hi,
UVM_ML, developed by Cadence, indeed contains UVM_SV. But it also contains Multi Language capabilities, enable connecting packages implemented in SV, e, and SC.
For example - in the UVM_ML, the configuration DB serves all languages. So one can call config-set() from one language, and config-get() from another, hence configuring components implemented in another language.
Another example - the objection to End of Test is synchronised over framework so that the test is stopped only after all objections from all languages are dropped.
