  56K Nov 30 17:48 xilinx-vivado
    ```


---------------------------------------------------------------------
### Compiling on Windows

 - **Step 0 - Configure the scripts (optional)**
    See next section for how to configure `config.psm1`.

 - **Step 1 - Browse to your simulation working directory**
    ```PowerShell
    PS> cd <MySimulationFolder>
    ```

 - **Step 2 - Start the compilation script(s)**
    ```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-vunit.ps1 -All
    ```

 - **Step 3 - Viewing the result**
    This creates vendor directories in your current working directory and
    compiles the vendor files into them.

    ```PowerShell
    PS> dir
        Directory: D:\temp\ghdl

    Mode           LastWriteTime       Length Name
    ----           -------------       ------ ----
    d----    20.11.2015    19:33        <DIR> altera
    d----    20.11.2015    19:38        <DIR> lattice
    d----    20.11.2015    19:38        <DIR> osvvm
    d----    20.11.2015    19:45        <DIR> vunit_lib
    d----    20.11.2015    19:06        <DIR> xilinx-ise
    d----    20.11.2015    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 the appropriate directory to your tool's installation
directories. Use an empty string `""` for not installed tools.

`config.sh`:
```Bash
declare -A InstallationDirectory
InstallationDirectory[AlteraQuartus]="/opt/Altera/16.0"
InstallationDirectory[LatticeDiamond]="/opt/Diamond/3.8_x64"
InstallationDirectory[OSVVM]="/home/<user>/git/GitHub/osvvm"
InstallationDirectory[VUnit]="/home/<user>/git/GitHub/vunit"
InstallationDirectory[XilinxISE]="/opt/Xilinx/14.7"
InstallationDirectory[XilinxVivado]="/opt/Xilinx/Vivado/2016.3"
```

#### For Windows: `config.psm1`

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

`config.psm1`:
```PowerShell
$InstallationDirectory = @{
  "AlteraQuartus" =   "C:\Altera\16.0";
  "LatticeDiamond" =  "C:\Lattice\Diamond\3.8_x64";
  "XilinxISE" =       "C:\Xilinx\14.7\ISE_DS";
  "XilinxVivado" =    "C:\Xilinx\Vivado\2016.3";
  "OSVVM" =           "D:\git\GitHub\osvvm";
  "VUnit" =           "D:\git\GitHub\vunit"
