5.0.0.dev6 - PRE-RELEASE - 2025-05-11 (latest)

Download from PyPI | Commits since previous release

Bug Fixes

  • Updated Visualizer support to also work with Questa 2024.2. (#1096)

Features

  • Added support for running testbenches depending on a set of user-provided source files.

    The intended use case is to feed VUnit with files that have been changed since some point in time. The changes are typically provided by the version control system. (#1095)

  • Added support for repeating seeds from previous test run by setting the --seed option to repeat. (#1113)

  • Added support for test prioritization with two goals in mind:

    1. Prioritize likely failures - Tests more likely to fail are executed earlier to provide faster feedback.

    2. Load balancing - When tests are executed in parallel using the -p option, VUnit will try to keep the threads balanced to minimize total execution time.

    Added the --changed option that limits tests to those that depend on changes made after the last test run. (#1114)

Miscellaneous

  • Updated handling of disable_ieee_warnings for NVC 1.16 and later. (#1098)

5.0.0.dev5 - PRE-RELEASE - 2025-01-13

Download from PyPI | Commits since previous release

Bug Fixes

  • Added workarounds for Visualizer restart and stability issues. (#899)

  • Fixed array_axis_vcs example. (#1082)

Deprecations

  • Dropped support for Python 3.7 which reached end-of-life mid 2023. (#1091)

Features

  • Provided a unique base seed to every simulation. From that base seed any number of unique seed can derived to initialize the random number generators in the testbench. Unique seeds increase the test coverage for randomized tests over time as they are executed repeatedly by the user and the CI. The seed can be overrideen from the command line with the –seed option in order to reproduce failing tests. (#1089)

Miscellaneous

  • Added shebang to setup.py. (#1078)

  • Updated the setup GHDL action used in the GitHub CI. (#1092)

5.0.0.dev4 - PRE-RELEASE - 2024-12-11

Download from PyPI | Commits since previous release

Features

  • [Questa/Modelsim] Added support for 3-step flow and the Visualizer debugger.

    The 3-step flow is enabled by setting the simulation option modelsim.three_step_flow to True. Extra flags to the vopt step can be provided with the simulation flags modelsim.vopt_flags and modelsim.vopt_flags.gui in normal and GUI mode, respectively.

    The Visualizer debugger is enabled from the command line using the --debugger=visualizer option (in addition to the --gui option for GUI mode). The 3-step flow must be enabled for this feature while the default original debugger works with or without the 3-step flow.

    Note: There is a bug in Visualizer preventing the normal restart command from being used. Please use the vunit_restart command instead. (#899)

  • [GHDL/NVC] Arbitrary waveform viewers are now supported by passing the --viewer command line argument. As a consequence, ghdl.gtkwave_script.gui and nvc.gtkwave_script.gui are deprecated in favour of ghdl.viewer_script.gui and nvc.viewer_script.gui, respectively. The --gtkwave-args and --gtkwave-fmt command line arguments are deprecated in favour of --viewer-args and --viewer-fmt, respectively. ghdl.viewer.gui and nvc.viewer.gui can be used to set the preferred viewer from the run-file. If no viewer is explicitly requested, gtkwave or surfer is used, in that order. This also means that VUnit now uses surfer if gtkwave is not installed.

    [NVC] It is possible to get VCD waveform files by passing --viewer-fmt=vcd. (#1002)

  • Added timeout parameter to the wait_until_idle procedure in the synchronization verification component interface. A timeout will result in a failure. (#1054)

5.0.0.dev3 - PRE-RELEASE - 2024-08-15

Download from PyPI | Commits since previous release

Features

  • Added option to configure the logging simulation time format (unit and number of decimals). (#1044)

  • Added support for setting run_all_in_same_sim and fail_on_warning attributes from Python. (#1053)

5.0.0.dev2 - PRE-RELEASE - 2024-08-07

Download from PyPI | Commits since previous release

Breaking Changes

  • Changed default values for unconnected tkeep and tstrb inputs for AXI stream VCs to match the standard:

    • tkeep changed from all zeros to all ones

    • tstrb changed from all zeros to value of tkeep

    May affect existing code if these values are verified by the testbench despite being unconnected. (#1049)

Bug Fixes

  • Changed AXI stream slave to only verify tdata if both of tkeep and tstrb are set. Removed potential race condition an AXI stream master. (#1049)

5.0.0.dev1 - PRE-RELEASE - 2024-07-19

Download from PyPI | Commits since previous release

[Active-HDL] Defined the TCL variable vunit_tb_path during the evaluation of the activehdl.init_file.gui script. (#1033)

  • [NVC] VUnit now sets the NVC_CONCURRENT_JOBS environment variable to the value of the --num-threads argument which allows nvc to scale its worker thread count based on the number of concurrently running simulations. (#1036)

  • It is possible to use all logical CPUs by passing -p0 (--num-threads=0). See multiprocessing.cpu_count for how the number is determined. (#1039)

Public interface changes

Some run.py scripts can be broken by this. Both set_generic and add_config works differently internally.

set_generic and set_sim_option now only affects files added before the call so reordering within the run.py can be needed.

add_config on the test case level will no longer discard configurations added on the test bench level. This affects users mixing adding configurations on both test and test case level for the same test bench. Adding a configuration on the test bench level is now seen as a shorthand for adding the configuration to all test cases within the test bench. Configurations are only held at the test case level now. Before there could be configurations on multiple levels where the most specific level ignored all others. I now recommend writing a for loop over test_bench.get_tests() adding configurations to each test individually, see the updated generate_tests example.

We have also forbidden to have configurations without name (“”), this is since the default configuration of all test cases has no name. The post_check and pre_config can now be set using set_pre_config also without using add_config removing the need to add a single unnamed configuration and instead setting these in the default configuration.

This internal restructuring has been made to allow a sane data model of configurations where they are attached to test cases. This allows us to expose configurations objects on the public API in the future allowing users more control and visibility. The current behavior of configurations is also better documented than it ever was.

I suggest reading the section on configurations in the docs.
