CMake, SystemVerilog and SystemC utilities for creating, building and testing RTL projects for FPGAs and ASICs.

Includes:

  • CMake utilities for rapid building and testing RTL projects
  • SystemVerilog modules for creating high quality RTL projects
  • Modern C++ framework for UVM with SystemC for creating high quality and performance efficient tests for RTL projects

Benefits

  • Quick setup
  • Cross platform, cross IDE
  • No need to create separate scripts for simulation and synthesis
  • No need to create separate scripts for different tools (Intel Quartus, Xilinx Vivado, Verilator, ModelSim, ...)
  • Supports incremental compilation, run slow vendor IP core regeneration and different simulation and synthesis tools only if input source file changes
  • Supports parallel compilation, run slow vendor IP core regeneration and different simulation and synthesis tools in parallel
  • Maintain the same file consistency between simulation and synthesis for different tools
  • Share the same HDL source code base and IP cores for various FPGA projects
  • Integration with Continuous Integration (CI) and Continuous Deployment (CD) like Jenkins, Hudson, GitLab, etc.
  • Run RTL unit tests under ctest: pass/fail, time execution, timeout, parallel execution, tests selection
  • Run the same unit tests with different parameters
  • Easy to integrate with other projects as git submodule
  • Custom UVM printers: JSON
  • Modern HDL testing library written in C++11 using UVM-SystemC
  • Support for Clang 3.5 and later
  • Support for GCC 4.9 and later

Documentation

Examples

FPGA projects that use Logic utilities for creating, building and testing:

  • Virtio - Virtio implementation

Requirements

These 3rd party tools and libraries are required. They must be installed to build logic library:

These 3rd party tools and libraries are optional. They must be installed to build and run tests:

  • Verilator - simulator, lint and coverage tool
  • GoogleTest - C++ unit test framework
  • SVUnit - SystemVerilog unit test framework

These 3rd party tools and libraries are optional:

Workspace

  • README.md - this read me file in MarkDown format
  • LICENSE - license file
  • CMakeLists.txt - CMake root script for building and testing project
  • doc - configuration files for code documentation generator
  • rtl - RTL source files
  • src - C++ source files
  • include - C++ include headers
  • tests - unit tests and verification tests in SystemC using Google Test or UVM and SystemVerilog using SVUnit
  • cmake - additional CMake scripts for building project
  • scripts - additional scripts in TCL or Python for building project

Build

Clone project repository:

git clone git@github.com:tymonx/logic.git

Change current location to project directory:

cd logic

Create build directory:

mkdir build

Change current location to build directory:

cd build

Create build scripts using CMake:

cmake ..

Build project using CMake (generic):

cmake --build . --target all

Or build project using make:

make -j`nproc`

It is much faster to recompile project using Ninja rather than Unix makefiles:

cmake -G Ninja ..
cmake --build . --target all

Documentation

To build documentation:

cmake --build . target doc

Built HTML documentation can be found in:

doc/html

To view HTML documentation, open it using web browser:

<WEB_BROWSER> doc/html/index.html

Tests

Run all unit tests:

ctest

Run only unit tests for AXI4-Stream:

ctest -R axi4_stream

Waveforms from unit tests run under ModelSim are stored in:

modelsim/unit_tests/<unit_test_name>

Waveforms from unit tests run under Verilator are stored in:

verilator/unit_tests/<unit_test_name>

All unit tests logs are stored in:

Testing/Temporary/LastTest.log

Verilator Coverage

Run Verilator coverage after running all tests:

cmake --build . --target verilator-coverage

Verilator analysis

Enable Verilator analysis:

add_hdl_source(<hdl-module-filename>
    ANALYSIS
        TRUE
)

Run Verilator analysis for <hdl-module-name>:

make verilator-analysis-<hdl-module-name>

Run Verilator analysis for all HDL modules:

make verilator-analysis-all

Creating Intel FPGA Quartus project

Use add_quartus_project() function to create Quartus project:

add_quartus_project(<top_level_entity>)

Quartus project will be created under:

quartus/<top_level_entity>

RTL analysis and elaboration in Intel FPGA Quartus for top level entity:

cmake --build . --target quartus-analysis-<top_level_entity>

RTL compilation in Intel FPGA Quartus for top level entity:

cmake --build . --target quartus-compile-<top_level_entity>

RTL analysis and elaboration in Intel FPGA Quartus for all top level entities:

cmake --build . --target quartus-analysis-all

RTL compilation in Intel FPGA Quartus for all top level entities:

cmake --build . --target quartus-compile-all

Creating Xilinx Vivado project

Use add_vivado_project() function to create Vivado project:

add_vivado_project(<top_level_entity>)

Vivado project will be created under:

vivado/<top_level_entity>

RTL analysis and elaboration in Xilinx Vivado for top level entity:

cmake --build . --target vivado-analysis-<top_level_entity>

Using with other CMake projects

Change current location to another RTL project root directory:

cd <rtl_project_root_directory>

Clone and add logic repository to RTL project as git submodule:

git submodule add git@github.com:tymonx/logic.git

Add these lines to CMakeLists.txt root file:

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH}
    ${CMAKE_CURRENT_LIST_DIR}/logic/cmake
)

include(AddLogic)

enable_testing()

add_subdirectory(logic)

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
