SimplHDL 0.0.4

A framework for simulating and implementing HDL designs

Introduction

SimplHDL is a plugin-based command-line application for simplifying FPGA and ASIC development regardless of EDA tools and flows.

The goal is to embrase structured and reusable designs by creating a generic project model that can be used in any hdl development flow regardless of project structure and EDA tool requirements.

The plugin based architecture allows for SimplHDL to be migrated into any existing project, replacing ad-hoc simulation and implmentation scripts while providing a intuitive command-line interface for HDL design and verification engineers.

I wide vararity of languges, standards and tools are supported.

HDL languages

• Verilog / System Verilog
• VHDL
• Chisel
• SystemRDL
• IPXact
• Vivado IP containters (.xci, .xcix)
• Quartus IP containers (.ip)

• UVM
• OSVMM
• UVVM
• Cocotb
• pyuvm

EDA Tools

• Vivado
• Quartus
• Modelsim
• Questasim
• Xsim
• Vcs
• Riviera Pro
• Xcelium (coming)
• Verilator (coming)
• Icarus (coming)
• GHDL (coming)

Getting Started

SimplHDL currently works on Linux and Windows WSL. It is written in Python and can be installed with pip. To run SimplHDL Python 3.8 or later is required. The tools for the flows you wish to run also need to be installed and set up correctly in the shell environment. SimplHDL can be installed on your system's Python installation, but it is highly recommended to install and run SimplHDL in a Python virtual environment or a Conda environment.

Example

To quickly try out SimplHDL follow these steps. In this example, we will use Vivado and QuestaSim. The prerequisites are that SimplHDL install installed and Vivado and QuestaSim are correctly set up in your shell environment.

1. Clone Git repository from GitHub

git clone https://github.com/SimplHDL/simplhdl.git

2. install SimplHDL from source

pip install ./simplhdl

3. Run simulation

cd simplhdl/examples/hdl/alu/sim
simpl questasim

4. Run simulation interactively in Gui.

cd simplhdl/examples/hdl/alu/sim
simpl questasim --gui

5. Run implementation

cd ../syn
simpl vivado

6. Run implementation interactively in Gui.

simpl vivado --gui

In this example, the project specification is written in Yaml. This format is only meant as a demonstration. To integrate SimplHDL into your project, you have to write a parser plugin for your specific project specification format. See the documentation and plugin examples for more information.
