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.
