VHDL plugin for RgGen

RgGen::VHDL

RgGen::VHDL is a RgGen plugin to generate RTL written in VHDL.

Installation

To install RgGen::VHDL, use the following command:

$ gem install rggen-vhdl

Usage

You need to tell RgGen to load RgGen::VHDL plugin. There are two ways.

Using --plugin runtime option

$ rggen --plugin rggen-vhdl your_register_map.yml

Using RGGEN_PLUGINS environment variable

$ export RGGEN_PLUGINS=${RGGEN_PLUGINS}:rggen-vhdl
$ rggen your_register_map.yml

Using Generated RTL

Generated RTL modules are constructed by using common VHDL modules. You need to get them from the GitHub repository and set an envirnment variable to show their location.

• GitHub repository
  • https://github.com/rggen/rggen-vhdl-rtl.git
• Environment variable
  • RGGEN_VHDL_RTL_ROOT

$ git clone https://github.com/rggen/rggen-vhdl-rtl.git
$ export RGGEN_VHDL_RTL_ROOT=`pwd`/rggen-vhdl-rtl

Then, you can use generated RTL modules with your design. This is an example command.

$ simulator \
    -f ${RGGEN_VHDL_RTL_ROOT}/compile.f
    your_csr_0.vhd your_csr_1.vhd your_design.vhd
