Supported Simulators

The current list of supported simulators are:

• GHDL
• ModelSim
• Vivado
• ActiveHDL
• NVC

Installing

VHDLTest is distributed as a dotnet tool through NuGet.org and can be installed globally:

dotnet tool install -g DEMAConsulting.VHDLTest

VHDLTest --help

Additionally it can be installed as a local tool in the working folder:

dotnet tool install DEMAConsulting.VHDLTest

dotnet VHDLTest --help

Configuration

VHDLTest needs a YAML configuration file specifying the VHDL files and test benches.

# List of VHDL source files
files:
 - full_adder.vhd
 - full_adder_pass_tb.vhd
 - full_adder_fail_tb.vhd
 - half_adder.vhd
 - half_adder_pass_tb.vhd
 - half_adder_fail_tb.vhd

# List of test benches to execute
tests:
 - full_adder_pass_tb
 - full_adder_fail_tb
 - half_adder_pass_tb
 - half_adder_fail_tb

Running Tests

Before running the tests, it may be necessary to configure where the simulators are installed. This can be done through environment variables:

• VHDLTEST_GHDL_PATH = path to GHDL folder
• VHDLTEST_MODELSIM_PATH = path to ModelSim folder
• VHDLTEST_VIVADO_PATH = path to Vivado folder
• VHDLTEST_ACTIVEHDL_PATH = path to ActiveHDL folder
• VHDLTEST_NVC_PATH = path to NVC folder

To run the tests, execute VHDLTest with the name of the configuration file.

dotnet VHDLTest --config test_suite.yaml

A test results file can be generated when working in CI environments.

dotnet VHDLTest --config test_suite.yaml --results test_results.trx
